Normal tissue enhancement on breast MR predicts cancer risk
May 12, 2015 -- Contrast enhancement of normal tissue on breast MRI scans is more effective than tissue density as an imaging biomarker of breast cancer and could make existing risk models more accurate, according to a new study published online May 12 in Radiology.
Prescan review slashes inpatient use of PET/CT
May 12, 2015 -- A New Jersey hospital was able to slash by more than half the number of inpatient pulmonary PET/CT scans being performed by having its nuclear medicine department act as a gatekeeper for exam orders, according to a study presented at the recent American Roentgen Ray Society annual meeting.

CTA protocol slashes radiation dose tenfold in aortic disease
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. The finding sheds light on an increasingly consumer-driven healthcare environment, researchers from the Mayo Clinic in Rochester, MN, wrote.
New CT-based liver segmentation tool proves fast and accurate
May 6, 2015 -- Liver segmentation, used to obtain liver volumes when planning for major interventions, can be automated without loss of accuracy compared to manual measurements, cutting procedure time by more than half, according to a new study in Academic Radiology.
