Eric Barnes[email protected]CTDECT cuts tests as a one-stop myocardial, coronary artery examA single dual-energy CT (DECT) exam can provide an accurate, integrative analysis of coronary artery morphology and myocardial blood supply, according to researchers from the Medical University of South Carolina. The study highlights the potential of DECT as a one-stop shop.August 9, 2009CTDual-source coronary CTA has advantages over 64-sliceEven in patients with well-controlled heart rates, dual-source coronary CT angiography (CTA) delivers significantly higher specificity and accuracy per coronary segment compared to 64-detector-row CTA, concludes a new study from Switzerland.August 6, 2009CTLower-kilovoltage coronary CTA maintains image qualityIn a study that included all but the heaviest cardiac imaging patients, European and Japanese researchers were able to cut radiation dose by 31% in coronary CT angiography (CTA) studies by reducing the kilovoltage from 120 kV to 100 kV, with no difference in image quality.August 4, 2009Image ProcessingSophisticated electronic bowel cleansing boosts polyp detectionA new suite of investigational image-processing tools known as structure-analysis cleansing is improving the results of virtual colonoscopy scans performed after limited bowel preparation. The goal is to make virtual colonoscopy easier on patients and persuade them to get screened for colorectal cancer.August 2, 2009Digital X-RayCAD finds breast cancers missed at CR mammographyComputer-aided detection (CAD) was highly sensitive in picking up cancers that computed radiography (CR)-based mammography had missed, according to a multicenter study presented at the Computer Assisted Radiology and Surgery meeting.July 30, 2009CTAuntMinnie.com Virtual Colonoscopy InsiderJuly 27, 2009CTTopographical height mapping moves mountains in polyp detectionA little geography goes a long way in computer-aided detection of virtual colonoscopy. Researchers from the National Institutes of Health and Old Dominion University have found a novel way to use topographical height mapping for polyp detection and measurement.July 26, 2009CTContrast-induced nephropathy: Much ado about nothing?Despite the recent controversy over contrast media and contrast-induced nephropathy (CIN), a review of clinical studies indicates a distinct lack of serious adverse events resulting from CIN.July 26, 2009CTAuntMinnie.com CT InsiderJuly 22, 2009CTZero calcium means good outcomes, even with undetected plaquesPatients with coronary artery plaques -- soft, mixed, or otherwise -- that go undetected in a calcium scan still have a good prognosis, according to a new study presented at last week's Society of Cardiovascular Computed Tomography meeting in Orlando, FL.July 22, 2009Previous PagePage 143 of 258Next PageTop StoriesNuclear MedicineLLMs rapidly evolving in nuclear medicineLarge language models (LLMs) are widely used to handle the large volume of text data generated in nuclear medicine.MRIDWI with fat correction identifies liver scarring in MASLD patientsUltrasoundGhost scans problematic in POCUS trauma examsMolecular ImagingPSMA-PET may require selective use to be cost-effectiveSponsor ContentJoin Us!
