Eric Barnes[email protected]Clinical NewsDual-energy VC aims for noninvasive polyp evaluationDual-energy CT may find itself forging a new path in virtual colonoscopy by not only finding colorectal lesions but characterizing them in ways other noninvasive techniques cannot, according to a presentation at the International Society for Computed Tomography conference.June 1, 2010Clinical NewsNonlaxative PET/CT colonography is both feasible and effectiveFor individuals who need a highly accurate colon screening exam but can't tolerate a full bowel prep, nonlaxative PET/CT colonography may be just what the doctor ordered, according to a new study from the U.K. published this month in the Journal of Nuclear Medicine.May 26, 2010Clinical NewsVC shows high diagnostic yield after failed colonoscopyVirtual colonoscopy finds significant pathology in patients referred after failed colonoscopy, according to a study presented at the Digestive Disease Week meeting in New Orleans. The results show the need for a complete colon exam and highlight VC's strengths in detecting extracolonic abnormalities.May 5, 2010Clinical NewsFlexible sigmoidoscopy of dubious value after VCThe yield of additional pathological findings was quite low in a group of symptomatic patients who underwent flexible sigmoidoscopy after virtual colonoscopy screening, according to a poster presentation at this week's Digestive Disease Week meeting in New Orleans.May 3, 2010Clinical NewsSmall colon polyps on VC suggest presence of larger lesionsIndividuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.April 15, 2010Clinical NewsAutomated exposure control delivers uneven CT dose reductionReducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.April 14, 2010Clinical NewsCT shows abdominal fat is unreliable Crohn's treatment targetA few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.April 13, 2010Clinical NewsLess DNA damage seen after high-pitch coronary CTAHigh-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.April 8, 2010Clinical NewsOpen-source software increases colon polyp conspicuityVisibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software.April 5, 2010Clinical NewsCardiac cath delivers high radiation doses to operatorsThe rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses.April 4, 2010Previous PagePage 46 of 59Next PageTop StoriesMRIChristiane Kuhl gives insights to Der SpiegelBreast imaging pioneer Prof. Dr. Christiane Kuhl has given a Q&A interview to the German news magazine, Der Spiegel.
