Effect of Surface Architecture on In Vivo Ultrasound Contrast Persistence of Targeted Size-Selected Microbubbles

Ultrasound in Medicine and Biology — Thu, 09 Feb 2012 08:13:48 +0100

Abstract: Ultrasound molecular imaging is a powerful diagnostic modality using microbubbles coated with targeting ligands specific for endothelial biomarkers. The circulation persistence of ligand-bearing contrast agents is a key determinant in their contrast enhancement and targeting capability. Prior studies have shown that targeted microbubbles with ligands attached to the shell using the conventional exposed-ligand architecture (ELA) could trigger undesired ligand-induced complement activation and decreased circulation time. Microbubbles with the buried-ligand architecture (BLA), however, were found to inhibit complement activation and prolong circulation time. In the present study, we extended the stealth BLA microbubble design to size-selected (4 to 5-μm diameter) microbubbles targe...

New Microembolus Size Estimator for Peripheral Blood Vessels

Ultrasound in Medicine and Biology — Thu, 09 Feb 2012 08:13:48 +0100

Abstract: Several factors affecting the power of Doppler scattered signal and, consequently, microembolus size estimation, may be eliminated when assessing the microembolus size via multiple measurements. A new microembolus size estimator is proposed based on the ratio of microembolus scattering cross-section in two directions and for two emission frequencies. Theoretical considerations indicate that the estimation of size of microembolic elements should be independent of the spatial distribution of the wave intensity, tissue attenuation and hardware factors. The simulation results indicate that this estimation only slightly depends on the material of the microembolus and acoustic properties of blood. The experimental results indicate that the accuracy of median size estimation increases w...

High-Frequency Ultrasound in the Evaluation of Cerebral Intraventricular Haemorrhage in Preterm Rabbit Pups

Ultrasound in Medicine and Biology — Thu, 09 Feb 2012 08:13:48 +0100

Abstract: Cerebral intraventricular haemorrhage (IVH) is the most common cause of severe neurologic impairment following preterm birth in human infants. Ideally, an animal model for cerebral IVH should allow for reliable noninvasive evaluation of haemorrhagic extension and of subsequent development of posthaemorrhagic ventricular dilatation (PHVD). The aim of this study was to evaluate the use of high-frequency ultrasound (HFU) in premature rabbit pups with cerebral IVH induced by IP glycerol injection. Serial examinations using HFU enabled an accurate description of haemorrhagic extension and measurement of progressive PHVD over 72 h. The coefficient of variation for inter- and intraobserver variability in two measurements of ventricular size was less than 8.8% and 9.3%, respectively. Rep...

Radical Radiotherapy for Localised Hormone Refractory Prostate Cancer

Clinical Oncology — Thu, 09 Feb 2012 08:13:42 +0100

Introduction: Since PR07 and the Scandinavian Prostate Cancer Group showed survival benefit from adding radical radiotherapy (RT) to androgen deprivation therapy, prostate RT is routinely offered to fit patients with locally advanced prostate cancer [1,2]. Previously these patients were treated with hormones alone and followed up. Adding prostate RT when they become hormone refractory (and still have radiologically localised cancer) is controversial, but there is some evidence that patients with locally advanced hormone refractory prostate cancer (HRPC) may benefit [3]. The natural history of non-metastatic HRPC is unknown and treatment options are limited. Metastatic HRPC is associated with poor prognosis; widely quoted survival being 12–18 months, which with PSA lead time may be an und...

Sunitinib Malate in the Treatment of Metastatic Renal Cell Carcinoma: the North of England Cancer Network (NECN) Experience

Clinical Oncology — Thu, 09 Feb 2012 08:13:42 +0100

Introduction: Metastatic renal cell carcinoma (mRCC) has a poor prognosis. Treatment aims to improve progression free survival (PFS) and overall survival (OS). Sunitinib gained NICE approval in March 2009 as first line treatment and experience with it is growing. The NECN was the first in the UK to approve the use of Sunitinib in July 2007. This retrospective re-audit compares the NECN patient outcomes with published literature, updating previous NECN work from 2008. (Source: Clinical Oncology)

Multi-institutional Outcome Following LDR Brachytherapy in Patients with Higher Risk Prostate Cancer

Clinical Oncology — Thu, 09 Feb 2012 08:13:42 +0100

We report the outcomes for a cohort of men with higher risk prostate adenocarcinoma treated with LDR brachytherapy in a multi-institutional UK practice. Materials and methods: 217 men treated between 2003 and 2007 with iodine-125 brachytherapy at Christie, Leeds and Mount Vernon were identified from a multi-institutional database. Higher risk was defined as patients with≥2 D'Amico intermediate risk factors (PSA 10–20, GS 7 or clinical T2c) or ≥1 high risk factor (PSA>20, GS≥8). Kaplan–Meier methods were used to estimate biochemical relapse free survival (BRFS) defined using both Phoenix and ASTRO definitions. A univariate analysis was performed to assess the significance of Gleason score, PSA, T-stage, pre- or post-implant dosimetry, and additional hormones on BRFS. (Source: Cli...

Student Concerns and Misconceptions about A Career in Radiology

Academic Radiology — Thu, 09 Feb 2012 07:45:53 +0100

Year after year, medical students pose questions that reflect the same concerns and misconceptions about a career in radiology. While radiology educators and practicing radiologists may perceive many of these reservations as ill-founded or misguided, they are nonetheless important to recognize and address. Student decisions about careers are determined not only by what students know, but also by what they think they know. If students opt for radiology or eschew it based on inaccurate information, this benefits neither the students nor the field of radiology. In what follows, we briefly identify and suggest strategies for educating students about a dozen concerns and misconceptions. (Source: Academic Radiology)

Simultaneous bilateral hip joint imaging at 7 Tesla using fast transmit B1 shimming methods and multichannel transmission – a feasibility study

NMR in Biomedicine — Tue, 07 Feb 2012 05:00:00 +0100

The objective of this study was to demonstrate the feasibility of simultaneous bilateral hip imaging at 7 Tesla. Hip joint MRI becomes clinically critical since recent advances have made hip arthroscopy an efficacious approach to treat a variety of early hip diseases. The success of these treatments requires a reliable and accurate diagnosis of intraarticular abnormalities at an early stage. Articular cartilage assessment is especially important to guide surgical decisions but is difficult to achieve with current MR methods. Because of gains in tissue contrast and spatial resolution reported at ultra high magnetic fields, there are strong expectations that imaging the hip joint at 7 Tesla will improve diagnostic accuracy. Furthermore, there is growing evidence that the majority of these hi...

Metabolism of hyperpolarized [1‐13C]pyruvate in the isolated perfused rat lung – an ischemia study

NMR in Biomedicine — Tue, 07 Feb 2012 05:00:00 +0100

We report studies of the effect of ischemia on the metabolic activity of the intact perfused lung and its restoration after a period of reperfusion. Two groups of rat lungs were studied using hyperpolarized 1‐13C pyruvate to compare the rate of lactate labeling differing only in the temporal ordering of ischemic and normoxic acquisitions. In both cases, a several‐fold increase in lactate labeling was observed immediately after a 25‐min ischemia event as was its reversal back to the baseline after 30–40 min of resumed perfusion (n = 5, p < 0.025 for both comparisons). These results were corroborated by 31P spectroscopy and correspond well to measured changes in lactate pool size determined by 1H spectroscopy of freeze‐clamped specimens.

Contrast‐enhanced MRI of murine myocardial infarction – Part I

NMR in Biomedicine — Mon, 06 Feb 2012 05:00:00 +0100

The use of contrast agents has added considerable value to the existing cardiac MRI toolbox that can be used to study murine myocardial infarction, as it enables detailed in vivo visualization of the molecular and cellular processes that occur in the infarcted and remote tissue. A variety of non‐targeted and targeted contrast agents to study myocardial infarction are available and under development. Manganese, which acts as a calcium analogue, can be used to assess cell viability. Traditionally, low‐molecular‐weight Gd‐containing contrast agents are employed to measure infarct size in a late gadolinium enhancement experiment. Gd‐based blood‐pool agents are used to study the vascular status of the myocardium. The use of targeted contrast agents facilitates more detailed imaging ...

Contrast‐enhanced MRI of murine myocardial infarction – Part II

NMR in Biomedicine — Mon, 06 Feb 2012 05:00:00 +0100

Mouse models are increasingly used to study the pathophysiology of myocardial infarction in vivo. In this area, MRI has become the gold standard imaging modality, because it combines high spatial and temporal resolution functional imaging with a large variety of methods to generate soft tissue contrast. In addition, (target‐specific) MRI contrast agents can be employed to visualize different processes in the cascade of events following myocardial infarction. Here, the MRI sequence has a decisive role in the detection sensitivity of a contrast agent. However, a straightforward translation of clinically available protocols for human cardiac imaging to mice is not feasible, because of the small size of the mouse heart and its extremely high heart rate. This has stimulated intense research i...

Manipulation of cortical gray matter oxygenation by hyperoxic respiratory challenge: field dependence of R2* and MR signal response

NMR in Biomedicine — Mon, 06 Feb 2012 05:00:00 +0100

In conclusion, the R2* response to hyperoxic respiratory challenge was stronger for carbogen than for oxygen, and increased quadratically with the static magnetic field strength for both challenges, which highlights the importance of high field strengths for future studies aimed at probing oxygen physiology in clinical settings. Copyright © 2012 John Wiley & Sons, Ltd.In this study, the R2* response of the cortical gray matter to respiratory challenges was quantified at 1.5, 3 and 7 T. Hyperoxic challenges resulted in a decrease in the relaxation rate at all field strengths. The response to hyperoxic hypercapnia was 1.3 times larger than to hyperoxia. Both challenges led to a quadratic increase in the R2* response with B0. High field strengths may allow the probing of oxygen physiol...

Tumors invading the cavernous sinus that cause internal carotid artery compression are rarely pituitary adenomas

Pituitary — Fri, 03 Feb 2012 17:52:53 +0100

Abstract There is a clinical impression that when tumors invade the cavernous sinus, compression of the internal carotid artery is rare with pituitary adenomas and more common with other types of lesions but there are no actual data to support this impression. To confirm the impression that the finding of internal carotid artery compression by tumors invading the cavernous sinus is inconsistent with a diagnosis of a pituitary adenoma, we performed a retrospective analysis of MRI scans performed between 2000 and July 2009. An initial search of the radiology database was performed using the terms “invasive mass cavernous MRI” and subsequent refinement narrowed the evaluation to 141 patients with cavernous sinus invasion by sellar/parasellar tumors for whom there were cli...

Are intravenous injections of contrast media really less nephrotoxic than intra-arterial injections?

European Radiology — Fri, 03 Feb 2012 17:11:57 +0100

Abstract We oppose the opinion that the intra-arterial administration of iodine-based contrast media (CM) appears to pose a greater risk of contrast medium-induced nephropathy (CIN) than intravenous administration since 1) in intra-arterial coronary procedures and most other intra-arterial angiographic examinations, CM injections are also intravenous relative to the kidneys, 2) there is a lack of comparative trials studying the risk of CIN between intra-arterial and intravenous procedures with matched risk factors and CM doses, 3) a bias selection of patients with fewer risk factors may explain the seemingly lower rate of CIN after CT in comparison with coronary interventions, 4) the rate of CIN following intra-arterial coronary procedures may also be exaggerated owing to ...

Metal artefact reduction in gemstone spectral imaging dual-energy CT with and without metal artefact reduction software

European Radiology — Fri, 03 Feb 2012 17:11:57 +0100

Conclusion Dual-energy CT with GSI-MARs can reduce metal-related artefacts and improve the delineation of the prosthesis and periprosthetic region. We should be cautious when using GSI-MARs because the image quality was affected by the prosthesis composition, energy (in keV) and DFOV. The metallic composition and size should be considered in metallic imaging with GSI-MARs reconstruction. Key Points • Metal-related artefacts can be troublesome on musculoskeletal computed tomography (CT). • Gemstone spectral imaging (GSI) with dual-energy CT (DECT) offers a novel solution • GSI and metallic artefact reduction software (GSI-MAR) can markedly reduce these artefacts. • However image quality is influenced by the prosthesis...

New device removes stroke-causing blood clots better than standard treatment

UCLA Newsroom: Health Sciences — Fri, 03 Feb 2012 14:00:00 +0100

An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association's 2012 international conference in New Orleans on Feb. 3. The SOLITAIRE Flow Restoration Device is among an entirely new generation of devices designed to remove blood clots from blocked brain arteries in patients experiencing stroke. It has a self-expanding, stent-like design and, once inserted into a clot using a thin catheter tube, it compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel. In the first U.S. clinical trial of SOLITAIRE, the device opened blocked ve...

The gold standard technique for measuring gastric emptying is scintigraphy using radiolabeled test meals. Recently, a standardized radiolabeled solid meal has been proposed and adopted by many centers. There is still a need for alternative meals, and several such meals with demonstrated radiolabel stability have been evaluated in small numbers of subjects. Updated radiation dosimetry associated with these meals has been calculated for adult males and adult females with normal gastrointestinal transit as well as transit abnormalities.

Methods for the Assessment of Small-Bowel and Colonic Transit

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

Transit assessment of the small intestine and colon is relevant in the study of physiology, pathophysiology, and pharmacodynamics, and there is increasing use of small-bowel and colonic transit measurements in clinical practice as well. The main methods that are applied in clinical practice are substrate-hydrogen breath tests for small-bowel transit and radiopaque markers for colonic transit. Over the past 2-3 decades, scintigraphy has become the preferred standard in research studies, particularly for studies of pathophysiology and pharmacodynamics. New approaches include experimental stable isotope measurement of orocecal transit and the recently approved method using a wireless motility capsule that is validated as an accurate measurement of small-bowel and colonic transit.

Advancing Gastric Emptying Studies: Standardization and New Parameters to Assess Gastric Motility and Function

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

For many years, gastric emptying (GE) studies were performed using various local protocols and different radiolabeled meals. This lack of standardization and normal values made the test results unreliable and difficult to compare from one site to another. A recent consensus has been published that now provides guidance and standardization on how to perform a radiolabeled solid-meal GE study. It is widely recognized, however, that simple measurement of total GE of a solid meal often does not provide an answer to the etiology of symptoms for a large number of patients who present with functional dyspepsia. Advances in our understanding of the different roles of the fundus and antrum and their complex interaction with the proximal small bowel and central nervous system have led to the develop...

Hepatobiliary Scintigraphy in Acute Cholecystitis

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

Hepatobiliary scintigraphy is a mature imaging technique for evaluation of patients with acute cholecystitis (AC). It is effective in calculous and acalculous forms of AC. The test is used in contemporary medical practice as the arbiter when the findings from screening abdominal ultrasound do not fit a clinical picture. It is also performed in severely ill patients who have AC suspected on other testing, but whose frail condition and high operative risk demand the highest level of certainty. This review, therefore, examines all technique variations of hepatobiliary scintigraphy, offering an approach that may best fit a variety of clinical situations and philosophies on AC.

Sincalide Cholescintigraphy—32 Years Later: Evidence-Based Data on Its Clinical Utility and Infusion Methodology

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

Sincalide cholescintigraphy was first reported to have clinical utility in 1980. Since then, many publications have found that a reduced gallbladder ejection fraction (GBEF) can confirm the clinical diagnosis of acalculous chronic gallbladder disease and predict symptomatic relief with cholecystectomy. However, some publications had not found the test clinically predictive. Many different sincalide infusion methods and normal values have been used. It had been suspected that the different infusion methods and normal values might account for the variability in reported utility. Furthermore, clinical review articles have raised questions about the evidence-based quality of the published data on the diagnostic utility of sincalide cholescintigraphy. A recently published multicenter trial has ...

Guest Editorial: Gastrointestinal Nuclear Medicine: Are We Making Progress?

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

In my last guest editorial on gastrointestinal (GI) nuclear medicine in the Seminars in Nuclear Medicine in October 1995, I pointed out that there are few, if any, other nuclear medicine studies, such as gastric emptying, that are considered a gold standard with which other methods need to be compared. I stressed, however, that there was the need for continued efforts within the nuclear medicine community to prevent tarnishing this gold standard. Since then, we have made significant progress especially in standardizing gastric emptying. Additional progress, however, still needs to be made to prevent new imaging and nonimaging technologies from replacing scintigraphy as the primary modality for assessing gastric emptying. In this edition of Seminars, I have brought together several leaders ...

Letter from the Editors: Functional Studies of the Gastrointestinal Tract

Seminars in Nuclear Medicine — Fri, 03 Feb 2012 08:29:31 +0100

As pointed out by Dr. Alan Maurer in his guest editorial, it has been more than 15 years since he guest edited another Seminars issue, a two-part review of gastrointestinal (GI) nuclear imaging. A significant portion of the progress that has been made relates to attempted standardization of several of these studies. In particular, cooperative efforts between GI, radiology, and nuclear medicine societies have resulted in standardized methodology for gastric emptying studies. Whereas, half-time of emptying (T1/2) was previously considered the accepted key value or “gold standard,” current thoughts center more on the retention values at specific time intervals; particularly four hours post-ingestion of a labeled solid egg meal. Additionally, several alternative test meals yielding similar...

Blood metabolite data in response to maximal exercise in healthy subjects

Clinical Physiology and Functional Imaging — Fri, 03 Feb 2012 08:02:39 +0100

SummaryMaximal exercise test with gas exchange measurement evaluates exercise capacities with maximal oxygen uptake (VO2max) measurement. Measurements of lactate (L), lactate/pyruvate ratio (L/P) and ammonium (A) during rest, exercise and recovery enhance interpretative power of maximal exercise by incorporating muscular metabolism exploration. Maximal exercise test with gas exchange measurement is standardized in cardiopulmonary evaluations but, no reference data of blood muscular metabolites are available to evaluate the muscular metabolism. We determined normal values of L, L/P and A during a standardized maximal exercise and recovery in 48 healthy sedentary volunteers and compared with results obtained in four patients with exercise intolerance and a mitochondrial disease. In healthy s...

Study Suggests Surgical Breast Biopsy Not Overused

Health News from Medical News Today — Fri, 03 Feb 2012 08:00:00 +0100

Contrary to earlier findings, surgical breast biopsies may not be as overused as previously thought, according to a study in the February issue of the Journal of the American College of Radiology. Surgical breast biopsies are more invasive than needle biopsies, requiring an incision and the use of general anesthesia. Results from a previous study in 2011 in a surgical journal suggested that surgery is used for 30 percent of breast biopsies, an excessive number... (Source: Health News from Medical News Today)

Computerized detection of lung nodules by CT for radiologic technologists in preliminary screening

Radiological Physics and Technology — Fri, 03 Feb 2012 07:19:35 +0100

Abstract In Japan, radiologists and radiologic technologists are endeavoring to improve the quality of lung CT screening. In particular, preliminary screening by radiologic technologists is expected to decrease radiologists’ burden and improve the accuracy of CT screening. We considered that an application of computer-aided detection (CAD) would also be as useful in preliminary screening as in the radiologist’s regular reading. Our purpose in this study was to investigate the potential of the application of CAD to preliminary screening. CAD software that we developed was applied to 17 lung CT scans that radiologic technologists had pre-interpreted. A radiologist recognized 29 lung nodules from the CT images, whereas radiologic technologists did not recognize 11 of the ...

Neurodevelopmental delay in small babies at term. A systematic review.

The Ultrasound Review of Obstetrics and Gynecology — Fri, 03 Feb 2012 05:00:00 +0100

Authors: Arcangeli T, Thilaganathan B, Hooper R, Khan KS, Bhide A Abstract Background: Being small for gestational age (SGA) or having fetal growth restriction (FGR) may be associated with poorer neurodevelopmental outcomes compared to being appropriate for gestational age (AGA). The aim of this paper was to evaluate the existence and magnitude of decrease in neurodevelopmental scores in SGA and FGR infants born at term from a systematic review of the existing literature. Methods: Studies of neurodevelopment in SGA/FGR babies were identified from a search of the internet scientific databases. Studies which included preterm births and those that did not define absolute indices of standardised cognitive outcome were excluded. SGA was defined as birthweight below the 10(th) centile fo...
