May 11, 2015 -- A novel CT angiography (CTA) technique using nongated high-pitch images and iterative reconstruction delivered diagnostic scans across the board at about one-tenth the dose of standard exams, along with fewer motion artifacts and lower contrast media requirements, concludes a new study in Academic Radiology.
Rads are doing fewer double CT scans -- but nonrads aren't
May 8, 2015 -- The U.S. Centers for Medicare and Medicaid Services has worked to cut imaging costs across all modalities, and its efforts with "double" CT scans of the abdomen have been effective with radiologists, who have reduced their rates by 35% since 2001. But other physicians haven't followed suit.
Point-of-care ultrasound can assess soft-tissue neck masses

Mandatory child life counseling calms kids before MRI scans
May 7, 2015 -- A new study from Johns Hopkins Hospital found that requiring pediatric patients to undergo child life consultations prior to an MRI scan significantly reduced the need for anesthesia to keep the children from fidgeting during the exam, according to a study published online April 22 in the Journal of the American College of Radiology.
Knee MRI prices can vary almost 8-fold across the U.S.
May 6, 2015 -- The price of an outpatient noncontrast MRI scan of the knee can vary across the U.S. by almost eightfold, according to a new study in the May issue of the Journal of the American College of Radiology.
