Eric Barnes[email protected]Nuclear MedicineAnalysis favors coronary CTA over stress MPS for chest painIn most chest pain patients, coronary CT angiography (CTA) surpasses its rival -- stress myocardial perfusion scintigraphy (MPS) -- for diagnosing coronary artery disease, according to the results of a new model analysis comparing the two techniques.January 14, 2010CTStudy reveals lesions most likely to be dismissed by VC CADWhy do radiologists dismiss true-positive computer-aided detection (CAD) marks at virtual colonoscopy? Are there particular exam or polyp characteristics that lead to incorrect dismissals of CAD marks by radiologists? Researchers from London were eager to find out.January 13, 2010Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderJanuary 10, 2010Image ProcessingCTA motion model aims to improve cardiac function analysisDutch researchers used an automated coronary artery motion model to analyze cardiac function from electrocardiogram-gated coronary CT angiography (CTA) data. The method promises to improve cardiac function analysis and reconstruction interval selection, and even provide new information on coronary artery motion at different heart rates.January 10, 2010CTDSCT edges out 64-slice CT in coronary artery imagingCoronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.January 7, 2010CTColonoscopy surveillance barely lowers CRC ratesDespite frequent colonoscopic surveillance, patients whose advanced adenomas had been removed had higher-than-expected rates of colorectal cancer (CRC) at follow-up, according to a new surveillance study that followed patients for more than four years after polypectomy.January 7, 2010CTDSCT technique distinguishes 'rainbow' of kidney stone typesA new dual-source CT (DSCT) technique is able to distinguish between five types of kidney stones, offering the possibility of unprecedented detail in the noninvasive assessment of stone disease. The research could lead to improved management of patients with kidney stones.January 3, 2010CTAuntMinnie.com CT InsiderDecember 28, 2009Image ProcessingAutomated QCT offers hope for passive osteoporosis screeningA new quantitative CT (QCT) technique offers hope that osteoporosis scans could someday be performed passively -- and automatically -- from abdominal CT scans acquired for other clinical purposes, according to researchers from the U.S. National Institutes of Health in Bethesda, MD.December 27, 2009CTVC CAD aids experts in detecting intermediate polypsComputer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month.December 27, 2009Previous PagePage 133 of 258Next PageTop StoriesUltrasoundCEUS outshines color Doppler imaging for indeterminate kidney lesionsCEUS outperformed color Doppler ultrasound in a study focusing on indeterminate kidney lesions.Womens ImagingWomen's Imaging MinnieCast, Episode 2: Risk-based vs. annual mammography screening, part 1Digital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsMRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?
