Mayo Clinic researchers will share their time-saving approach in this scientific session.November 5, 2012CTPerfusion CT evaluates effectiveness of antiangiogenic drugs in NSCLCTuesday, November 27 | 11:25 a.m.-11:35 a.m. | VSCH31-14 | Room N230Perfusion CT is more effective than Response Evaluation Criteria in Solid Tumors (RECIST) for evaluating the effectiveness of short-term antiangiogenic chemotherapy for non-small cell lung cancer (NSCLC), according to a group from Calmette Hospital and the University of Lille in France.November 5, 2012CTIterative reconstruction won't change diffuse lung disease diagnosisTuesday, November 27 | 11:20 a.m.-11:30 a.m. | SSG05-06 | Room S405ABThe use of iterative reconstruction brings important benefits, but it may have little effect on quantifying regional disease patterns in diffuse lung disease -- meaning the techniques can be used interchangeably, according to a study from University of Ulsan College of Medicine in Seoul, South Korea.November 5, 2012CTSpectral CT can differentiate gastric carcinomaTuesday, November 27 | 10:50 a.m.-11:00 a.m. | SSG16-03 | Room S403BSpectral CT can be used to distinguish moderately differentiated adenocarcinoma from poorly differentiated adenocarcinoma and is helpful for evaluating the differentiation state of gastric cancers, say researchers from China.November 5, 2012CTContrast-induced nephropathy incidence is overestimatedTuesday, November 27 | 10:50 a.m.-11:00 a.m. | SSG08-03 | Room S102DCarefully performed studies suggest that the incidence and severity of contrast-induced nephropathy (CIN) after IV contrast injection for CT studies has been overestimated, according to researchers from the Mayo Clinic in Rochester, MN, who examined the incidence and severity of CIN in a meta-analysis.November 5, 2012Previous PagePage 77 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
