Eric Barnes[email protected]Image ProcessingMich. researchers hope to revamp lung CT image processingA new study at the University of Michigan aims to speed up image processing for low-dose CT lung cancer scans in the hopes of reducing reconstruction times to just a few minutes, which should result in lower radiation doses to patients.September 11, 2014CTCT contrast not tied to poor outcomes, even in at-risk patientsThe use of intravenous contrast before CT imaging is safe for most patients, according to a large study published online on Tuesday in Radiology. Researchers from the Mayo Clinic in Rochester, MN, found no difference in complication rates between patients who received contrast and those who did not.September 8, 2014CTNLST: CT lung screening more effective for older smokersA new analysis of data from the National Lung Screening Trial (NLST) has found that CT lung cancer screening is more effective for older smokers than younger ones. The study, published online Tuesday in the Annals of Internal Medicine, is sure to shape the roiling debate over whether Medicare should pay for CT lung screening.September 7, 2014CTStudy finds CT lung cancer screening highly cost-effectiveCT lung cancer screening is cost-effective in the Medicare-aged population, concludes a new study published in American Health and Drug Benefits that was tailored specifically to older individuals undergoing lung cancer screening with CT. Proponents of the exam hope it will add impetus to efforts to win Medicare reimbursement.September 1, 2014CTCAC best predicts heart disease in kidney patientsCoronary artery calcium (CAC) as calculated from CT scans was by far the best predictor of cardiovascular disease in individuals with chronic kidney disease, just as it is in the population at large, concludes a new study in the Journal of the American Society of Nephrology.September 1, 2014CTACR cries foul as DNA test beats CTC to Medicare approvalThe American College of Radiology (ACR) is crying foul after the U.S. Centers for Medicare and Medicaid Services recently approved a stool DNA test for colorectal cancer screening -- as reimbursement for CT colonography (CTC) continues to languish.August 27, 2014CTSegmentation technique supports coronary CADA new coronary artery segmentation and tracking method is showing promise for supporting computer-aided detection (CAD) schemes that can read coronary CT angiography scans to look for arteries blocked by both soft and calcified plaque, according to research published in Medical Physics.August 25, 2014Image-Guided SurgeryMRI-guided catheter could upgrade stroke treatmentA new steerable MRI-guided catheter can navigate through blood vessels from the groin to the brain in a search for clots to destroy, according to research from the University of California, San Francisco.August 21, 2014Advanced VisualizationAuntMinnie.com Advanced Visualization InsiderAugust 19, 2014CTDecade of lung CAD brings insight, but little daily useComputer-aided detection (CAD) is known to boost radiologist performance in the detection of lung nodules, and radiologists certainly need the help. But despite a decade of fine-tuning and some powerful new capabilities, CAD systems haven't found a place in daily practice at most imaging facilitiesAugust 18, 2014Previous PagePage 47 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
