Eric Barnes[email protected]Clinical NewsSharper image: 3D phase-contrast tomo shows smaller breast tumorsResearchers from Germany, France, and the University of California, Los Angeles have collaborated to produce ultrasharp 3D breast images with a technique that delivers less radiation than a mammogram, according to an article published online in the Proceedings of the National Academy of Sciences.October 25, 2012Clinical NewsNoncontrast CT may underestimate lung nodule volumeLow-dose unenhanced CT scans may underestimate the volume of smaller lung nodules compared with standard-dose contrast CT studies, creating potential problems when tracking nodules over time, wrote researchers in the October issue of the American Journal of Roentgenology.October 14, 2012Advanced VisualizationESGAR publishes consensus statement on CT colonographyThe European Society of Gastrointestinal and Abdominal Radiology (ESGAR) has published its first update on CT colonography (CTC) guidelines since 2007. Its working group on CTC has endorsed 86 statements, reaching near-complete agreement on 71 of the 86 items relating to critical practice areas affecting CTC.October 14, 2012Cardiac ImagingAuntMinnieEurope.com Cardiac Imaging InsiderSeptember 10, 2012Clinical NewsChest pain diagnosis edges toward perfusionThe use of cardiac CT for chest pain is evolving toward the use of perfusion CT imaging before intervention, according to a discussion on the triage of patients with suspected coronary artery disease.September 10, 2012Advanced Visualization2 radiographers read CTC studies as well as 1 radiologistWhen it comes to reading CT colonography (CTC) studies, a radiographer is no match for a trained radiologist. But two radiographers are another matter entirely: They were equivalent to, and maybe slightly better than, a single radiologist, according to a new Dutch study in Radiology.September 9, 2012Advanced VisualizationCAD-first scheme speeds virtual colonoscopy readsDoes virtual colonoscopy need the kind of speed that only computer-aided detection (CAD) can provide? An advanced reading technique cut interpretation times to a minimum by using CAD first for polyp detection -- followed by the radiologist, who looked only at CAD results, according to a new study from Europe and the U.S. in European Radiology.August 30, 2012Clinical NewsESC: 320-detector-row CTA plus perfusion helps triage patientsA two-step heart test consisting of 320-detector-row CT angiography (CTA) followed by CT perfusion helps separate patients who need invasive angiography from those who do not, according to results of the international CORE 320 study presented on Monday at the European Society of Cardiology (ESC) annual meeting in Munich.August 27, 2012Clinical NewsESC: Fractional flow reserve CT finds vessels causing ischemiaFractional flow reserve CT in patients with significant stenosis can distinguish those with coronary artery disease who need revascularization from those who don't, concluded a study presented this week at the European Society of Cardiology (ESC) meeting in Munich and published concurrently in the Journal of the American Medical Association.August 26, 2012Clinical NewsCCTA determines which patients benefit from revascularizationCoronary CT angiography (CCTA) alone can determine the need for invasive cardiac intervention, according to a multicenter study of more than 15,000 patients presented on Sunday at the European Society of Cardiology meeting in Munich. In patients with high-risk heart disease at CT, revascularization boosted survival, while revascularization had no effect on those considered low risk.August 26, 2012Previous PagePage 32 of 59Next PageTop StoriesMolecular ImagingUnfilled vacancies and disparities persist in nuclear medicineNuclear medicine specialists have high career satisfaction, but unfilled vacancies and career disparities persist, finds a workforce survey by the European Association of Nuclear Medicine (EANM).Molecular ImagingPET develops key clinical role in neuroendocrine tumorsMolecular ImagingPET/CT visualizes complications in patients on hemodialysisCTAll roads lead to outsourcingMRIZonal segmentation with AI shows promise in prostate cancer
