Eric Barnes[email protected]CTDiagnostic, screening VC comparable in extracolonic disease detectionCHICAGO - At the RSNA gastrointestinal sessions, Dr. Michael Zalis from Massachusetts General Hospital in Boston presented a study that compared the performance of low-dose screening VC with its diagnostic counterpart, including their relative accuracy for the detection of extracolonic pathology.December 5, 2004MRIMRI may determine which stroke-infarcted brain tissue is salvageableCHICAGO - In acute stroke patients, the decision to give thrombolytic therapy is a crudely calculated risk: Will tPA salvage infarcted but still-living tissue -- or merely heighten the patient's risk of bleeding? Researchers at Massachusetts General Hospital in Boston are hoping to demystify this leap of faith based on a technique that helps gauge the status of the individual infarct when therapy is being considered.December 2, 2004CTSmall size no predictor of benign renal massesCHICAGO - Renal masses are among the most common of incidental findings, and the increasing use of imaging in recent years has produced a fool's bounty of indeterminate lesions. Fortunately most are benign, and further evaluation is often reserved for masses 6 mm and larger.December 1, 2004CTAutomated CO2 insufflation improves VCCHICAGO - European researchers took a good long look at automated CO2 insufflation in virtual colonoscopy at the RSNA meeting on Tuesday -- and came away mostly upbeat.November 30, 2004CTAortic valve calcification equals aortic stenosisCHICAGO - Researchers in Germany have found that aortic valve calcification -- rarely measured on its own -- is closely correlated to the degree of aortic stenosis. As a result, the investigators are recommending the routine calculation of such annular calcifications in patients undergoing coronary CT calcium assessment.November 30, 2004CTVisualizing bile leaks, CT predicts need for trauma interventionCHICAGO - Bile leaks are a complication of blunt liver trauma, and determining which liver lacerations warrant surgery is critical work. But location may be more important than size when it comes to managing liver lacerations, according to a study presented Monday at the RSNA meeting.November 28, 2004CTHigher lung cancer risk seen in asbestos-exposed smokersCHICAGO - For smokers who were also exposed to asbestos, the risk of lung cancer is expected to be far higher than that of the general lung cancer screening population. Just how high a risk was the focus of a lung cancer screening study presented at the RSNA meeting on Sunday.November 27, 2004CTStudy finds high sensitivity in prepless VCAn important new study from Italy bodes well for virtual colonoscopy. In fact, it's good news for anyone who might be willing to undergo colorectal cancer screening if it weren't for the uncomfortable bowel prep.November 22, 2004CTMDCT advances oral and maxillofacial surgery practiceFrom assessing complex trauma injuries to planning difficult surgery, MDCT and reconstruction software have taken oral and maxillofacial imaging beyond the clay age, according to Dr. Jon Bradrick. Still, he says, the software isn't quite there yet.November 21, 2004CTVC billing: Still hazy after all these yearsToday's rules for virtual colonoscopy billing seem to defy the laws of logic, not to mention the art of medicine. But there is evidence that a sufficiently motivated practitioner can follow the rules and still manage to get paid once in a while.November 18, 2004Previous PagePage 214 of 258Next PageTop StoriesNuclear MedicineGenetic mutations linked to poor outcomes in Pluvicto patientsTP53, PTEN, and RB1 mutations may serve as prognostic biomarkers.Womens ImagingAI support leads to more cancers found on DBTCTPROMISE: Women face higher heart disease risk at lower plaque burdensMolecular ImagingPET predicts faster cognitive decline in women than menSponsor ContentHow Agentic AI Is Transforming Radiology Ops
