Study shows disparities in PET access for NSCLC patients February 27, 2013 -- While PET utilization increased overall among Medicare beneficiaries with non-small cell lung cancer (NSCLC) from 1998 through 2007, long-standing disparities in access to the technology actually worsened over the same time period, according to a study published online February 15 in Radiology.
Imaging again dominates ECRI list of hospital tech issues February 21, 2013 -- For the second year in a row, topics related to medical imaging dominated the annual top 10 list of important technology issues for hospital executives, from the perspective of nonprofit technology research firm ECRI Institute.
Imaging shows toll of vascular brain injury February 14, 2013 -- MR and PET images show that vascular brain injury from conditions such as high blood pressure and stroke has a considerably greater influence on cognitive impairment among nondemented older people than beta-amyloid plaque deposits, according to a study published online February 11 in JAMA Neurology.
Moments in Radiology History: Part 12 -- Radioisotopes February 13, 2013 -- In the latest Moments in Radiology History column, historian Otha Linton traces the path of radioisotopes from physicist Antoine Henri Becquerel and the Curies to cyclotrons in California, the first treatments of cancer patients, and World War II and the atomic bomb.
SNMMI builds global ties with China partnership February 12, 2013 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the Chinese Society of Nuclear Medicine may be worlds apart on a map, but when it comes to priorities and advancing the specialty, the two organizations have much in common.
Study shows PiB-PET detects amyloid plaque in heart February 5, 2013 -- Swedish researchers are expanding the use of PET imaging with carbon-11-labeled Pittsburgh Compound B (PiB) to cardiac amyloidosis, confirming the biomarker's ability to detect amyloid plaque deposits in the heart in a first-of-its-kind study in the February issue of the Journal of Nuclear Medicine.
CMS committee not yet swayed on brain amyloid PET imaging January 31, 2013 -- A U.S. Centers for Medicare and Medicaid Services (CMS) advisory committee said on Wednesday that more studies are needed to confirm the efficacy of Eli Lilly and Avid Radiopharmaceuticals' Amyvid radiopharmaceutical for brain beta-amyloid PET imaging.
PET/CT predicts response to endorectal radiotherapy January 30, 2013 -- PET/CT results can predict which patients will respond to high-dose-rate endorectal brachytherapy for stage II and III rectal cancer, according to a study presented at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium. The results could pave the way for easier treatments and better outcomes.
PET MPI with flurpiridaz F-18 tops SPECT MPI January 30, 2013 -- PET myocardial perfusion imaging (MPI) with flurpiridaz F-18 is "safe and superior" to SPECT MPI with technetium-99m for image quality, interpretation, coronary artery disease diagnosis, and patient tolerance of the tracer, according to a study published in the January 29 issue of the Journal of the American College of Cardiology.
