Australian agency orders review of Mo-99 procedures
July 20, 2018 -- An Australian government agency has ordered a review of radiation safety procedures at another federal agency in charge of running the nuclear reactor that was forced to stop shipments of the radioisotope molybdenum-99 (Mo-99) last month. The halt has spurred an ongoing shortage of important radiopharmaceuticals in the country.  Discuss
FDDNP-PET shows brain injury effects in military personnel
July 19, 2018 -- Researchers have found that changes in PET scans of military personnel with mild traumatic brain injury are similar to those seen in retired football players with suspected chronic traumatic encephalopathy, according to a study published online July 17 in the Journal of Alzheimer's Disease.  Discuss
PET could make synaptic density an Alzheimer's biomarker
July 17, 2018 -- Researchers from Yale University are reporting promising results with a PET tracer designed to assess synaptic density in patients with Alzheimer's disease. The hope is that the approach could become an in vivo biomarker for dementia and help in therapy development, according to a paper published online July 16 in JAMA Neurology.  Discuss
Women's menstrual phase may increase radiation risk
July 13, 2018 -- Hormonal changes caused by a woman's menstrual cycle may put them at higher risk of developing cancer from exposure to medical radiation, according to a letter published July 10 in Radiology. Providers may want to consider menstrual phase when deciding when to perform studies -- particularly nuclear medicine exams -- in younger women, the researchers recommended.  Discuss
C-11-based PET tracer could benefit arthritis patients
July 9, 2018 -- Carbon-11 (C-11) PET that targets translocator protein expression in the joint lining tissue of the knee may be a better way to determine the extent of rheumatoid arthritis, according to a study published in the July issue of the Journal of Nuclear Medicine.  Discuss
Time-of-flight PET can reduce radiation dose in pediatrics
July 9, 2018 -- By adding a time-of-flight technique to pediatric PET scans, clinicians can adjust radiation dose levels by as much as 50% with no discernible loss of diagnostic image quality, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting in Philadelphia.  Discuss
Australian reactor woes worry nuclear medicine
July 6, 2018 -- The shutdown of shipments from a nuclear reactor in Australia that is a key part of the global supply network for the radioisotope molybdenum-99 is causing consternation in the nuclear medicine community, particularly in the Asia-Pacific region.  Discuss
Can deep learning monitor lesions on F-18 NaF PET/CT?
July 5, 2018 -- Deep learning can classify bone lesions found on F-18 sodium fluoride (NaF) PET/CT exams, potentially enabling monitoring of individual lesions and faster interpretation times, according to research presented recently at the Society of Nuclear Medicine and Molecular Imaging annual meeting in Philadelphia.  Discuss
Cardiac hybrid imaging predicts adverse cardiac events
July 3, 2018 -- A cardiac hybrid imaging technique that fuses SPECT myocardial perfusion imaging with coronary CT angiography scans can help predict major adverse cardiac events in patients suspected of having coronary artery disease, according to a study published online July 3 in Radiology.  Discuss
Novel nanoSPECT/CT radionuclide could aid cancer therapy
July 3, 2018 -- Swedish and Dutch researchers are reporting early progress in combining nanoSPECT/CT with a novel pretargeted radionuclide therapy for cancer that so far is nontoxic to the kidneys, according to a preclinical study published in the July issue of the Journal of Nuclear Medicine.  Discuss
