Eric Barnes[email protected]CTStudy maps CT radiation doses in 100K examsHave you ever wondered how your facility's CT radiation dose levels stack up against those of other institutions? A study in Radiology describes the experience of researchers from five University of California campuses who measured dose in nearly 86,000 adults and children undergoing common CT scans.July 26, 2015UltrasoundSoftware aims for realism in echocardiographyA new echocardiography software package released this month analyzes cardiac structure and function pixel by pixel to render detailed functional 3D images that could speed up diagnosis and reduce the number of exams needed in patients undergoing cardiac workups.July 26, 2015CT4D parathyroid CT sorts out lesion typesCT scans with 4D image reconstruction can separate parathyroid adenomas and hyperplastic lesions into three distinct lesion types based on enhancement patterns, alerting surgeons to the variations they will find, according to a study in Radiology. The findings also indicate that a three-phase scanning protocol is still needed, the authors believe.July 23, 2015CTMGH saves money and time printing 3D heartsResearchers at Massachusetts General Hospital (MGH) in Boston say that having a 3D rapid prototyping printer in the cardiac imaging department is a potential boon for procedure planning and patient education -- and it doesn't break the bank.July 16, 2015CTAAPM: Fetal CT dose calculator offers easy, accurate estimatesA new technique that calculates fetal dose from CT scans given to pregnant women is accurate and easy to perform, according to a study presented at this week's American Association of Physicists in Medicine (AAPM) 2015 annual meeting in Anaheim, CA.July 14, 2015CTGender surprise in stimulant study; cocaine damage heals; radiologists order appropriatelyJuly 13, 2015CTA (myocardial) bridge too far: CT vs. IVUS in the heartMultidetector-row CT should be considered the noninvasive gold standard when evaluating myocardial bridge abnormalities, owing to its anatomic accuracy. But there are important things CT doesn't see that intravascular ultrasound (IVUS) does, according to new research from Stanford University.July 7, 2015CTCoronary calcium CT scans predict mortalityA simple coronary calcium CT scan can be used to predict death in asymptomatic individuals for as long as 15 years after the scan, according to a new study of nearly 10,000 people, published in the July 7 issue of the Annals of Internal Medicine.July 6, 2015CTDoes low-level radiation really cause cancer?The scientific theory that links low levels of radiation to cancer incidence is deeply flawed and cannot be used as a model to predict excess cancer incidence, researchers argue in a paper published in Technology in Cancer Research and Treatment.July 1, 2015CTCT radiation dose levels in clinical trial surprise researchersA group of researchers studying the use of CT for kidney stones were surprised by the radiation dose levels they discovered in their multicenter clinical study. Not only were many doses too high, they also varied widely between centers, concludes a research letter published June 29 in JAMA Internal Medicine.June 28, 2015Previous PagePage 33 of 258Next PageTop StoriesMRIMRI, PET reveal distinct brain changes in loneliness and social isolationPrior studies frequently have used the terms interchangeably and applied measures designed for one construct when investigating the other.MRIPodcast: Hospital accreditation isn’t a safety net for MRIAISIIM-CAIMI program chairs talk medical imaging AI's evolutionCTLDCT predicts vertebral fracture risk in heavy smokersSponsor ContentFREE webinar: find your imaging capacity
