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. Other important elements of reducing exposure are more assertive radiologists and increased use of healthcare IT.
Tackling the challenge of setting up a 3D lab: Part 2
February 13, 2012 -- In the scond part of our series on how to set up a 3D laboratory, AuntMinnie.com provides coverage of Dr. Eliot Siegel's suggestions on topics such as dealing with billing and coding issues and navigating the pitfalls of 3D labs.
Ultralow-dose CT enables PET correction
February 13, 2012 -- The use of ultralow-dose CT scans for attenuation correction and respiratory gating of PET scans is feasible, concluded a recent study published in Physics in Medicine and Biology. Doses an order of magnitude lower than existing low-dose CT protocols on PET/CT scanners were achieved.
Post-op rad therapy unneeded for elderly lung cancer patients
February 13, 2012 -- Patients who have undergone surgery to resect stage III non-small cell lung cancer with N2 lymph node involvement may not need postoperative radiation therapy if they are older than 65, as the treatment doesn't help survival, according to an article published online February 13 in Cancer.
