3D knee model reveals ACL tear same in men, women
April 18, 2018 -- When researchers recreated an anterior cruciate ligament (ACL) rupture using 3D models based on MR scans of knees, they found no mechanistic differences in the injury between men and women, according to an article published online April 18 in the American Journal of Sports Medicine.  Discuss
MRI for knee pain adds cost with negligible benefit
April 18, 2018 -- The early diagnosis of an abnormality in any part of the body is often seen as a way to speed recovery. Having an MRI scan for knee pain when symptoms begin, however, hikes healthcare costs with no great benefit to the patient's quality of life, according to a study published online April 17 in Radiology.  Discuss
How prevalent are incidental thyroid nodules on CT?
April 18, 2018 -- Incidental thyroid nodules on CT lung screening scans may be more common than you think, according to an analysis of data from the National Lung Screening Trial (NLST). Researchers found more nodules requiring workup than were originally reported by NLST readers.  Discuss
Report tallies growth in imaging scanners in Canada
April 17, 2018 -- The number of MRI scanners in operation in Canada has grown 65% over the past 10 years, while the number of CT scanners has increased 35% over the same period, according to a new report published by the nonprofit Canadian Agency for Drugs and Technologies in Health.  Discuss
Has standardized testing ruined radiology's board exam?
April 17, 2018 -- The radiology board certification exam's shift from an oral exam to a standardized test with multiple-choice questions could mean that the exam is less accurate in evaluating which candidates are ready and competent to become radiologists, according to a new article in the Journal of the American College of Radiology.  Discuss
Sonographers exposed to radiation from MPI patients
April 17, 2018 -- A new study found that sonographers who performed cardiac ultrasound studies on patients who received nuclear myocardial perfusion imaging (MPI) scans were exposed to residual radiation from the patients. While the radiation levels were low, the researchers advised that sonographers modify their scanning techniques.  Discuss
New Alzheimer's definition relies on imaging biomarkers
April 17, 2018 -- New research guidelines for classifying whether individuals have Alzheimer's disease rely heavily on the use of biomarkers from imaging scans. The new framework was published in the April issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association.  Discuss
How can unnecessary ABUS recalls be avoided?
April 16, 2018 -- Automated breast ultrasound (ABUS) can yield lower recall rates than handheld ultrasound, but unnecessary recalls still occur -- and it's important to find ways to reduce them, according to research presented at the recent American Institute of Ultrasound in Medicine annual meeting in New York City.  Discuss
