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
SNMMI: Theranostic agent awarded Image of the Year
June 27, 2018 -- PHILADELPHIA - A PET image that shows the combined power of the diagnostic and therapeutic (theranostic) use of molecular imaging to identify and treat metastatic castration-resistant prostate cancer has been named this year's Image of the Year at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.  Discuss
Special Feature
Men greatly outnumber women in academic nuclear medicine

The under-representation of women in academic diagnostic radiology has had a ripple effect in nuclear medicine, where men outnumber women by almost 6-to-1 in professorial and leadership positions in the U.S. and Canada. Read more
