The manifestation of vascular Ehlers-Danlos syndrome frequently involves multiple vascular segments, with aneurysms and dissections being the most common imaging findings. The traditional practice of avoiding surgery until complications develop is being modified in select cases.

Transhepatic drainage of intraabdominal abscesses under sonographic and fluoroscopic guidance is safe and effective. Abscess content and volume did not affect drainage time, but the presence of a fistula increased the duration of catheter use. The rate of catheter-related complication was highest in the group with 8-French catheters. The rates in the groups with 10- and 12-French catheters did not differ significantly. We suggest the use of 10-French catheters for transhepatic drainage.

Percutaneous RFA using internally cooled wet electrodes is safe and provides successful local tumor control in patients with HCC. The safety and effectiveness of RFA using internally cooled wet electrodes are comparable to those reported in the literature using conventional RFA electrodes and are similar for nonsubcapsular and subcapsular tumors.

Biopsy and fiducial seed placement in the abdomen and pelvis can be performed in the same session rather than separately, with a high rate of technical success and without an increased risk of complications when compared with either procedure alone.

Esophagorespiratory fistula is much more common than airway narrowing as an airway complication. The rate of complications increases significantly in association with radiation therapy among patients with malignant esophageal stricture. Clinicians need to be aware of earlier airway complications and poorer prognosis among patients who undergo radiation therapy before placement of an esophageal stent than in patients who undergo radiation after stent placement.

Dexmedetomidine offers an option for pediatric sedation for MRI at community hospital–based outpatient settings. It preserves respiration but elicits deviations in blood pressure and heart rate that have not required pharmacologic intervention. Dexmedetomidine offers a safe, effective, and efficient agent for sedation for children undergoing MRI in an outpatient setting.

Focal cortical gyration anomalies can be detected at the early sulcation process stage. The process leading to abnormal gyration may evolve faster than physiologic ones and seems to be related to alterations of parenchymal layering occurring before 24 weeks’ gestation. Most focal cortical gyration anomalies evolve toward what is currently considered polymicrogyria.

DCE-MRI is useful in differentiating between septic hip arthritis and transient synovitis. If static contrast-enhanced coronal MRI is used, the optimal time for the acquisition of contrast-enhanced coronal MRI is approximately 3.5 minutes.

With currently established imaging criteria, correlation between MR arthrographic and wrist arthroscopic findings in the assessment of tears of the radioscaphocapitate and long radiolunate ligaments is inconsistent. Because of the increasing clinical importance ascribed to the extrinsic carpal ligaments, further work aimed at refining both imaging techniques and diagnostic criteria in the MRI evaluation of these structures is warranted to improve correlation with results obtained at arthroscopy.

Increased T1 and T2 signal is commonly seen within the proximal hamstrings but is not associated with symptoms of hamstring tendinopathy. Increased tendon size, peritendinous T2 signal with a distal feathery appearance, and ischial tuberosity edema are significantly associated with symptomatic hamstring tendinopathy but can be seen in asymptomatic individuals.

CTDIvol should not be interpreted as patient dose; this study has shown it to overestimate dose to the skin or eye lens. These results may be used to provide more accurate estimates of actual dose to ensure that protocols are operated safely below thresholds. Tilting the gantry or moving the scanning region further away from the eyes are effective for reducing lens dose in clinical practice. These actions should be considered when they are consistent with the clinical task and patient anatomy.

Eighty-kilovolt imaging with noise reduction can simultaneously increase lesion conspicuity and facilitate radiation dose reduction and image quality improvement at contrast-enhanced hepatic CT.

This article reviews key safety metrics that we think are relevant to radiology and discusses how to define the measures and how we are attempting to translate the metrics into a culture of safety.

Although our results were unable to show absolute noninferiority of iohexol compared with iopamidol because of a very small difference in increase in mean SCr from baseline (using a noninferiority margin of 0.04 mg/dL), this difference is likely of minimal or no clinical importance in outpatients undergoing CT with low risk for contrast-induced nephropathy.

Tumor perfusion quantified with gadobutrol-enhanced dynamic contrast-enhanced MRI can be used as a noninvasive surrogate parameter for monitoring the antiangiogenic, antiproliferative, and proapoptotic effects of sorafenib on prostate carcinoma allografts as validated with immunohistochemical analysis.

Hepatoportal sclerosis is characterized by caudate lobe hypertrophy and right hepatic lobe atrophy, preserved liver volume, and lack of the liver nodularity associated with portal hypertension. In advanced cases, liver nodularity and atrophy produce an imaging appearance indistinguishable from that of cirrhosis.

The purpose of this article is to address the implications of invasive diagnostic procedures recommended by a lung cancer screening protocol. In particular, we assess how many invasive procedures were recommended for benign nodules. MATERIALS AND METhODS. Between 2003 and 2009, 4782 high-risk current and former smokers were enrolled in a lung cancer screening study. A helical low-dose CT of the chest was performed. Morphologic features targeted were parenchymal nodules. The indication for biopsy was made according to the diagnostic algorithm provided by the International Early Lung Cancer Action Program. We recorded the time points of biopsy recommendation; shape, size, and growth of nodules; types of diagnostic procedures; complication rates; and final pathologic diagnosis. RES...

Relative to standard through-plane imaging, MaxVelocity more closely approximates echocardiography for noninvasive assessment of peak antegrade velocity. Improved accuracy is critical for surgical decision making in patients with aortic valvular disease. Therefore, MaxVelocity provides an easy approach to quantify peak velocity as part of a routine clinical MRI protocol.

Imaging the treated breast presents challenges because of its limited compressibility and overlapping features of benign posttreatment alterations and tumor recurrence. After lumpectomy and radiation therapy, mammographic findings such as breast edema, skin thickening, fluid collections, architectural distortion, and calcifications have characteristic sequences of evolution toward stability. Changes in the imaging appearance after stability has been achieved—including increasing asymmetry, an enlarging mass, increasing edema or skin thickening, and the development of pleomorphic calcifications within or near the operative bed—should alert the radiologist to possible tumor recurrence. When mammography or sonography is indeterminate, MRI may be useful in excluding rec...

Imaging the treated breast presents challenges because of its limited compressibility and the overlapping features of benign posttreatment alterations and tumor recurrence. After lumpectomy and radiation therapy, mammographic findings such as breast edema, skin thickening, fluid collections, architectural distortion, and calcifications have characteristic sequences of evolution toward stability. Awareness of these normal chronologic imaging findings for the conservatively treated breast minimizes unnecessary recall from screening and permits early detection of recurrent breast carcinoma.

As abnormal placentation becomes more prevalent, in large part due to the markedly rising rates of cesarean delivery, there is a need for accurate antenatal diagnosis of this condition to prevent maternal morbidity and mortality. Maternal and fetal outcomes can be optimized through multidisciplinary planning to achieve accurate diagnosis and anticipation of the extent of abnormal placentation in the antenatal period. Imaging findings of abnormal placentation have been described for both ultrasound and MRI, although limitations exist for each technique. Although ultrasound remains the primary screening modality for the detection of abnormal placentation, MRI is a complementary technique that should be considered when ultrasound is inconclusive or incomplete. Familiarity with MRI...

Whereas uterine and vaginal septa, vaginal agenesis, and unicornuate uterus can be managed surgically, other uterine anomalies tend to be managed clinically. Hence, appropriate management depends on a reliable assessment of pelvic anatomy. MRI can accurately display female pelvic anatomy and is, therefore, useful in guiding therapy.

Patients with ipsilateral cancer who have additional suspicious lesions identified on MRI require careful evaluation and biopsy to exclude additional sites of cancer that may impact surgical management.

No statistically significant difference was found between mammographic presentation and postsurgical outcome of LCIS versus ALH lesions. Surgical excision of these lesions is recommended as long as no evident criteria are provided to differentiate those that might be associated with an underlying malignancy.

The diagnosis of LCIS at needle core biopsy, in this small study, revealed that 84% of lesions either were malignant or were atypical or high risk at surgery, of which 33% were found to be carcinoma. Our findings suggest that LCIS should be excised when noted at core biopsy.

Patients with high-risk lesions associated with the lowest likelihood of malignancy (papilloma and radial scar) and without suspicious MRI findings can safely undergo follow-up instead of surgery. Because of the low negative predictive value, however, MRI is not helpful in cases of lobular neoplasia and atypical ductal hyperplasia, and all these lesions should be excised.

There is a wide spectrum of appearances of papillary lesions of the breast on MRI, ultrasound, and mammography. This variable appearance of papillary lesions makes differentiation of benign from malignant pathologies difficult on imaging, and tissue sampling is usually warranted.

To our knowledge, no studies to date show definitive and specific characteristics for high-risk lesions. Underestimation of malignancy on MRI-guided biopsy currently warrants surgical management for all high-risk lesions. There is a need for prospective larger power studies.

Nonthrombotic pulmonary embolism is an infrequent condition with various causes that can be life-threatening pathologic conditions. The entity presents a diagnostic challenge because of the low specificity of clinical symptoms and imaging signs. Awareness of the imaging features of nonthrombotic pulmonary embolism facilitates correct diagnosis and leads to appropriate patient care.

Integrating salient imaging findings with clinical history is crucial when approaching the diagnosis of subcutaneous soft-tissue masses. The diagnosis of endometriosis should be entertained when soft-tissue masses are seen in the distribution of a cesarean section scar in a woman of reproductive age. Pain, particularly with a cyclic pattern, is highly suggestive of endometriosis. If endometriosis is suspected on CT or ultrasound, MRI can be performed for further evaluation. Definitive diagnosis is made with biopsy. Because subcutaneous nodules are so amenable percutaneous biopsy, imaging features, although of interest, are somewhat ancillary to the diagnostic workup.

Contralateral cancer was found in 15 of 367 women (4.1%), with MRI showing 14 (93%). Eleven contralateral cancers (73%) were visible on PEM, but only three (20%) were recognized prospectively as suspicious. Lesions that are visible on PEM should be viewed as suspicious unless known to be benign by prior breast imaging or biopsy.

Proton MR spectroscopy can be used to identify key tissue metabolites and may serve as a useful adjunct to radiographic evaluation of musculoskeletal lesions. A pooled analysis of 122 musculoskeletal tumors revealed that a discrete choline peak has a sensitivity of 88% and specificity of 68% in the detection of malignancy. Modest improvements in diagnostic accuracy in 22 of 122 cases when absolute choline quantification was used encourage the pursuit of development of choline quantification methods.

Gadoxetate disodium–enhanced MRI had high accuracy in diagnosis of FNH and hepatocellular adenoma, and the hepatocyte phase improved their distinction. FNH enhances significantly more than hepatocellular adenoma. An enhancement ratio, particularly in the hepatocyte phase, can be potentially used as an additional distinguishing feature.

The pathophysiology of stroke has several complex mechanisms. Understanding these mechanisms is essential to derive neuroprotective agents that limit neuronal damage after ischemia. Imaging and clinical strategies aimed at extending the therapeutic window for reperfusion treatment with mechanical and pharmacologic thrombolysis will add value to existing treatment strategies. Acute ischemic stroke is defined as abrupt neurologic dysfunction due to focal brain ischemia resulting in persistent neurologic deficit accompanied by characteristic abnormalities on brain imaging. Knowledge of the pathophysiologic mechanisms of neuronal injury in stroke is essential to target treatment. Neuroprotective and thrombolytic agents have been shown to improve clinical outcome.

Percutaneous vertebroplasty improves restrictive ventilatory impairment, but this improvement requires approximately 1 month to occur. Greater improvement in restrictive ventilatory dysfunction was observed in patients who underwent multiple vertebroplasty procedures than those who underwent a single procedure and in patients who underwent treatment of thoracic vertebrae than those who underwent treatment of other vertebrae.

Extraskeletal osteosarcoma is a rare mesenchymal malignancy of soft tissue, histologically indistinguishable from primary osteosarcoma of bone. However, there are distinct differences in demographics, imaging features, prognosis, and management compared with osteogenic osteosarcoma. Imaging characteristics reflect tumor morphology, with only 50% of primary tumors showing mineralization. Metastases may or may not show mineralization, even if present in the primary tumor. The overall prognosis is poor.

Multilocular cystic RCC is a rare cystic lesion of the kidney that is low risk to the patient and benign in behavior. It has a variable imaging pattern, the Bosniak category ranging from IIF to IV. As multilocular cystic RCC lesions increase in complexity on images (higher Bosniak category), there is a corresponding increase in the volume of malignant cells lining the tumor and an increase in the presence of vascularized fibrous tissue. Regardless of the imaging appearance, the behavior of these tumors was benign in this study. Clinicians and radiologists should be aware that when this carcinoma is reported to occur, the patient has an excellent prognosis.

Posttreatment imaging assessment of high-grade gliomas remains challenging. Familiarity with the expected MR imaging appearances of treatment-related change and tumor recurrence will help distinguish these entities allowing appropriate management.

The use of kinetic curve type assessment or pharmacokinetic modeling in conjunction with high-resolution 3D breast MRI appears to offer similar improvement in diagnostic performance. Although morphologic analysis alone provides good characterization of breast lesions on MRI as benign or malignant, analysis of the lesion perfusion on DCE-MRI using either kinetic curve shape assessment or a pharmacokinetic modeling approach improves diagnostic accuracy.

The incidence of esophageal rupture after fluoroscopically guided esophageal balloon dilation was 14.7%. Almost all ruptures were type 1 or 2 and were successfully managed conservatively. Only 1.4% of the ruptures were type 3 and required active management. There was no procedure-related mortality in any patient. Therefore, in spite of the high incidence of ruptures, fluoroscopically guided balloon dilation is a safe procedure, particularly if a rupture is identified early and managed appropriately.

The development of portal or hepatic venous thromboses after RFA in patients with HCC is rare and usually is associated with favorable prognoses. Further investigation is warranted to elucidate whether venous thrombosis after RFA is related to local tumor progression around ablation zones.

Use of MPR MDCT images for pulmonary CTA in the diagnosis of PE in children significantly increases confidence, interobserver agreement, and interpretation time among faculty pediatric radiologists and radiology residents. Because use of MPR MDCT images results in significantly greater improvements in reading parameters for residents than for faculty members, the routine use of this technique by trainees should be encouraged.

Neuroimaging of abnormal pediatric thalami uses conventional MRI sequences and advanced techniques to characterize lesions. Although there is considerable imaging overlap, a tailored approach can facilitate diagnosis and management.

The sensitivity of on-call resident interpretation of CTA for aneurysms in SAH is lower than expected, with a potential for delay in diagnosis and management in a small number of patients. Focused training to carefully review apparent blind spots and the frequency of multiple aneurysms may reduce inaccuracies.

Lymphoceles are rare unilocular cystic neck masses that may mimic other congenital, infectious, and malignant neck cysts. When enhanced CT or MRI shows a unilocular, nonseptated, fluid density or intensity, and nonenhancing supraclavicular cyst in the posterior cervical space, lymphocele is an important part of the differential diagnosis. Atypical features warrant fine-needle aspiration or follow-up for confirmation.

Bone lesions that initially yield indeterminate results at percutaneous CT-guided bone biopsy often are subsequently shown to be malignant; vigorous pursuit of a diagnosis is recommended if initial results are indeterminate. Lesions showing fat or more sclerosis are more likely to be indeterminate; lesions with less sclerosis or smaller sclerotic rim are more likely to yield malignant results.

There is a moderate correlation between ADC values and Gleason score and between kep and microvessel density of prostate cancer. Although the strength of the correlations is insufficient for immediate diagnostic utility, these results warrant further investigation on the potential of multiparametric MRI to facilitate noninvasive assessment of prostate cancer aggressiveness and angiogenesis.

Fast kilovoltage-switching dual-energy CT is highly specific in excluding enhancement and moderately to highly sensitive in detecting enhancement of renal lesions. Of the available dual-energy CT techniques, iodine density measurement using a threshold of 2 mg/cm3 is most accurate in distinguishing enhancing from nonenhancing renal lesions.

Almost 4% of patients with prostate cancer, particularly those with intermediate- and high-risk disease, have gross locally advanced disease at endorectal MRI and have a significantly worse prognosis than matched controls. These patients may be candidates for more aggressive treatment.

Measurements of extramural tumor spread are more reproducible among different observers than are 5-mm distance measurements to the anticipated circumferential resection margin. This factor should be taken into account in the preparation and implementation of guidelines for neoadjuvant therapy for rectal cancer.

A subepithelial lesion with a lesion-to-aorta ratio less than 0.86 in the portal venous phase or not in the gastric antrum or duodenum is never a glomus tumor. On the contrary, a subepithelial lesion with hemangioma-like enhancement during dynamic CT is essentially a glomus tumor. On the basis of these CT findings, glomus tumor can be differentiated from other subepithelial lesions with high diagnostic accuracy.

Coronary artery dissection with aortic extension can be a fatal although infrequent complication. The coronary artery entry point is usually stented in the catheterization laboratory. Thereafter, CT is the imaging modality of choice for immediate confirmation of the presence of residual iatrogenic aortic dissection and evaluation of its extent and later noninvasive follow-up.

Chest wall composition has a significant correlation with image noise for cardiac CT. Therefore, strategies that target radiation dose reduction should incorporate adaptation to chest wall composition. These determinations become more significant given the current obesity epidemic.

Although COP is considered the most frequent cause of the reversed halo sign, the presence of nodular walls or nodules inside the reversed halo strongly favors a diagnosis of active pulmonary tuberculosis rather than COP.

Bone marrow is an organ that is evaluated routinely during MRI of the spine, particularly lumbar spine evaluation. Thus, it is one of the most commonly performed MRI examinations. T1-weighted MRI is a fundamental sequence in evaluating spinal marrow, and an understanding of T1-weighted MR signal abnormalities is important for the practicing radiologist.

Routine MRI of the spine provides useful evaluation of the spinal bone marrow, but nonroutine MRI pulse sequences are increasingly being used to evaluate bone marrow pathology. An understanding of MRI pulse sequences and the normal and age-related appearances of bone marrow is important for the practicing radiologist.
