Large and medium-sized vessels are affected by many primary and secondary inflammatory disorders or mimicking conditions, often presenting similar imaging characteristics. Knowledge of distinctive imaging features such as location, length, and degree of vessel wall enhancement as well as the particular clinical settings will help the clinician in appropriately narrowing down the differential diagnosis.

Propensity score analysis showed that in the treatment of patients with unresectable hepatocellular carcinoma, TACE was associated with significantly better overall survival rates than was transarterial infusion therapy without embolization. TACE can be recommended as initial treatment of these patients.

In cases of persistent abscess despite adequate catheter placement, percutaneous catheter exchange over a wire is useful for salvage after the large majority of primary failures. In addition, performance of CT and fluoroscopic catheter injection before catheter exchange facilitates recognition of the predictors of a likely response to catheter exchange.

Pneumothorax frequently occurred and placement of a chest tube was occasionally required for pneumothorax after CT fluoroscopy–guided lung biopsy. To reduce the risk of pneumothorax necessitating chest tube placement, physicians should adopt the shortest needle path to the lesion.

Changes in BP and HR, especially bradycardia, are common during percutaneous RFA of hepatic lesions. Significant risk factors for severe cardiovascular inhibition include contact of the RFA zone with the branches of the central portal vein, old age, and female sex.

The overall incidence of major bleeding after imaging-guided percutaneous core needle biopsy is low. Recent aspirin therapy does not appear to significantly increase the risk of such bleeding complications.

Lung nodules in children with extrapulmonary malignancies showed a variety of patterns on CT. In the subgroup of lung nodules that underwent biopsy, none of the nodule features studied on CT reliably differentiated benignity from malignancy. (Source: American Journal of Roentgenology) American Journal of Roentgenology journals http://www.medworm.com/rss/comments.php?id=3289901 Fri, 19 Feb 2010 21:02:50 +0100 3289901 http://www.medworm.com/index.php?rid=3289900&cid=s_30478_37_f&fid=30478&url=http%3A%2F%2Fwww.ajronline.org%2Fcgi%2Fcontent%2Fabstract%2F194%2F3%2F766%3Frss%3D1 CONCLUSION. FDG PET/CT has higher sensitivity than MDCT in the identification of sites of recurrent and metastatic disease in patients with colorectal cancer and an elevated CEA level. The two techniques appear to have similar specificity.

Rhenium-188-DTPA-DG may be a potential agent for the diagnosis and radiotherapy of tumors. (Source: American Journal of Roentgenology) American Journal of Roentgenology journals http://www.medworm.com/rss/comments.php?id=3289899 Fri, 19 Feb 2010 21:02:50 +0100 3289899 http://www.medworm.com/index.php?rid=3289898&cid=s_30478_37_f&fid=30478&url=http%3A%2F%2Fwww.ajronline.org%2Fcgi%2Fcontent%2Fabstract%2F194%2F3%2F754%3Frss%3D1 CONCLUSION. Serial MRI showed transient abnormal signal intensity in the mesial temporal lobes in patients with HHV-6 encephalopathy but persistent abnormal signal intensity in both the mesial temporal lobes and the extratemporal regions in patients with HSE. CT in the early period showed no abnormality in patients with HHV-6 encephalopathy but definite abnormal findings in patients with HSE. These differences may be useful in the differential diagnosis of the two conditions.

Soft-tissue tumors of the pelvis, particularly malignant ones, extend into other compartments through specific pathways that are bordered by bones, ligaments, and fasciae. Such pathways include the greater sciatic foramen, the obturator foramen, the femoral canal, the muscular lacuna, the pelvic outlet, and the inguinal canal.

Fifteen minutes after contrast injection, a statistically significant difference between rheumatoid arthritis and psoriatic arthritis was found in synovial enhancement that might play an important role in differentiating the two diseases. (Source: American Journal of Roentgenology) American Journal of Roentgenology journals http://www.medworm.com/rss/comments.php?id=3289893 Fri, 19 Feb 2010 21:02:50 +0100 3289893 http://www.medworm.com/index.php?rid=3289892&cid=s_30478_37_f&fid=30478&url=http%3A%2F%2Fwww.ajronline.org%2Fcgi%2Fcontent%2Fabstract%2F194%2F3%2F709%3Frss%3D1 CONCLUSION. IV contrast-enhanced indirect MR arthrography appears to be an effective means of hip evaluation for labral tears. It does not appear to improve detection of cartilage abnormalities when compared with conventional MRI.

Program directors consider mentoring relationships to be an important resource for resident professional development and a potential resource to increase the proportion of residents pursuing academic careers and positions of leadership. Female residents may have specific mentoring needs that should be explored with further study.

The overall balance between the demand and the supply of radiologists shifted toward a surplus between 2003 and 2007. According to our measure, we judge there was a close balance in 2003, but a 3% surplus in 2007. The employment market seems generally, but not universally, to self-correct relative shortages and surpluses in individual geographic areas and subspecialties within a few years.

Multiple complications may occur after urinary diversion. Tumor recurrence is a major concern in patients with bladder cancer. CT has an important role in postoperative evaluation of patients with urinary diversion to identify correctable causes early to prevent deterioration in renal function and detect tumor recurrence in patients who had bladder cancer.

The perineural plexuses closely follow peripancreatic vessels, which are well depicted by contrast-enhanced 3D volume-rendered imaging, thus facilitating the diagnosis of extrapancreatic perineural invasion of pancreatic adenocarcinoma. (Source: American Journal of Roentgenology) American Journal of Roentgenology journals http://www.medworm.com/rss/comments.php?id=3289886 Fri, 19 Feb 2010 21:02:50 +0100 3289886 http://www.medworm.com/index.php?rid=3289885&cid=s_30478_37_f&fid=30478&url=http%3A%2F%2Fwww.ajronline.org%2Fcgi%2Fcontent%2Fabstract%2F194%2F3%2F660%3Frss%3D1 CONCLUSION. For each diagnostic error, we explore the reasons for the misdiagnosis and provide experience-based advice to avoid these mistakes. (Source: American Journal of Roentgenology) American Journal of Roentgenology journals http://www.medworm.com/rss/comments.php?id=3289885 Fri, 19 Feb 2010 21:02:50 +0100 3289885 http://www.medworm.com/index.php?rid=3289884&cid=s_30478_37_f&fid=30478&url=http%3A%2F%2Fwww.ajronline.org%2Fcgi%2Fcontent%2Fabstract%2F194%2F3%2F653%3Frss%3D1 CONCLUSION. Pseudoenhancement is frequently seen within ablation zones on contrast-enhanced ultrasound, particularly in deep echogenic lesions. However, pseudoenhancement follows enhancement of the parenchyma between the transducer and target. This observation is consistent with nonlinear propagation of the ultrasound beam, which increases with bubble concentration. Pseudoenhancement shows relatively late initiation, progression over time, and nonmarginal location; these findings are different from those seen in typical tumor recurrence, which shows early enhancement and washout at the margin of the ablation zone.

The extraperitoneal segment of the rectum and its surrounding adipose tissue are encased by a fascia, like a sleeve, that can be seen on CT and MRI in healthy populations. The fascia divides the rectal extraperitoneal space into the perirectal space and pararectal space, and it may prevent lesions of the rectum from spreading to other pelvic extraperitoneal spaces.

Assessment of liver attenuation by use of unenhanced CT represents an objective and noninvasive means for detection of asymptomatic hepatic steatosis, whereas clinical risk factor assessment is unreliable. Further longitudinal investigation is needed to determine the most appropriate attenuation threshold and the risk for disease progression to steatohepatitis and cirrhosis.

Sensitivity for prediction of resectability tends to be lower for patients with locally advanced pancreatic cancer that has been downstaged by neoadjuvant therapy, but this trend is not statistically significant. Interobserver variability for determination of resectability is statistically higher than for controls who did not receive preoperative therapy.

The proposed perfusion defect score had good correlation with RV/LV diameter ratio and CTA obstruction score. Therefore, acquisition of perfusion images at dual-energy CT may be helpful for assessing the severity of acute pulmonary embolism.

FDG PET/CT pattern analysis enables accurate assessment for staple line recurrence in patients with previous resection of colorectal cancer. The most reliable PET/CT pattern predicting staple line recurrence is an eccentric or perianastomotic mass on CT with corresponding eccentric or perianastomotic FDG uptake on PET. Background, diffuse (on one or both sides of the staple line), curvilinear, and focal patterns of FDG uptake do not correlate with recurrence in the absence of a mass on CT.

Radiologists interpreting bedside chest radiographs of ICU patients detect large pleural effusions 92% of the time and can exclude large effusions with high confidence. However, small and medium effusions often are misdiagnosed as parenchymal opacities (45%) or are not seen (55%). Pulmonary opacities often are missed (34%) but are rarely misdiagnosed as pleural effusions (7%).

Solitary dilated duct is a rare mammographic finding, this series being the largest reported to date. Although few cases are studied, solitary dilated duct appears to have a greater than 2% likelihood of malignancy, sufficiently high to suggest that a suspicious (BI-RADS 4a) assessment may be appropriate.

MR-directed ultrasound of MRI-detected lesions was useful for decision making as part of the diagnostic workup. Malignant lesions were likely to have an ultrasound correlate, especially when they presented as masses on MRI. However, the sonographic findings of these lesions were often subtle, and careful scanning technique was needed for successful MRI–ultrasound correlation.

Our results show that differences between screen-film mammography and FFDM in compression force and indicated compressed breast thickness were small. On average, FFDM had 22% lower mean glandular dose than screen-film mammography per acquired view, with sizeable variations in average FFDM doses by manufacturer.

Endometriotic cysts with enhanced mural nodules are not always complicated with malignancy. In elderly patients, the presence of large enhanced nodules on large endometriotic cysts is more likely to indicate malignancy.

As the search for a panel of biomarkers detecting cancer, let alone early-stage disease, progresses, diagnostic imaging will continue to play a critical role to confirm or refute these biomarker assays. Interestingly, recent studies using contrast-enhanced ultrasound have shown potential as an early-detection tool by detecting the aberrant vascularity required for tumor growth before the development of a mass. Thus, we propose that the use of proteomic-based biomarker discovery and contrast-enhanced ultrasound may serve as a promising combination to help accurately identify early-stage epithelial ovarian cancer to improve women's health care.

Ultrasound characteristics can be used to diagnose the classic-appearing nonneoplastic entities, benign neoplasms and malignancies. In cases in which the appearance of an ovarian mass is not classic, assignment of relative risk of malignancy using a multiparametric model is appropriate and beneficial for patient management.

The goal of imaging in ovarian cancer detection is to expeditiously distinguish benign adnexal lesions from those requiring further pathologic evaluation for malignancy. For lesions indeterminate on ultrasound, MRI increases the specificity of imaging evaluation, thus decreasing benign resections. CT is useful in diagnosis and treatment planning of advanced cancer. Although 18F-FDG-avid ovarian lesions in postmenopausal women are considered suspicious for malignancy, PET/CT is not recommended for primary cancer detection because of high false-positive rates.

To offer potentially life-saving interventions for at-risk family members, we propose that every woman newly diagnosed with ovarian cancer be offered genetic testing for BRCA1 and BRCA2 genes because mutations in these genes are the strongest known predictors of ovarian cancer risk.

With a matched radiation dose, the CBCT system for sinus study has comparable high-contrast resolution and inferior low-contrast resolution relative to the MDCT scanner. Because of the more severe image artifacts on the CBCT system due to the small field of view and the lack of accurate scatter and beam-hardening correction, the utility of the CBCT system for diagnostic tasks related to soft tissue should be carefully assessed.

CT is a valuable imaging technique in the diagnostic work-up of Behçet disease. CT effectively demonstrates vascular system involvement that is the main cause of mortality in these patients. CT is also effective in detecting mediastinal, pleural, and pulmonary parenchymal findings related to the disease.

EBV-related malignant lymphoproliferative diseases share common features with other aggressive lymphomas, including a high degree of extranodal involvement, tumor vascularization, and tumor necrosis. Cognizance of the particular underlying diseases and conditions associated with the development of EBV-related lymphoproliferative diseases and associated imaging results should provide more accurate diagnosis.

The rate of reproducibility of DCE-MRI parameters is in the range of 10%–20% and is influenced by lesion location, parameters being significantly more reproducible in the liver than in the lung. These findings provide the foundation for interpretation of results and design of clinical trials in which DCE-MRI studies are used to assess objective responses.

Ethylene vinyl alcohol copolymer embolization for hemoptysis of systemic arterial origin is feasible. The agent seems beneficial in the care of patients with recurrent hemoptysis after previous bronchial arterial embolization, patients who would be at high risk during embolization with microparticles, and patients who need embolization of large systemic arteries through small-caliber anastomoses.

Therapeutic strategies for the management of lymphoma are constantly being refined to improve long-term survival with the lowest risk of toxicity to the patient. PET/CT is accurate for baseline staging and yields important prognostic information for determining the most appropriate initial treatment. Used for evaluation of treatment response, PET/CT can depict residual viable malignant lesions with greater accuracy than can other imaging techniques. The findings thereby influence decisions about the need for additional or alternative treatment.

MRI-guided focused ultrasound therapy for leiomyoma can result in nonperfused volume ratio and shrinkage that exceed those in previous clinical trials because the treatment guidelines have been relaxed to allow a greater amount of tissue ablation. The results suggest that a larger nonperfused volume ratio can be achieved, resulting in greater shrinkage and improved relief of symptoms.

Neuroendocrine cell hyperplasia of infancy can have a characteristic appearance on high-resolution CT scans, the imaging findings being useful in differentiating neuroendocrine cell hyperplasia of infancy from other types of childhood interstitial lung disease. The appearance aids radiologists in suggesting a specific diagnosis but does not exclude this diagnosis; in 17–22% of cases, the readers in this study did not suggest the diagnosis of neuroendocrine cell hyperplasia of infancy when it was present.

Unilateral lumbar spondylolysis displayed radiologic differences in morphology of the isthmic defect itself and in ancillary findings of the adjacent structures based on the segment involved. Recognition of different ancillary features of unilateral spondylolysis with the use of a feasible diagnostic tool can be helpful for the diagnosis of cases in which a direct sign of isthmic defect is equivocal.

The ED from pediatric CBCT using the standard-dose mode was considerably higher than that of MDCT, whereas the ED for CBCT using the low-dose mode was comparable to that of abdominal MDCT. For abdominal CBCT in the pediatric phantom, the highest LARs were for colon and bladder cancers and the highest RRs were for stomach and liver cancers.

Since 1980, a disparity between population growth and radiology residency position growth has been sustained between the West and the rest of the country. This disparity is a consequence of California's policy of restricting medical school enrollment and radiology residency positions despite continual population growth.

Patients with highly vascularized metastatic RCC as shown by high baseline tumor blood flow appear to have a worse prognosis than those who do not. Tumor perfusion may be a useful biomarker of prognosis and additionally, in the future, may assist in treatment stratification. The potential utility of perfusion CT as an early response indicator was probably inadequately assessed in this study because of the limited antiangiogenic activity of interferon in metastatic RCC.

Objectively measuring changes in both tumor size and attenuation on the first CECT study after initiating targeted therapy for metastatic RCC markedly improves response assessment. Distinct patterns of disease recurrence are seen in patients with metastatic RCC on targeted therapy.

Split-bolus contrast injection and combined vascular–excretory phase scanning are adequate for studying potential renal donors and result in a marked decrease in multiphase scanning and, thus, in radiation dose.
