MR spectroscopy can improve specificity in breast cancer detection without losing sensitivity. And the acquisition and postprocessing of spectroscopic data are sufficiently user-friendly to become routine in a clinical setting, according to research More »

One out of five patients with breast cancer in a Spanish study had her therapeutic approach changed after undergoing contrast-enhanced MR imaging. Meanwhile, Italian researchers found CE MR valuable in detecting bilateral breast cancer. Dr. Julia More »

The use of ultrasound-guided vacuum-assisted breast biopsy devices should help reduce the need for rebiopsies, researchers in a large multicenter trial reported Monday. The study covered five centers in Canada, the U.S., and Europe and included More »

MR scored significantly better than unenhanced biphasic CT scans to detect aneurysmal endoleaks and to rate their size, according to researchers from the University of Mainz, Germany. Because of these differences, even within the various CT protocols, More »

Digital subtraction angiography was unable to visualize nearly 10% of 1127 arterial segments analyzed by researchers in the U.K. Because four-slice CT angiography picked up all those missed stenoses, DSA should not be considered the gold standard in this More »

GE Medical Systems is using the European Congress of Radiology to introduce two new hardware options with potential benefit to cardiovascular radiology. The company is adding to its range of digital fluoroscopy offerings with an imaging system optimized More »

If patients are hemodynamically stable, ruptured abdominal aortic aneurysms can be treated with stent grafting rather than surgical repair, Italian and Swiss researchers reported Monday. With about 100 cases reported in two unrelated studies, the More »

Ongoing technological improvements and sustained growth in the number of scanners worldwide are helping to fuel the rapid growth in clinical PET/CT. About 200 combined systems have been installed worldwide since the first PET/CT scanner was introduced More »

Steady but significant changes are occurring in how coronary calcification is imaged. Consensus is growing among researchers that the results of multidetector CT compare well with those of the gold standard, electron-beam CT, although they emphasise that More »

Radiologists are interested in characterizing the nature and permeability of blood vessels in patients with cancer because this information has many uses: to differentiate benign lesions from malignant ones, relate prognosis and treatment strategies to More »
