CT viable option to exclude cervical spine injury in obtunded patients February 15, 2012 -- Using CT for mentally compromised trauma patients to exclude cervical spine injury is a viable alternative to cervical collar immobilization and reduces unnecessary patient immobilization, according to research presented at last week's American Academy of Orthopaedic Surgeons annual meeting.
Low reader confidence in CAD hinders results in MRA screening February 15, 2012 -- Computer-aided detection (CAD) technology can be a valuable tool for improving the detection of cerebral aneurysms, but researchers from the University of Tokyo found that a lack of reader confidence in CAD findings can impede its effectiveness when used for MR angiography (MRA) screening.
FDDNP-PET helps predict Alzheimer's progression February 14, 2012 -- Using PET to image the radiopharmaceutical FDDNP in the brain, California researchers are showing how the accumulation of abnormal protein deposits is associated with Alzheimer's disease progression, according to a study in the February Archives of Neurology.
Obama's 2013 budget mandates imaging preauthorization February 14, 2012 -- President Barack Obama's proposed 2013 U.S. budget would save Medicare and Medicaid nearly $5 billion over the next decade -- in part by requiring prior authorization for advanced diagnostic imaging services.
FDG-PET/CT helps manage retinoblastoma cancer February 14, 2012 -- Optic nerve uptake at baseline on an FDG-PET/CT scan and response after neoadjuvant chemotherapy are strong predictors of event-free and overall survival for young children with stage III retinoblastoma, according to a study in the February issue of the Journal of Nuclear Medicine.
MRI shows benefits of Mediterranean diet on the brain February 14, 2012 -- The fabled Mediterranean diet may be good for your brain as well as your waistline. MRI has revealed that people who adhere to the diet have reduced brain white-matter hyperintensity volume, thus reducing their chance of chronic small-vessel damage, according to a study in the February issue of Archives of Neurology.
Clinician awareness key to reducing imaging radiation risk February 13, 2012 -- Educating referring physicians about the cancer risks from imaging exams is key to reducing patient exposure to medical radiation, according to an article in CA: A Cancer Journal for Clinicians.
