Eric Barnes[email protected]CTContrast delivery key in coronary CTAIodine concentration and flow rate have important effects on diagnosing CT angiography data, including better assessment of mixed plaques and stenoses, according to Dr. Christoph Becker and colleagues from the University of Munich. The group's experiments with different delivery parameters in 64-slice CTA have led to new protocols that deliver contrast media more reliably.September 6, 2005CTPolyp measurements more accurate in 3DThree-dimensional endoluminal views of colonic polyps can be measured more accurately than corresponding 2D multiplanar reconstructions (MPRs), according to a report in the September issue of Radiology.September 5, 2005AIDespite flaws, lung CAD earns second-reader roleIn a new study from Canada, a popular lung CAD application proved its value as a second reader of low-dose thoracic CT studies, detecting lung nodules that had been missed in a double reading by radiologists. Yet the application also produced large numbers of false positives, and some troubling false negatives.September 4, 2005CTCMS approves VC after failed colonoscopy in MidwestBeginning October 16, Medicare in four Midwestern states will pay for a virtual colonoscopy (CT colonography) exam after diagnostic colonoscopy fails for any reason. The local coverage decision also authorizes an initial VC examination for two indications without the need for initial failed colonoscopy.August 29, 2005CTVC path-planning technique maximizes observable mucosaThe complex shape of the human colon makes manual planning difficult and time-consuming, and traditional path-planning tools can produce significant blind spots. So researchers from South Korea developed a new way of reducing unexamined regions of the colon, based on automated path planning.August 29, 2005CTECG gating: Worth the dose for some lung indicationsDoes the diagnostic value of ECG-gated pulmonary images justify the higher radiation dose? The answer is that it does, sometimes, according to Dr. Joseph Schoepf, associate professor of radiology and director of CT research at the Medical University of South Carolina in Charleston.August 28, 2005CTVC acquisition: Simple steps optimize imaging resultsRecent virtual colonoscopy studies are stark proof of the power of acquisition protocols to affect sensitivity, according to a leading VC researcher. When the virtual exam is performed correctly, he said, its accuracy rivals that of conventional colonoscopy. When the protocol is wrong, the results are unacceptable.August 23, 2005CTManagement strategies evolve as CT finds more lung nodulesCT's rapidly advancing capabilities, aimed at catching more cancers while they're potentially curable, have been the driving force behind the growth of lung cancer screening trials over the past decade. But what to do with the proliferation of lung nodules? Two thoracic imaging experts discuss the impact of CT's growing screening database, and offer advice on which nodules to biopsy, follow, or even ignore.August 18, 2005CTSerious extracolonic findings prevalent in screening, symptomatic VC patientsAsymptomatic screening subjects were nearly as likely as symptomatic patients to have extracolonic findings at virtual colonoscopy, radiologists in Italy have reported. The study, in a very mixed population of symptomatic and screening patients, also found a similarly high prevalence of serious extracolonic pathologies between the two groups.August 16, 2005CTAuntMinnie.com CT Radiology InsiderAugust 14, 2005Previous PagePage 204 of 258Next PageTop StoriesMolecular ImagingPET predicts faster cognitive decline in women than menWomen initially outperformed men at low brain tau levels, but the advantage diminished as tau levels increased over time.MRIUnclear explanations of contrast MRI exams heighten patient anxietyWomens ImagingMammography screening improves survival for late-stage cancersUltrasoundUltrasound MinnieCast, Episode 2: Body imaging with RUS-PATSponsor ContentHow Agentic AI Is Transforming Radiology Ops
