Delayed NaF-PET enhances coronary plaque detection
September 18, 2018 -- In life, timing is everything. With sodium fluoride (NaF) PET, interpreting results three hours after tracer injection instead of the customary one-hour delay improved image quality and standardized uptake values, leading to significantly better coronary plaque detection, according to a September  13 article in the Journal of Nuclear Medicine.  Discuss
PET/CT makes case for directing cervical cancer treatment
September 14, 2018 -- Can FDG-PET/CT be used to direct the treatment of locally advanced cervical cancer by determining which patients should receive more extensive chemoradiation therapy or palliative care? Maybe, but findings from a new study published online September 14 in JAMA Network Open are equivocal.  Discuss
Prostate MRI coverage varies greatly -- with many caveats
September 13, 2018 -- Insurance coverage for prostate MRI scans varies widely among private payors, requires certain conditions for reimbursement of major conditions, and does not reflect current clinical practice. Those harsh conclusions are contained in a new study published online September 11 in the Journal of the American College of Radiology.  Discuss
Research road map drives inquiry into gadolinium's effects
September 12, 2018 -- What's causing gadolinium retention after the use of gadolinium-based contrast agents for MRI scans? Even the most knowledgeable experts don't know for sure, but they hope to clear up some of the confusion with a new research road map unveiled September 11 in a special report published in Radiology.  Discuss
Timing of DWI-MRI predicts breast cancer response
September 11, 2018 -- Diffusion-weighted MR images acquired 12 weeks after the start of neoadjuvant chemotherapy for breast cancer may provide the best indication of how patients will respond to treatment, according to a study published online September 4 in Radiology.  Discuss
Is Medicare paying enough for MRI-compatible implants?
September 7, 2018 -- U.S. hospitals could be losing up to $400 million annually on placing MRI-compatible cardiac rhythm management devices in patients due to a discrepancy between what the devices cost and what Medicare is paying for them, according to a new report by group purchasing organization Vizient.  Discuss
Imaging modalities differ in assessing key heart metric
September 6, 2018 -- There is "substantial variability" in the way that different medical imaging modalities measure left ventricular ejection fraction, a key measure of heart function. This variation should be seriously considered before patient treatment, according to an international study published online August 31 in JAMA Network Open.  Discuss
MRI shows concussions can loosen brain's myelin
September 6, 2018 -- MR images of hockey players with concussions showed a loosening of protective myelin in the brain two weeks after the injury, even though the skaters felt fine and were declared ready to return to play, according to a study published online August 6 in Frontiers in Neurology.  Discuss
Training is paramount to achieving MRI safety
August 31, 2018 -- "With careful consideration, control, and training, imaging with MR can be a relatively innocuous experience for both patients and personnel." Those words of wisdom come from an article published online August 24 in the Journal of the American College of Radiology on how to reduce or eliminate accidents and injuries in the MRI suite.  Discuss
New protocol enables faster, cheaper cardiac MRI scans
August 30, 2018 -- Researchers have developed a rapid contrast-enhanced cardiac MRI protocol that can measure structure, function, and scarring in the heart in less than 20 minutes and at considerably lower cost than standard MRI protocols, according to results published on August 29 in the Journal of the American Heart Association.  Discuss
