Eric Barnes[email protected]CTAdding CAD to virtual colonoscopy saves lives and moneyAdding computer-aided detection (CAD) increases the efficiency and cost-effectiveness of VC screening, according to a new model-based analysis. Most of the gains resulted from the use of CAD with inexperienced readers, but even with experienced readers VC cost-effectiveness improved substantially.February 23, 2009CTMRI, MDCT err in estimating cardiac functional parametersMRI and MDCT assessments of left ventricular functional parameters were inaccurate when evaluated on a moving heart phantom with known parameters, according to a study in European Radiology. CT, particularly dual-source CT, did outperform MRI, however.February 19, 2009CTACRIN study: Bigger images, slower pace improve VC sensitivityThe best virtual colonoscopy readers don't rush through their cases, and they don't try to squeeze more than one image on the monitor at a time. But sticking to their preferred reading method doesn't help them find more polyps, according to a new analysis of data from the National CT Colonography Trial (ACRIN 6664).February 15, 2009Digital X-Ray320-detector-row CT cuts dose in triple rule-out examsImage quality is high and radiation dose is low when the so-called triple rule-out protocol is used with 320-detector-row CT to scan patients with chest pain, according to researchers from Berlin.February 11, 2009CTAuntMinnie.com Virtual Colonoscopy InsiderFebruary 9, 2009CTCT screening catches small cell lung cancers earlierIn one of the largest studies yet to focus on a rare type of lung cancer, radiologists from Columbia University in New York City found that CT screening and treatment when indicated may spare the lives of patients with small cell lung cancer.February 9, 2009CTACRIN VC trial shows only small differences in bowel prepsThere was no runaway winner among the three bowel preps used in the recently published National CT Colonography Trial (ACRIN 6664), but there were certainly differences in how they performed, according to a research team from Arizona.February 8, 2009CTAuntMinnie.com CT InsiderFebruary 4, 2009CTVirtual colonoscopy beginners do better with 3D dataNovice virtual colonoscopy readers detect more polyps reading 3D endoluminal datasets of electronically cleansed data compared to 2D images. But experienced readers aren't daunted by either 2D datasets or fecal residues, turning in a similar performance regardless of the reading environment.February 4, 2009CTAt CT, not all PE are bad PEThanks to advanced CT scanners and the watchful eyes of emergency room physicians, the diagnosis of pulmonary embolism (PE) has risen significantly in recent years. Yet despite all the new PE cases doctors are finding, the mortality rate hasn't budged. Researchers in Rhode Island think they might know why.February 3, 2009Previous PagePage 150 of 258Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
