A prototype system developed by the University of Maryland was able, for a time at least, to dramatically boost and document the communication of critical results findings, according to a presentation Tuesday. It’s since been sent back to the drawing board for more work, but points to a solution to a problem that vexes radiologists nationwide.
Adolescent gymnasts are developing a wider variety of arm, wrist, and hand injuries than previously described in gymnast-related medical literature, according to a retrospective review presented Monday at the RSNA meeting.
Researchers using a massive database of radiology reports to identify 10-year trends in scanning practices found mixed results. The good news: CT scans of children increased only slightly. In adults, however, they increased more than 50%, with abdominal and chest scans leading the way.
Radiologists should take much greater care over the patient information contained in their PowerPoint files, according to researchers from the University of Michigan.
Physicians who are experienced in performing multislice coronary CT angiography can diagnose better, but acquiring the expertise is a time-consuming effort.
Noncontrast MR angiography provides an alternative to the more common contrast-enhanced MRA administered with a gadubutrol-based agent, according to a report presented at the RSNA meeting Tuesday morning.
