Eric Barnes[email protected]Clinical NewsAccurate, fast soft-plaque measurement seen with coronary CTAAutomated measurement of soft plaque in the heart using coronary CT angiography (CTA) was accurate compared to the gold-standard modality, intravascular ultrasound, and was far faster than manual methods, concluded a new report published online this month in Radiology.September 20, 2010Clinical NewsBundling of CAD software boosts lung lesion detection at CTRunning CT lung images through multiple computer-aided detection (CAD) applications delivers better results than any single algorithm alone, researchers are finding. This phenomenon is unleashing a minitrend that may be discomforting to CAD developers concerned about the success of their systems.September 20, 2010Clinical NewsCAD algorithm spots acute intracranial hemorrhageIn stroke treatment, time is brain, as they say, but the timely detection of acute intracranial hemorrhage can be difficult when dealing with subcentimeter lesions or inexperienced readers. A new computer-aided detection (CAD) system designed to detect blood clots in the brain could be a welcome addition.September 19, 2010Clinical NewsAdvanced VC tool serves up polyp locations for colonoscopyLarge polyps found at virtual colonoscopy are referred to optical colonoscopy for removal, and that's generally the end of the story. But VC-detected polyps can't always be found quickly and easily at colonoscopy, so an automated method of finding them might be just what the gastroenterologist ordered.September 16, 2010Clinical NewsStudy finds VC cost-effective if tiny polyps are ignoredVirtual colonoscopy is cost-effective for colorectal cancer screening, assuming that only patients with polyps 6 mm or larger are referred for polypectomy, a new French study has concluded. Removing the smallest lesions is not only prohibitively expensive, the yield in terms of additional cancer is minimal.September 8, 2010Clinical NewsAdvanced CT may have role in noncalcified plaque assessmentAdvanced MDCT scanning may be ready to play an important role in assessing noncalcified coronary artery plaque, say German researchers, who used a 256-detector-row scanner and plaque-volume measurement software to compare interobserver variability in patients with different types of plaque.September 7, 2010Clinical NewsCAD labels abdominal vessels with improved accuracyA new computer-aided detection (CAD) algorithm automatically labels abdominal arteries extracted from CT images. The work-in-progress system is more accurate and less dependent on error-prone features than previous CAD schemes, say researchers from Nagoya, Japan.September 1, 2010Clinical NewsBreast CAD helps find lobular carcinoma in situ lesionsComputer-aided detection (CAD) is making an elusive breast abnormality, lobular carcinoma in situ, a little clearer by highlighting the calcifications that often surround it, according to a new study from Wende Breast Care in Rochester, NY.August 19, 2010Clinical NewsCombined PET/CT CAD improves lung nodule detectionResearchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.August 5, 2010Clinical NewsEnhanced reference standard boosts CTA accuracyBorrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.August 3, 2010Previous PagePage 44 of 59Next PageTop StoriesWomens ImagingHybrid AI reading shows success in breast cancer screeningA Dutch team found that a hybrid reading strategy for screening mammography reduced radiologist workload by 38% without changing recall or cancer detection rates.Medical, Legal, and PracticeCooking robot gets rave reviews in TübingenMRIUltrasound plus MRI helps diagnose pain from rotator cuff tendinopathyMedical, Legal, and PracticePressure grows for more rigorous financial disclosureMRIMRI, CT findings correlate for assessing epicardial fat volume
