Radiology ReviewBreastUltrasound-guided marker placement improves breast lesion identification(Radiology Review) For patients with mammographically occult breast lesions, an additional lesion marker placed at needle localization may enable immediate confirmation of lesion excision, according to radiologists at New York University School of Medicine in New York City.December 29, 2008Digital X-RayAdding CsI-based dual-energy imaging doesn't improve lung nodule detection(Radiology Review) New research suggests that cesium iodide (CsI) detector-based dual-exposure dual-energy imaging, when added to chest radiography, does not significantly improve the detection or classification of pulmonary nodules.December 25, 2008CTMDCT identifies, depicts right adrenal vein(Radiology Review) Multidetector-row CT enables the identification and assessment of the right adrenal vein in most patients, according to Dr. Tomonori Matsuura and colleagues at Tohoku University Graduate School of Medicine in Sendai, Japan.September 16, 2008CTLow-dose CT offers first-line exam for suspected urolithiasis(Radiology Review) Low-dose CT is a useful imaging tool for patients with suspected urolithiasis, according to Swiss radiologists who performed a meta-analysis to evaluate its diagnostic performance.September 14, 2008CTGlobal RV function on ECG-gated 64-slice MDCT compares well with MRI(Radiology Review) Cardiac MDCT angiography for assessing coronary artery disease and coronary bypass grafts has enabled right ventricular (RV) function assessment, according to a study in the May issue of the American Journal of Roentgenology.July 3, 2008CT64-slice MDCT valuable for assessing coronary artery disease(Radiology Review) A comparison of 64-slice MDCT with intravascular ultrasound for coronary atherosclerotic plaques determined that 64-slice MDCT successfully identified disease, in particular for segments containing calcified plaques.July 3, 2008CT3-mm CT slices best for endovascular repair of AAA(Radiology Review) Multidetector-row CT (MDCT) of abdominal aortic aneurysms (AAA) treated with endovascular repair is best performed using 3-mm-thick images, according to a report in the December issue of the American Journal of Roentgenology. Researchers from Italy compared the sensitivity, specificity, and positive predictive values of different slice thicknesses for detecting endoleaks with MDCT.January 13, 2008Digital X-RayDual-source CTA improves temporal resolution for cardiac imaging(Radiology Review) Dual-source CT angiography (CTA) enables noninvasive, functional cardiac analysis, including accurate assessment of left ventricular myocardial function and reliable evaluation of regional wall motion, according to a pilot study by German researchers.December 27, 2007CTContrast-enhanced CT outperforms DSA for diagnosing abdominal bleeding(Radiology Review) Contrast-enhanced multidetector-row CT (MDCT) is more sensitive than aortic branch-selective digital subtraction angiography (DSA) for detecting active abdominal bleeding, according to an in vitro study by U.K. researchers.December 10, 2007MRICombining T2-weighted MRI and DWI improves prostate cancer detection(Radiology Review) Combined T2-weighted MRI and diffusion-weighted imaging (DWI) is significantly better than T2-weighted imaging alone for detecting peripheral zone prostate cancer, according to a report in the August issue of American Journal of Roentgenology.September 20, 2007Page 1 of 6Next PageTop StoriesWomens ImagingLobular breast cancer incidence risingInvasive lobular breast cancer incidence has risen by between 2.5% and 4.4% among women of various ethnic and racial backgrounds.MRIUse of solar energy could cut MRI, CT carbon emissions by 70% and 40%Digital X-RayWhat’s the environmental impact of x-ray and fluoroscopy?UltrasoundLinens, disposable items make up most of ultrasound's carbon footprintSponsor ContentDigital Innovations Shaping the Future of Radiology
