Eric Barnes[email protected]Advanced VisualizationScreening is best reserved for those expected to live longerPatients signing up for breast or colon cancer screening should have a minimum remaining life expectancy of at least 10 years to boost the chances of benefiting from the exams and overcoming their inherent risks, say researchers from the University of California, San Francisco in an article in BMJ.January 9, 2013Clinical NewsLow-dose CT raises coronary calcium scores; IR corrects themLow-dose coronary artery calcium (CAC) scores are reliable if iterative reconstruction (IR) is applied to the CT data, according to research presented at RSNA 2012. Dutch researchers found that the technology ensures the accuracy of CAC scores that would otherwise be higher and less predictable than the results of higher-dose CT scans.January 1, 2013Clinical NewsAutomated tube current selection keeps CCTA quality, cuts doseUsing software that automatically selects the tube current modulation significantly reduces the radiation dose in coronary CT angiography (CCTA) compared with manual kV selection based on patient size, researchers from South Korea reported at RSNA 2012.December 26, 2012Clinical NewsMBIR finds same nodules as ASIR, at fraction of doseSecond-generation iterative reconstruction software doesn't necessarily improve radiologists' ability to detect lung nodules compared to earlier versions. But the new software permits the same lesion detection power at greatly reduced CT radiation doses, according to a study presented at last month's RSNA 2012 meeting in Chicago.December 20, 2012Clinical NewsCT screening finds fast-growing lung cancersThree-fourths of lung cancers detected through CT screening are aggressive, according to the results of a study in the December 4 Annals of Internal Medicine that boosts the value of CT screening while tamping down fears of overdiagnosis.December 6, 2012Clinical NewsTime to ditch the chest x-ray, Norwegians concludeCHICAGO - If cost isn't an issue -- and that's a big if -- it's time to say goodbye to chest radiography, say researchers from Norway who compared chest x-ray to ultralow-dose CT. Results were presented at the 2012 RSNA meeting.December 2, 2012Clinical NewsStudy: CCTA technique skips the breath-holdPatients undergoing coronary CT angiography (CCTA) no longer have to hold their breath when doing so is challenging for them. CCTA images acquired on a 320-detector-row scanner using a free-breathing technique are similar to the traditional breath-hold images.November 21, 2012Cardiac ImagingAuntMinnieEurope.com Cardiac Imaging InsiderNovember 12, 2012Clinical NewsNew algorithm can boost CTA resolution in obese patientsA new reconstruction algorithm increases the accuracy and diagnostic performance of dual-source CT angiography (CTA) by raising the temporal resolution of images acquired at slow gantry rotation speeds, making it suitable for obese patients, a German-U.S. research project has found.November 12, 2012Residents/FellowsSocial networking blunders can jeopardize traineeshipsWhat you post on social media can hurt you, especially if you're applying for a traineeship, according to a new BMJ study that surveyed personnel in charge of reviewing applications from potential medical residents and students.November 8, 2012Previous PagePage 31 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
