ARRS: Sharing info leads to dramatic CT dose reduction
April 22, 2015 -- TORONTO - Reducing unnecessary variation in CT radiation dose can be done fairly easily by getting radiology professionals together to share best practices, even across a healthcare system as large as the University of California's, according to a presentation at the annual American Roentgen Ray Society (ARRS) meeting.
Radiation dose issues climb agenda in Middle East
April 22, 2015 -- New research from Dubai, United Arab Emirates, reveals how the region is targeting ever-optimized dosage in imaging and how dose awareness is becoming of greater importance within the radiological community.
ARRS: Cancer diagnosis leads smokers to quit
April 21, 2015 -- Smokers diagnosed with cancer are more likely to quit smoking than other smokers, according to a new study by the American Cancer Society presented at this week's American Roentgen Ray Society (ARRS) annual meeting in Toronto.
UC Davis group wins CT lung nodule surveillance grant
April 17, 2015 -- Researchers from the University of California, Davis have received $2.3 million to run a new study aimed at improving surveillance practices for patients with small, low-risk lung nodules. 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.
