Eric Barnes[email protected]Nuclear MedicineMore PET/CT lung masses seen with hardware-based fusionTwo new studies underscore the superiority of PET/CT for imaging lung lesions compared to either modality alone. The first found that different fusion methods produce substantially different results, while the second found that PET/CT has higher sensitivity, specificity, and positive and negative predictive values than either modality alone for detecting lung metastases.April 25, 2005CTGood study/bad study: VC experts seek keys to successVirtual colonoscopy has shown that it can reliably detect significant lesions of the colon and rectum. Two recent editorials, however, contemplate the myriad details that constitute a virtual colonoscopy protocol, and the ways in which minor differences in methodology can affect results in major ways.April 19, 2005CTEuropean screening trial sees lower lung cancer ratesEuropean radiologists, like their U.S. counterparts, have embarked on new efforts to answer the very long-term question of whether CT lung cancer screening and intervention in smokers can reduce mortality. Researchers from the Netherlands recently presented preliminary results from the Nelson trial, which is screening current and former smokers with MDCT and also includes an unscreened control group.April 17, 2005CTVirtual colonoscopy: Ready already for those who know howIs virtual colonoscopy ready for routine clinical use? It depends on who's doing it and how, according to Dr. Andrik Aschoff. At the recent 2005 European Congress of Radiology (ECR) in Vienna, he discussed the state of virtual colonoscopy today, and explored the often quirky relationship between radiologists, protocols, and results.April 14, 2005CTZ-axis modulation cuts VC dose, keeps image quality highScreening asymptomatic patients means justifying the radiation dose, and in recent years virtual colonoscopy practitioners have strived to ramp the dose downward, with an eye on finding the dose levels where noise levels and accuracy might begin to suffer. Researchers from Germany found that adding dedicated z-axis modulation could cut the dose, while keeping image quality high.April 11, 2005CTAuntMinnie.com Virtual Colonoscopy Radiology InsiderApril 10, 2005CTVC with contrast finds more extracolonic troubleAmong symptomatic older patients, virtual colonoscopy found more extracolonic abnormalities with IV contrast than without, according to a study presented at the 2005 European Congress of Radiology (ECR) in Vienna.April 10, 2005CTScores of detector rows bring opportunities, challenges to CT imagingThe latest-generation multidetector-row CT scanners are bringing stunning high-resolution images to daily clinical practice, but improved spatial resolution does exact a price -- in higher image noise or markedly increased radiation dose. However, a little creativity can yield solutions for some of the toughest challenges, according to a noted CT expert.April 7, 2005CTAuntMinnie.com CT Radiology InsiderApril 3, 2005CTSenate hears testimony on virtual colonoscopyAt a recent U.S. Senate Cancer Coalition hearing, a senator and several colon cancer screening experts spoke of the need to increase screening compliance, and about the role of virtual colonoscopy in those efforts.March 27, 2005Previous PagePage 209 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
