Eric Barnes[email protected]CTInnovation notwithstanding, CT has a long wish listSAN FRANCISCO - The speedy evolution of CT technology in recent years might lead one to believe that the modality has finally arrived. And it has, if one considers the vast improvement that today's multislice technology represents over the single-detector-row scanners of the early 1990s, a time when pathologies were spotted in the grainy 2D shadows that presaged today's exquisitely detailed images.June 15, 2005Practice ManagementNew efforts urged to 'save' pediatric radiologyAccording to a recent Society of Pediatric Radiology report, 100 pediatric radiology positions went unfilled in the U.S. in 2003, and by the end of 2004 the total had risen to 117. Is the subspecialty in crisis? The authors of a June Radiology editorial think so, and suggest a number of creative ideas for reinventing pediatric radiology.June 13, 2005CTPrepless VC yields high sensitivity in average-risk subjectsVirtual colonoscopy researchers in Italy have steered a tough combination of study constraints all the way to a successful outcome. Beginning with a prepless exam and ultralow-dose CT protocol, the group produced high sensitivity and a high negative predictive value for VC in an average-risk asymptomatic patient population.June 9, 2005CT3D topological thinning improves colon centerline tracking in VCIn a new study, researchers from Dublin City University in Ireland solved the problem of computational overload in a common task required of software for 3D endoluminal views of the colon. They found that automated colon centerlines can be calculated much faster with the use of a lookup table in the topological data thinning algorithm.June 7, 2005CTAuntMinnie.com Virtual Colonoscopy Radiology InsiderJune 5, 2005CTPerfusion CT, MRI agree on most stroke parametersImaging of acute stroke patients at admission accurately predicts follow-up infarct size with both perfusion CT and diffusion-weighted MRI, a new study concludes. Still, only the CT results correlated with severity on the stroke score scales.May 31, 2005CTCT coronary calcium results vary by scanner, body typeAttenuation values in coronary calcium scoring can vary significantly depending on the scanner, and even by patient body type, according to a new study in Radiology based on nearly 10,000 participants in two major trials. Fortunately, the researchers proposed a potential solution in the form of calibration phantoms that could improve accuracy in diagnosis and follow-up.May 30, 2005CTMidwest weighs incremental Medicare gain for VCConsidering the dim prospects for quick action on a U.S. Centers for Medicare and Medicaid Services national coverage decision that would cover virtual colonoscopy as a cancer screening option, the efforts of a few local carriers represent progress of a sort for virtual colonoscopy.May 25, 2005CTVC, colonoscopy not optimal in patients with diverticular diseaseIn a newly published study, Dr. Marc Gollub and colleagues from the Memorial Sloan-Kettering Cancer Center in New York City confirm that elastin deposition associated with diverticular disease narrows the colonic lumen significantly, and also confounds virtual colonoscopy evaluation.May 24, 2005CTCTA seen as accurate complement to invasive angiographyMove over angiography. A study to be published this week in the Journal of the American Medical Association concludes that 16-slice multidetector-row CT angiography, while not a fully developed technology, is a highly accurate complement to invasive coronary angiography.May 23, 2005Previous PagePage 207 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
