Eric Barnes[email protected]CTNIH urges new efforts to increase colorectal cancer screeningColorectal cancer screening rates in the U.S. are finally on the rise, reaching more than half of the eligible screening population. But real progress on expanding access will depend on "utilizing the full range of screening options and evidence-based interventions," according to a draft statement released today by the National Institutes of Health (NIH).February 3, 2010CTNew VC CAD algorithm reveals submucosal colon cancersA new computer-aided detection (CAD) algorithm goes beyond flat-polyp detection to find submucosally invading colorectal cancers with virtual colonoscopy. Researchers say the software offers an important alternative to traditional CAD feature classification that could improve the sensitivity of all VC studies.February 3, 2010Nuclear MedicineNIH tells scanner suppliers to include radiation monitoringThe U.S. National Institutes of Health (NIH) is requiring imaging vendors to include radiation dose-tracking technology in scanners they sell to the NIH as part of an effort to track radiation derived from imaging studies, according to the February edition of the Journal of the American College of Radiology.January 31, 2010CTPreoperative CT may reduce negative appendectomies in womenA 10-year review of more than 1,000 patients at a North Carolina hospital found that preoperative CT scans may reduce unnecessary surgeries in women of reproductive age with suspected acute appendicitis, according to an article published in the February issue of Radiology.January 27, 2010CTColon stenting no barrier to virtual colonoscopyFlexible metallic stenting of the colon is common in patients treated for occlusive colorectal cancers. But conventional colonoscopy isn't a good way to follow up on these patients postoperatively, say Korean researchers.January 26, 2010CTVC screening effective in Medicare-age screening cohortVirtual colonoscopy is effective in older screening subjects and does not result in a high rate of referral to invasive colonoscopy, according to a new study published in the February issue of Radiology. The researchers said their study indicates that VC screening could be valuable for the Medicare population.January 26, 2010CTPerfusion CT handily distinguishes malignant neck nodesIn a new study from Poland, perfusion CT showed impressive accuracy for distinguishing benign from malignant lymph nodes in a study of squamous cell cancer patients with suspected metastases.January 24, 2010Image ProcessingStroke assessment varies depending on CT perfusion softwareA new study from Japan has found significant differences in the ways that five different commercial software packages assess abnormal brain regions on CT perfusion scans. The variances could lead to errors in patient management, according to the researchers.January 21, 2010CTImaging shows that even mild COPD reduces cardiac efficiencyEven mild cases of chronic obstructive pulmonary disease (COPD) have serious effects on the heart and blood circulation, according to a study to be published Thursday in the New England Journal of Medicine. The analysis found that the same problems long associated with severe disease are also present in milder cases.January 19, 2010CTStanford MDCT meeting reboots as subspecialty societyCT is one of medical imaging's largest and most dynamic modalities, but it has never had a dedicated society to call its own. Until now. Organizers of the International Symposium on Multidetector-Row CT have moved to spin off their meeting from Stanford University into the International Society for Computed Tomography (ISCT), a new multinational medical society dedicated to CT.January 17, 2010Previous PagePage 132 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
