Eric Barnes[email protected]Clinical NewsVC is cost-effective for screening; tiny polyps can be ignoredVirtual colonoscopy is a cost-effective way to screen for colorectal cancer -- provided that individuals with tiny lesions aren't referred for polypectomy, according to the results of a new study from France.July 14, 2009Clinical NewsVirtual colonoscopy preferred for surveillance follow-upPatients referred for polyp surveillance after virtual colonoscopy are more likely to opt for another VC exam at follow-up, Italian researchers report. But patients want their follow-up scans sooner rather than later.July 9, 2009Clinical NewsHigh-pitch cardiothoracic CTA skips breath-holds and high dosesA new way to use CT angiography (CTA) to scan fast-moving targets -- such as fidgety children and grown-ups with rapid heartbeats -- is becoming routine at a hospital in France.July 6, 2009Clinical NewsCARS report: Liver segmentation tool allows manual fixesBERLIN - German researchers believe they have found a better way to preserve the best aspects of automated and manual segmentation in CT liver images, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.June 30, 2009Clinical NewsCARS report: New CAD tool follows lung nodules over timeBERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.June 29, 2009Clinical NewsCARS report: Novel conebeam CT cuts breast dose, improves accuracyBERLIN - Dual-resolution conebeam CT accentuates the positives of conebeam breast imaging and eliminates (some of) the negatives, said a team from Texas in a presentation at the Computer Assisted Radiology and Surgery meeting.June 28, 2009Clinical NewsCARS report: Personalized medicine will dominate future careBERLIN - Medicine is undergoing a historic transition, moving away from a cookie-cutter model of care and toward individualized treatment strategies based on patient-specific models of disease and treatment. Imaging, biology, and mathematics are at the center of this new paradigm, according to Dr. Michael Vannier, who spoke at the opening of the 2009 Computer Assisted Radiology and Surgery (CARS) meeting.June 25, 2009Clinical NewsReaders undaunted by VC CAD false positivesRadiologists examining data from virtual colonoscopy studies can easily dismiss increasing numbers of false-positive detections generated by computer-aided detection (CAD) systems, researchers from the U.K. report. But the presence of more false positives makes reading less efficient.June 11, 2009Clinical NewsMR stress alone sufficient for myocardial perfusionUse of an automated postprocessing tool eliminates the need for both a stress and rest exam in myocardial perfusion MRI, according to researchers from Germany. They found that quantitative assessment of stress MRI images alone delivers the same diagnostic performance as semiquantitative evaluation of both stress and rest perfusion exams.June 11, 2009Clinical NewsVirtual colonoscopy CAD improves flat-lesion detectionComputer-aided detection (CAD) software can improve the detection of flat lesions at virtual colonoscopy -- as long as the lesions are at least 1 mm high. In a new study from Italy, CAD detected 94% of all flat lesions; however, radiologists dismissed a few of them incorrectly as false positives.June 4, 2009Previous PagePage 51 of 59Next PageTop StoriesMRIGerman group shows how to optimize whole-body MRIResearchers from Heidelberg and Hannover have tried to establish the most effective protocol for whole-body MRI for cancer detection in patients with Li-Fraumeni syndrome.CTTeam Sicily shines light on imaging of gunshot woundsMRIMRI predicts diabetes in obese patientsDigital X-RayNew procedure treats chronic pain in toe jointsSponsor ContentJoin Us!
