New ACR award recognizes excellence in radiology May 31, 2013 -- You've heard all about the need for quality and excellence in radiology, but the concept means different things to different people. The American College of Radiology (ACR) is hoping to clarify what quality means with its Diagnostic Imaging Centers of Excellence award, given for the first time earlier this month to two radiology facilities.
iPad comes up just short for detecting cerebral infarction May 30, 2013 -- A first-generation iPad slightly underperformed medical-grade liquid crystal displays for spotting cerebral infarction on brain CT studies, but the effect is reduced when more experienced readers are using the iPad, according to research published in the June issue of the American Journal of Roentgenology.
Contrast use spikes CT radiation dose May 30, 2013 -- The use of contrast media during CT scans significantly increases how much radiation patients absorb in amounts that vary by organ, researchers report in the June edition of the American Journal of Roentgenology. Radiologists should account for the expected dose increases when setting scanner protocols, they said.
Confusion over radiation risk could lead to inappropriate exams May 29, 2013 -- When radiologists have access to radiation exposure histories for patients, most will take them into consideration when assessing the risk of further exposure in future imaging exams, according to a new study published in the June issue of the American Journal of Roentgenology. But should they?
Plaque volume on CCTA outperforms luminal narrowing for diagnosis May 29, 2013 -- Total plaque volume at coronary CT angiography (CCTA) is a more reliable predictor of stenosis than luminal narrowing -- to the point where it could help differentiate between patients who have stenosis detected on CCTA and the smaller number with true flow-limiting lesions that need treatment, wrote researchers in the Journal of the American College of Cardiology.
Imaging groups urge CMS not to adopt FDG-PET scan limitations May 28, 2013 -- Radiology, nuclear medicine, and neuroradiology organizations are anxiously awaiting a decision from the U.S. Centers for Medicare and Medicaid Services (CMS) that would finalize its proposal to limit FDG-PET coverage to one nationally covered scan.
Imaging experts mull over color challenges May 28, 2013 -- Color images are technically difficult to deal with, creating a thorny issue that's growing as PACS broadens from radiology and cardiology to include other specialties that use color-heavy images. Medical informatics expert Dr. David Clunie discusses a recent meeting designed to provide a framework for handling color.
Clear scanner protocols can help avoid CT radiation mistakes May 27, 2013 -- CT protocols are getting more complex with each new scanner generation, challenging even the best-run radiology departments. Fortunately, a comprehensive protocol plan can minimize the fuss -- and the potential for dangerous mistakes, according to a talk at the Virtual Symposium on Radiation Safety and Computed Tomography.
Decision-support tool slashes inappropriate heart imaging May 24, 2013 -- The use of physician decision-support software based on appropriateness criteria eliminated three-fourths of inappropriate imaging exams for evaluating coronary artery disease, according to a study published online May 21 in the Journal of the American College of Cardiology.
CAD for breast MRI improves sensitivity; accuracy not so much May 24, 2013 -- Computer-aided detection (CAD) technology improves sensitivity in breast MRI for both experienced and novice readers, but it does not significantly advance overall accuracy, according to a study published in the June issue of the American Journal of Roentgenology.
