The 26-center project will begin June 1.
CT technique enables single-kidney GFR calculation April 16, 2015 -- Improvements in CT hardware and software are enabling clinicians to measure glomerular filtration rate (GFR) in a single kidney, an advancement that replaces less accurate options and permits a range of useful new diagnostic tools, according to researchers writing in Radiology.
Half of positive SPECT patients negative at CCTA April 13, 2015 -- Nearly half of all patients who test positive on SPECT myocardial perfusion imaging are found to be negative at coronary CT angiography (CCTA), calling into question the routine use of SPECT myocardial perfusion imaging, a test that has been a mainstay of the diagnostic workup of patients with a clinical suspicion of coronary artery disease.
Study finds wild price variations for head CT scans April 9, 2015 -- The price of a noncontrast head CT scan can vary more than fivefold in academic hospitals and more than tenfold in private practices across the U.S., according to a new study published online in the Journal of the American College of Radiology.
Study: It's tough complying with Calif. dose reporting law April 2, 2015 -- Compliance with California's radiation dose reporting law is difficult because dose reporting processes that rely on manual data entry are unreliable -- at least in the experience of one large institution -- according to a new study in the American Journal of Roentgenology.
AGA retreats on workup for pancreatic cysts found on imaging March 26, 2015 -- The American Gastroenterological Association (AGA) has published new guidelines for managing asymptomatic neoplastic pancreatic cysts detected incidentally during CT or MRI scans. The guidelines retreat from previous advice to follow up these lesions more aggressively, according to an article published in Gastroenterology.
Patients want information about radiation risk March 24, 2015 -- A new study published online in Radiology shows that patients want more information about medical radiation risks, but most would prefer to get it from the doctor managing their care, rather than a radiologist. This means that radiologists need to be more proactive in arming these physicians with information on radiation's risks and benefits.
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: 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.
One-fifth of middle-aged athletes risk a heart attack March 9, 2015 -- VIENNA - A new study presented at ECR 2015 reveals that 19% of middle-aged athletes are at risk of coronary events -- confirming the serious risks to asymptomatic individuals suggested in earlier U.S. studies looking at sudden cardiac death.
