Eric Barnes[email protected]CTProtocol tops scanner model in determining CTA doseA study in the May American Journal of Roentgenology compared three CT scanners at coronary CT angiography (CTA). The results showed that protocols were more important than scanner model in determining dose, with effective dose reductions of 40% to 50% achieved by reducing tube current from 120 to 100 kV.May 4, 2011CT3D CT printing simplifies neurosurgical planningFor planning neurosurgery with CT images, radiologists in Hawaii have begun using automated 3D models to provide surgeons and patients with information that can't be replicated on a flat computer monitor. A demonstration project this week at the American Roentgen Ray Society meeting is showing how it's done.May 3, 2011CTLow risk to fetus seen in most CT scansYou don't necessarily need to rule out CT scans of pregnant patients if appropriate precautions are taken, according to a study in the May issue of the American Journal of Roentgenology. The study found that fetal radiation dose is generally low and has been dropping with newer generations of scanners.May 1, 2011Digital X-RayResearchers suggest caution with contrast use in womenWomen undergoing conventional angiography have a 62% higher risk of kidney problems after contrast than a demographically similar group of men, researchers found in an analysis of more than 1,000 patients that will be presented at the National Kidney Foundation's Spring Clinical Meetings this week in Las Vegas.April 27, 2011CTVC ready for universal use, meta-analysis showsIn a meta-analysis of more than 10,000 patients scanned on five continents, virtual colonoscopy detected almost 95% of colorectal cancers -- and 100% when proper tagging and cleansing methods were used, according to a study published in the May edition of Radiology.April 26, 2011CTMRI still no match for CT in cystic fibrosisThe key imaging components of cystic fibrosis of the lungs are bronchiectasis and air trapping. For evaluating both, CT remains far and away the superior imaging modality despite radiation concerns, and despite recent improvements in MRI techniques, according to a study from Italy and the Netherlands.April 25, 2011CTU.S. legislation would set up lung screening programDemocrats and Republicans have joined forces to introduce the Lung Cancer Mortality Reduction Act of 2011, legislation that would include the launch of a pilot lung screening program.April 21, 2011CTCalcium boosts death rate in patients with family historyPatients with a family history of coronary heart disease should pay heed to their coronary artery calcium scores to boost their chances of living longer, says a new study of more than 40,000 patients.April 20, 2011CTFirst-reader CAD equals conventional VC CAD paradigmComputer-aided detection (CAD) used concurrently with the first reading of a virtual colonoscopy study offers diagnostic performance similar to that of the conventional interpretation paradigm, in which CAD is used as a second reader following unassisted interpretation by the radiologist, say researchers in Turin, Italy.April 11, 2011CTItalian VC surveillance patients won't waitIn results that run counter to a U.S. center's experience, Italian patients undergoing virtual colonoscopy screening won't wait three years for surveillance and follow-up of small polyps as an alternative to colonoscopy, according to a new study from the University of Pisa.April 10, 2011Previous PagePage 104 of 258Next PageTop StoriesMRIPI-RADS v2.1 is 'highly sensitive' for prostate cancer detection on MRIPI-RADS v2.1 was developed by the ACR and the European Society of Urogenital Radiology (ESUR) and released in 2019.UltrasoundqHDMI differentiates radial scars from invasive breast cancerInterventionalLung biopsy before surgery linked to cancer recurrenceCTAbnormal CT-FFR results translate to up to 7 years of cardiovascular riskSponsor ContentRegister Now: Breaking Barriers in Breast Imaging Webinar
