Taiwanese researchers have found that contrasted-enhanced multidetector CT angiography is a perfect match for conventional angiography in differentiating between total and near-total occlusive disease and mapping the architectural landmarks of the
Diagnosing nasal lesions on the basis of CT and MR appearance alone can be difficult because many such lesions have nonspecific imaging characteristics. To resolve this problem, a group of radiologists led by Dr. Alla Godelman of Long Island College Hospital in Brooklyn, NY, have devised 10 principles of nasal imaging.
Computer-aided detection, initially restricted to mammography, is entering the functional imaging arena. CTI Molecular Imaging is showcasing CAD technology during the RSNA meeting on its Reveal PET/CT scanners, as well as the Reveal MVS PET/CT workstation. Under a recently inked exclusive agreement with R2 Technology, CTI has begun offering the first commercially available CAD system for multidetector CT examinations of the chest.
As Medicare passes through the congressional mill, the focus often turns to radiologists and the increasing cost of medical imaging. A recent report by Blue Cross/Blue Shield stated that radiologists are driving up healthcare costs. But Philadelphia researchers on Monday concluded that it is cardiologists -- not radiologists -- who are responsible for sharp hikes in dollars spent for medical imaging.
The first day of the RSNA meeting is always the best, perhaps because I have the most energy and enthusiasm. Ten years ago I didn't get tired until Thursday. Now I'm tired on Monday. I would like to blame it on changes in the meeting, but I have the same problem during a normal work week at home.
The Biliary Wallstent from Boston Scientific has been used for a decade for palliation of malignant obstructive jaundice. Although the newer Luminexx from German vendor Angiomed offers several theoretical advantages, researchers in the U.K. have found that those advantages do not hold up under close scrutiny.
Virtual colonoscopy is gaining in clinical stature as a viable screening tool for colon cancer, with high sensitivity and specificity in detecting colonic polyps. But proper technique and good patient preparation are key to success, according to research presented Monday.
A vendor-neutral method for integrating case input from any PACS workstation into a teaching file system was presented during a scientific session on Monday."This method requires no vendor cooperation, effort, or software modification," said Dr. David Avrin, of the department of radiology informatics at the University of Utah.
Radiologists who are most experienced at reading virtual colonoscopy studies may not deliver the most accurate results, according to a pilot study presented Monday.
Volumetric visualization with multidetector-row CT helps find and characterize gastric cancer. It should also be used for the preoperative staging of these malignancies, according to studies presented Monday morning.
