Perma-Fix advances Tc-99m production technology
October 2, 2015 -- Concern over the future supply of medical isotopes in the wake of recent worldwide shortages and aging nuclear reactors has spawned a kind of cottage industry among entrepreneurs. One such firm is Perma-Fix Medical, which is developing a method for producing technetium-99m (Tc-99m) that does not require uranium.
PET/MRI can be a boon for pediatric cancer patients
September 9, 2015 -- Young pediatric patients may benefit from FDG-PET/MRI for staging and clinically evaluating oncologic disorders, given the hybrid modality's superior soft-tissue contrast and significantly lower radiation dose, according to a study published online August 24 in Investigative Radiology.
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 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
