320-row CT cuts pediatric radiation dose versus 64-slice imaging April 30, 2012 -- Pediatric radiation dose was cut by as much as half for some clinical applications by swapping 64-detector-row CT for 320-detector-row scanning, according to researchers from Cincinnati Children's Hospital Medical Center. The study indicates that advances in CT technology can be successfully used to cut pediatric radiation dose.
Leaders in Imaging: A conversation with Dr. Cheri Canon April 27, 2012 -- In this new Leaders in Imaging installment, we spoke with Dr. Cheri Canon, chair of radiology at the University of Alabama at Birmingham, about the American College of Radiology's Radiology Leadership Institute (RLI). RLI is planning an inaugural event in July at Northwestern University.
Study shows less contrast still performs well in cardiac MRI April 27, 2012 -- Italian researchers have found that one dose of gadobutrol appears to be just as effective as a double dose of gadopentetate dimeglumine for detecting late enhancement in cardiac MRI cases, potentially reducing possible adverse effects from contrast use.
MICI survey finds low confidence in Medicare payment rates April 26, 2012 -- Although radiology administrators are confident that over the next six months their facilities will grow in procedure volume and as a profit center, they're not so sure they'll receive adequate reimbursement from Medicare for these services, according to new results from the Medical Imaging Confidence Index (MICI).
IAEA: Doctors don't always follow guidelines for pediatric CT April 26, 2012 -- As indicated by the increasing use of CT in pediatric patients worldwide, clinicians are not always following appropriate criteria when using the modality to scan these patients, according to a study in the May issue of the American Journal of Roentgenology.
PET/CT locates infection in patients with implantable cardiac devices April 26, 2012 -- FDG-PET/CT can help differentiate between infection and postoperative inflammation in patients with cardiovascular implantable electronic devices and direct physicians to more appropriate treatment, according to a study published in the May issue of the Journal of the American College of Cardiology.
NEJM: Low-dose CT good enough to diagnose appendicitis April 25, 2012 -- Low-dose CT is nearly equivalent to the standard-dose scan for diagnosing appendicitis, and it's accurate enough to serve as a first-line diagnostic modality while delivering less than one-fourth the radiation dose of full-strength CT, researchers report in a study published in the April 26 New England Journal of Medicine.
Mammography screening for younger women: Just do it April 25, 2012 -- Screening younger women for breast cancer catches tumors at an earlier stage and smaller size, and it also finds high-risk lesions in time for treatment, reducing a woman's subsequent risk, according to a study published in the May issue of the American Journal of Roentgenology.
Percutaneous cholecystostomy deemed safe for patients over 80 April 25, 2012 -- Patients in their 80s can tolerate percutaneous cholecystostomy, with or without subsequent surgery or related procedures, just as well as younger patients, according to a new report from the University of California, San Francisco and the San Francisco Veterans Affairs Medical Center.
AAN: DaTscan SPECT tracer changes Parkinson's treatment April 24, 2012 -- Results from a randomized clinical trial being presented at this week's American Academy of Neurology (AAN) meeting suggest that the SPECT radiopharmaceutical DaTscan can help clinicians distinguish between tremors due to Parkinson's disease and non-Parkinsonian essential tremor, expediting appropriate treatment.
