Winners of 2013 Minnies highlight CT's resilience
October 30, 2013 -- CT remains the workhorse medical imaging technology that's still making headlines some four decades after Sir Godfrey Hounsfield figured out a way to put EMI's Beatles royalties to work.

FDA approves GE's Vizamyl PET radiotracer for dementia
October 25, 2013 -- U.S. physicians looking to detect early signs of Alzheimer's disease now have a second tool in their arsenal with the U.S. Food and Drug Administration's approval of Vizamyl (flutemetamol F-18 injection), a radiopharmaceutical from GE Healthcare for use with PET imaging of the brain in adults being evaluated for Alzheimer's and dementia.
Vendor-neutral archives: Strategy for health info exchange
October 25, 2013 -- Today's health data are fragmented and coveted. Patient medical information and assets (medical images, medications, etc.) are not patient-centric, but more often health system-centric. That can change thanks to vendor-neutral archives, according to Ifetayo Freeman of Ascendian Healthcare Consulting.
NEJM: Urologist self-referral equals IMRT overuse
October 24, 2013 -- Allowing urologists to self-refer patients for intensity-modulated radiation therapy (IMRT) treatments contributes to overuse of this expensive therapy, according to new research published in the New England Journal of Medicine.
Small-group focus boosts radiology clerkship
October 24, 2013 -- Educators in Boston have made their radiology clerkship more practical and effective for medical students by starting them early in the third year and focusing on small-group learning rather than large plenary sessions, according to a report in the Journal of the American College of Radiology.
Study: CT shows promise as a breast density assessment tool
October 24, 2013 -- Breast density readings taken at CT are consistent with those acquired at mammography, according to a new study published online in Radiology.
