PET/MRI matches PET/CT for recurrent pelvic cancer
September 4, 2015 -- PET/MRI can provide high diagnostic performance for restaging gynecological cancer patients compared with FDG-PET/CT, with only slightly longer scan time and "markedly reduced" radiation exposure, according to a German study published online August 19 in the European Journal of Radiology.
PET/MRI makes clinical inroads, but work remains
August 31, 2015 -- PET/MRI is making progress in moving from being a research technology to a modality that's used clinically. Radiologists who use it frequently are recognizing its value for several applications, but work remains in convincing referring physicians of its worth.
IDEAS study to explore amyloid PET and Alzheimer's
August 20, 2015 -- Over the next five to six years, researchers, clinicians, patients, and a host of nonprofit organizations from across the U.S. will collaborate to tackle a few of the nation's most vexing and complex health issues via the Imaging Dementia -- Evidence for Amyloid Scanning (IDEAS) study of Alzheimer's disease, dementia, and cognitive impairment.
CCTA, SPECT MPI yield similar outcomes in chest pain
August 13, 2015 -- Although they provide different radiation exposure levels and patient experiences, SPECT myocardial perfusion imaging (MPI) and coronary CT angiography (CCTA) produce remarkably similar outcomes in initial imaging for chest pain, according to a new study.
U.S. team finds favor with new PEM unit
August 7, 2015 -- A positron emission mammography (PEM) unit developed in Spain offers key advantages for breast imaging, according to a Mayo Clinic team that has been testing it. The unit offers better resolution than whole-body PET, and it may prove more useful than molecular breast imaging using technetium-99m sestamibi.
PET/CT tumor volume best predicts breast cancer survival
July 30, 2015 -- Whole-body metabolic tumor volume, as determined by FDG-PET/CT before treatment, is a reliable prognosticator of overall survival in patients who have invasive ductal carcinoma of the breast and distant metastases at the time of their initial diagnosis, according to a study published online July 23 in the American Journal of Roentgenology.
Guerbet bids to buy Mallinckrodt's contrast business
July 27, 2015 -- French contrast agent developer Guerbet plans to acquire the contrast media and injector business of U.S. firm Mallinckrodt. The $270 million deal will double Guerbet's annual revenues, expand its product line, and instantly make the company a major player in the U.S. contrast market.
SPECT distinguishes TBI, PTSD in broad population
July 20, 2015 -- SPECT is once again showing its value by distinguishing the fine line between post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) in nonmilitary patients, which should lead to better treatment for the disorders.
Brain SPECT shows improvement after cocaine users abstain
July 10, 2015 -- Dysfunction in the prefrontal cortex region of the brain caused by excessive cocaine use may be reversed to some degree after more than one month of abstinence, researchers from Uruguay have found. Their findings are promising news for rehabilitation efforts, but the group cautioned that some brain dysfunction does appear to remain.
Proposal would dissolve ABNM, fold functions into ABR
June 25, 2015 -- In the face of an increasingly difficult job market for nuclear medicine physicians, a proposal has been floated to dissolve the American Board of Nuclear Medicine (ABNM) and fold its functions into the American Board of Radiology (ABR). The combined organization would oversee a new, broader certification for imaging specialists.
