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
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.
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
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,
U.K. researchers are using contrast-enhanced MR imaging to identify the stability of carotid plaques. The technique holds potential for determining risk in atheroma patients and tracking plaque progression in response to treatment.
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
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
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
Whole-body MR imaging is a powerful clinical tool with wide-ranging clinical applications, both oncologic and nononcologic. It has the potential to dramatically alter the practice of radiology, according to Dr. Stephen Eustace, a radiologist from the
Diffusion tensor imaging is a relative newcomer in MR imaging. The ability to measure the molecular movement of water within cellular structures was first described less than 20 years ago.
Despite problems in the selection of appropriate imaging
