October 31, 2013 -- The combination of a novel, operator-independent ultrasound therapy device and tissue-type plasminogen activator (tPA) therapy may be able to increase the rate of artery recanalization in patients with ischemic stroke, according to a study published online October 24 in Stroke.
PET/CT dominates diverse hybrid imaging market
October 30, 2013 -- In Western Europe during 2012, there were 577 providers of PET and/or PET/CT, of which 18 were mobile, and PET/CT accounted for 92% of the installed systems, according to new market research presented last week at the European Association of Nuclear Medicine annual congress, held in Lyon, France.
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. This is nowhere more evident than in this year's Minnies awards, where candidates related to CT won many of the categories.
AJR: Skipped breast screenings increase cancer risk
October 29, 2013 -- When women skip a mammography screening exam -- even for just one year -- their risk of late-stage cancer increases, according to a new study published in the November issue of the American Journal of Roentgenology.
PET/MRI could be alternative to PET/CT for liver lesions
October 28, 2013 -- PET/MRI is more than adequate in characterizing liver lesions and provides greater lesion conspicuity than PET/CT, offering clinicians a powerful alternative for oncology imaging, according to a German study published in the November issue of the European Journal of Radiology.
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.
