PiB-PET shows more beta amyloid after traumatic brain injury November 12, 2013 -- British researchers are using PET imaging with the Pittsburgh Compound B (PiB) radiopharmaceutical to show -- for the first time -- increased beta-amyloid deposits in cortical gray matter and striatum regions following traumatic brain injury.
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.
PiB-PET scans show link between poor sleep and Alzheimer's October 22, 2013 -- PET scans using the Pittsburgh Compound B (PiB) radiopharmaceutical have shown a potential link between poor sleep and greater beta-amyloid accumulation, which could lead to Alzheimer's disease in older adults, according to a study published online October 21 in JAMA Neurology.
PET shows link between arterial stiffness and dementia October 17, 2013 -- PET scans show that elderly people with hardening of the arteries are more likely to have beta-amyloid plaque in the brain, even if they show no signs of dementia or Alzheimer's disease, according to a study published online October 16 in Neurology.
Better training key to unlocking molecular imaging's potential October 11, 2013 -- Molecular imaging has vast potential to improve healthcare in the coming years by allowing more directed, personalized therapy. But molecular imaging's contribution may be limited until more imaging specialists are trained to interpret scans acquired with the new types of tracers being developed.
ICER: Evidence of beta-amyloid PET's efficacy still lacking October 1, 2013 -- A review of clinical studies on the efficacy of beta-amyloid PET for Alzheimer's disease has led the Institute for Clinical and Economic Review (ICER) to conclude that evidence supporting the scans is still lacking, according to an article published online September 30 in JAMA Internal Medicine.
PET/MRI shows growing edge over PET/CT in oncology September 17, 2013 -- FDG-PET/MRI more accurately evaluated and more often changed the management of patients with various forms of cancer in a comparison with PET/CT, according to preliminary research published online September 5 in Radiology.
