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,

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

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

A new miniPACS for the private-practice, nonhospital environment is under development by Agfa and could be introduced before the end of the year, a company representative said at the ECR on Sunday. The system is designed as a scalable, entry-level

MR angiography should be employed much earlier in the postoperative follow-up of severely ill patients with complex revascularization of cruropedal circulation, according to a German researcher during a Saturday scientific session at the European

One examination that frequently gives rise to internal discussions in our department is CT of the chest to detect pulmonary emboli. Apart from the fact that patients who needed a ventilation/perfusion scan had to be transported to another hospital site,

A cine phase-contrast MR sequence coupled with a spatial magnetization modulation sequence is proving to be a potent combination for evaluating aortic endoleaks, according to Stanford University researchers.Spatial magnetization modulation, or

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

MR spectroscopy can be used to assess the metabolic status of elite athletes' muscle fibers. This type of metabolic information might be useful for assessing training conditions or revealing individual predispositions to particular types of muscular

Interventional radiologists in the Netherlands are part of a comprehensive oncologic team that treats certain head and neck cancers with an intra-arterial chemotherapy protocol, according to a refresher course presentation on Saturday at the

Dose exposures during CT calcium scoring procedures can be reduced substantially without sacrificing scoring accuracy, according to studies presented Saturday by German and U.S. researchers. Using both phantom and human subjects and three separate

Healthcare managers have consistently underestimated the impact of a PACS on a hospital radiology department. These installations not only change the technology the medical staff uses but also have a fundamental effect on the working culture. They

Historically, BOLD MR imaging has been used for neurologic purposes. But Swiss researchers have found that oxygenation levels in calf muscle measured by functional MRI correspond to transcutaneous measurement of tissue oxygen tension.There have been a

Researchers gave MR and CT a split verdict in their relative abilities to image liver malignances during a scientific session Saturday. A team from Heidleberg University said MR arterioportography had a higher sensitivity and specificity than CT

Philips Speech Processing is continuing to broaden its portfolio of languages. The addition of Hungarian. marks the first step into Eastern Europe for native-language speech recognition.Radiologists have had a chance to test the Hungarian Radiology

Obtaining cleanly fused cerebral PET and CT images no longer requires a multimillion-dollar hybrid scanner. Austrian researchers have developed an external frame that can facilitate fusion of those modalities and also MR or SPECT. Researchers from the

Dynamic gadolinium-enhanced MR imaging can discriminate between patients with rheumatoid arthritis and psoriatic arthritis during the acute phase of the disease, according to research presented Friday at the ECR.Dr. Simone Banderali and colleagues from

Ultrasound operators who experience injuries caused by repetitive movements in the workplace may be the first in line to view Philips' new iU22 system, which is being launched globally at the ECR."We believe it's the most significant ultrasound

Digital mammography's replacement of screen-film has become inevitable now that head-to-head comparisons of the systems are showing little difference in performance. The sticking point now lies with the radiologists reading soft-copy mammograms, not with
