JAMA: Early imaging questionable for older adults with back pain
March 18, 2015 -- Older adults who have spine imaging within six weeks after an initial visit for care for lower back pain were no better off the following year than similar patients who did not undergo early imaging, according to a study published in the March 17 issue of the Journal of the American Medical Association.
ACC: PET/CT trumps SPECT for cardiac studies
March 17, 2015 -- Researchers from Utah found that PET/CT is far superior to SPECT for diagnosing myocardial ischemia, with higher sensitivity at a lower radiation dose, according to a paper presented on Sunday at the American College of Cardiology (ACC) meeting in San Diego. PET/CT in particular far outstripped SPECT in determining that patients were free of cardiac disease.
NCoBC: Mammography techs play crucial role in women's health
March 17, 2015 -- The evolution of breast imaging has made mammography technologists much more than just "button pushers," with their role evolving to include not only more patient interaction but also more education and training, according to a March 16 presentation at the National Consortium of Breast Centers (NCoBC) meeting in Las Vegas.
ACC: CCTA sharpens diagnosis, targets intervention
March 17, 2015 -- More accurate diagnosis using coronary CT angiography (CCTA) in chest-pain patients will reduce the risk of heart attack and hone treatment, according to a new study from Scotland that was presented at this week's American College of Cardiology (ACC) annual meeting in San Diego. Researchers found that patients with suspected angina benefited from clearer results after undergoing CCTA.
Adults at low risk of heart disease shouldn't get screening
March 16, 2015 -- Cardiac screening shouldn't be performed on patients at low risk for coronary heart disease, as it doesn't improve patient outcomes and comes with potential harms due to false-positive results, according to a paper published on Monday in the Annals of Internal Medicine by the American College of Physicians.

MedPAC takes long view despite 1% drop in imaging volume
March 13, 2015 -- There was a 1% drop in imaging volume per Medicare beneficiary between 2012 and 2013, according to new figures released by the Medicare Payment Advisory Commission (MedPAC). But despite the decline, MedPAC is pointing out that the use of imaging services remains higher than it was a decade ago.
Technologists can affect mammogram interpretations
March 13, 2015 -- Mammogram interpretation is known to vary by patient, radiologist, and facility characteristics, but what about technologists? Do they also influence interpretation? The answer is yes, according to a new study published in the March edition of Academic Radiology.
Study links overuse of imaging for prostate, breast cancer
March 12, 2015 -- A new study published online March 12 in JAMA Oncology found that geographic regions where imaging overuse is common for prostate cancer also see high overuse rates of breast cancer imaging -- a very different type of disease. The findings indicate that imaging overuse could have a regional component, a development that might complicate efforts to reduce the phenomenon.
More T, doctor? No thanks
March 12, 2015 -- As the European market recovers from economic turmoil, cost is an ever important factor in MRI purchasing decisions, and advanced 1.5-tesla systems are likely to account for a far higher proportion of unit shipments compared with 3-tesla systems over the next five years.
