Eric Barnes[email protected]Nuclear MedicineAdenosine stress DECT equivalent to SPECT, MRIA new power combo consisting of adenosine stress and dual-energy CT (DECT) is delivering diagnostic accuracy equivalent to stress/rest cardiac MRI and nuclear perfusion (SPECT) for detecting perfusion defects, according to research presented at the American Heart Association meeting in New Orleans.November 20, 2008CTMedCAC panel members question VC's effectivenessVirtual colonoscopy may have been dealt a setback this week after members of a U.S. government panel expressed doubts about the technology. Panel members charged with recommending whether VC should receive Medicare reimbursement said there was incomplete evidence of VC's cost-effectiveness and overall benefit as a screening tool for colorectal cancer.November 19, 2008CTNavajo Nation gets remote virtual colonoscopy screeningRecruited to establish a remote virtual colonoscopy service for the largely underserved rural population of Navajo Nation, Dr. Arnold Friedman learned that determination, patience, and a dedicated onsite staff were important allies in delivering state-of-the-art colon cancer screening services.November 17, 2008Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderNovember 16, 2008AIResearchers cut false positives in lung CADOne of the thorniest challenges in computer-aided detection (CAD) is the high rate of false-positive detections, a number that generally rises in tandem with the sensitivity of the CAD algorithm. University of Tokyo researchers recently set out to develop a new false-positive reduction method based on dual classifiers for juxtapleural and nonpleural nodules.November 9, 2008CTPrior hysterectomy complicates optical colonoscopyIn a study with important implications for colon cancer screening, Pennsylvania researchers found that both female gender and prior hysterectomy were associated with failed colonoscopy. Dr. Hanna Zafar discussed the results at last week's International Symposium on Virtual Colonoscopy in Boston.November 6, 2008CTAuntMinnie.com Virtual Colonoscopy InsiderNovember 3, 2008CTModel finds small polyp surveillance safe, cost-effectiveA new model analysis concludes that surveillance of small (6- to 9-mm) colorectal polyps is both safe and cost-effective compared to immediate polypectomy, which suffers from relatively high costs, rare complications, and above all a low yield for colorectal cancer in lesions smaller than 10 mm in diameter.November 3, 2008Image ProcessingDual-energy VC makes tagged materials disappearBOSTON - Researchers in Jerusalem are pushing the envelope with a novel dual-energy CT scanner and software combination that detects fecal residue tagged with barium and iodine, removing them from virtual colonoscopy images and making them easier to read.October 28, 2008CTGastroenterologists embrace VC screening, with caveatsBOSTON - Monday's talk at the International Symposium on Virtual Colonoscopy by AGA Institute president Dr. Nicholas LaRusso seemed to underscore the significance of a growing collaboration between gastroenterologists and radiologists on the issue of VC screening.October 27, 2008Previous PagePage 154 of 258Next PageTop StoriesWomens ImagingExperts, research highlight prevalence of remote breast imagingExperts and recent studies highlight the prevalence of remote breast imaging since COVID-19.UltrasoundAblation procedures cure thyroid disorders in older patientsPractice ManagementNYU researcher's new book explores how imaging is 'changing our world'Womens ImagingMirai shows promise for detecting interval breast cancersSponsor ContentJoin Us!
