Digital infrared thermal imaging (DITI) represents a readily available and biologically harmless method with increasing scientific and clinical interest for its use in diagnosing various inflammatory and malignant conditions, using standardized protocols and techniques. After careful reading of the mentioned article, we found the conclusions inconsistent and drawn after applying non-standardized protocols for use of DITI in such clinical setting (three thermographic imaging positions instead of five imaging positions). Furthermore, the authors of the article used a non-standardized protocol for evaluation of the obtained thermograph...

We are wrongly accused of drawing inconsistent conclusions from our data which indicate clearly the lack of usefulness of digital infrared thermal imaging (DITI) under the conditions of the test. Furthermore, it is stated that we did not use a standardized method. In fact we followed the manufacturer’s protocol and after imaging 50% of the patients, feedback on the quality of imaging was requested and obtained by the manufacturers. The protocol determined, amid various parameters, the number of images per patient, the position of the patient, the angle from which oblique images were taken and the room temperature. There was no need for close-up imaging due to the high resolution of the camera and digital image processing. The b...

The signal-to-noise and image homogeneity were evaluated. Fourteen (n=14) volunteers were examined at 3T using 3D isotropic T2-weighted sagittal and conventional 2D T2-weighted sagittal, axial, and oblique sagittal MRI. Multiplanar reformation (MPR) of the 3D T2-weighted sagittal dataset was performed simultaneously with image evaluation.

The renegotiated publishing contract with Elsevier begins with this issue and a number of other changes have been implemented to coincide. Immediately striking of course is the new cover and like it or loathe it, it is the face of Clinical Radiology for the immediate future. Inside these pages you will see an advertisement by our publisher informing you that their new website for College members is now available and I think that this is a truly valuable tool whether you use it for research purposes, CPD activity or simply trying to trace a topic of clinical interest relevant to your practice.

It focuses on the important issue of screening mammography and the impact on performance of volume of cases read. The authors argue that their data do not provide any evidence to suggest a relationship between years of film reading and film-reading performance, but one must be careful that this is not interpreted as evidence for the absence of a relationship. Their result could be as a result of insufficient statistical power due to low reader numbers, a limitation acknowledged by the author.

They present an evaluation of the published evidence and compare the accuracy, sensitivity, and specificity of the MRI information with the reference standard postoperative pathological assessment. Although MRI (particularly contrast-enhanced MRI) performs well in assessing the depth and extent of myometrial invasion, it appears to be less sensitive in identifying cervical involvement and the presence of metastatic lymph nodes. Although several groups who have assessed the use of MRI in endometrial cancer have proposed various potential benefits for its use in routine preoperative practice, as yet there is no evidence that it has improved treatment outcome in t...

This review discusses the value of magnetic resonance imaging (MRI) and novel MRI techniques (diffusion, perfusion, spectroscopy, blood oxygen level-dependent (BOLD)-MRI, and MRI with new contrast agents) in endometrial carcinomas. Contrast-enhanced MRI is the imaging technique of choice, and diffusion-weighted MRI may help to identify malignant lesions and assess myometrial invasion. Novel MRI techniques may potentially increase diagnostic accuracy, enabling a refined, tailored surgical procedure and better prediction of treatment outcomes.

Radiological features of pulmonary sarcoidosis are well known but extra-pulmonary manifestations can produce a plethora of non-specific imaging findings that can affect subcutaneous tissue, and the neurological, cardiac, gastrointestinal, urological, liver, spleen, and skeletal systems. In the literature, there are various case reports and specific system reviews but there are few reviews that encompass all the extra-pulmonary manifestations. In this paper, we comprehensively review the imaging features of extra-pulmonary sarcoidosis with characteristic features as well as atypical presentations.

IVC development is a complex process involving formation of anastomoses between three pairs of embryonic veins in the 4th to 8th week of gestation. Various permutations occur in the basic venous plan of the abdomen and pelvis resulting in variants such as isolated left IVC, double IVC, and retroaortic left renal vein. The majority of these anomalies are asymptomatic but occasionally present clinically with thromboembolic complications. However, awareness of their existence is important to avoid important diagnostic pitfalls and in preoperative surgical and interventional radiological planning. (Source: Clinical R...

The incidence of brown tumour is higher in primary, compared to secondary, hyperparathyroidism, and has been reported to be around 3%. In hyperparathyroidism, increased osteoclastic activity results in osteopenia and subperiosteal bone resorption. Reactive osteoblastic activity results in the ingrowth of fibrovascular tissue in the marrow spaces. These processes, in turn, cause microfractures and haemorrhage that provoke an influx of multinucleated macrophages. Repeated haemorrhage results in haemosiderin deposition within the osteolytic cysts and gives rise to the characteristic brown colour of the lesion.

However, they are not without their problems. Following the proliferation of magnetic resonance neuroimaging in recent years it has become clear that the spectrum of toxicity that these therapies produce ranges from subclinical white matter changes to overt brain necrosis. The effects are both direct and indirect and via different pathological mechanisms. Chronic and progressive changes can be detected many years after the initial intervention. In addition to leucoencephalopathic changes, grey matter changes are now well described. Changes may be difficult to distinguish from tumour recurrence, though may be...

It is proving invaluable in providing information that allows successful single-stage surgery. An inevitable consequence of the high sensitivity of MRI is that it will identify additional lesions that may or may not represent significant extra disease. This may complicate and delay the preoperative process.

There is good evidence for a mortality reduction from mammographic screening in women aged 40 to 49 years but a 1-year interval is required. The lack of specificity of screening in young women does remain a problem. There is no evidence to suggest that a single screen between the ages of 47 and 50 years within a programme screening at 3-year intervals will reduce mortality; the trials showing a mortality benefit in women in their 40s included multiple screening episodes and shorter screening intervals. There is no randomized, controlled trial evidence to support screening in women aged above 70 years and screening this age group will cause greater harm than in younger women through higher rates of ...

Therefore, the results from our study, which solely addressed the role of CT in the detection of HCC, should be taken in context of the focused question that the study aimed to address. Regarding the specific questions that Dr Low raised about the CT protocol: (1) the arterial phase that was performed in all examinations in our study used an automated aortic triggered arterial phase to ensure consistency.

Over the last decade computed tomography (CT) has been shown to be a valuable adjunct in post-mortem practices. Coronary artery imaging using post-mortem CT (PMCT) remains the last hurdle in universal adaptation of so-called “near virtual” or “minimally invasive” autopsy. Saunders et al. proposed targeted cardiac post-mortem angiography as a way forward to overcome this problem. The current work demonstrates that it is possible to diagnose coronary artery disease using PMCT coronary angiography. We agree with the authors that the method described is more cost-effective and is universally adoptable compared to the use of the adapted heart–lung...

It supplies a variable volume of the superior interventricular septum, and can contribute to collateralization of the other septal vessels. When part or all of the left coronary artery (LCA) arises anomalously from the right coronary sinus, its passage to the left may be in the same pathway as a cristal artery, bearing a tell-tale septal vessel arising from its proximal segment.

The authors described various pulmonary complications that may follow embolization of septic or other particulate injection material into the lungs. They did not mention that it is also possible for the injection needle itself to be the source of an embolus. Needle embolus is said to be a rare entity, but we have recently encountered it twice within our population of intravenous drug users and we believe it is worthy of attention.

We agree that everybody involved in spinal imaging understands what a prolapsed disc (bulged or protruded) refers to. However, the reliability of this terminology has proved to be, at best, only moderate, both when assessed among clinical radiologists in conditions close to routine practice or among the highly specialized experts in the spine field, participating in a clinical trial.

The hydatid cyst has a predilection to locate in the liver and lungs. Although many uncommon locations have been reported and the disease is rarely present in the mediastinum. The present report describes a case of hydatic cyst localized simultaneously in the anterior mediastinum and bilateral pulmonary arteries, which was thought to originate from innominate vein echinococcal invasion.

The complex anatomy and the communication between neck spaces means that infection can spread along fascial planes leading to life-threatening complications such as airway compromise, vascular erosion/thrombosis, neural dysfunction, and ultimately descending necrotizing mediastinitis. Imaging has an important role to play in identifying the extent of infection and the presence of complications.

In this review, the roles of each of these elements are described as well as common causes for their derangement. Haemostasis may be manipulated via pharmacological means and in recent years there has been a significant increase in the number of agents available for influencing haemostatic mechanisms. It is essential that radiologists are aware of these mechanisms and drugs if they are to perform image-guided procedures safely. In addition to describing the relevant pathways and drugs, practical tips are provided.

It has emerged as a first-line treatment for fibroids, given its safety and effectiveness. The goal of uterine artery embolization (UAE) is to induce haemorrhagic infarction of fibroids while maintaining endometrial and myometrial perfusion. The complication rate of UAE is less than hysterectomy and myomectomy. The largest series to date that has prospectively studied post-procedure complications in 400 consecutive patients and found an overall 8.5 % short-term complication rate and a 1.25 % serious complication rate.
