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
SNMMI: Cerebrovascular risk tied to Alzheimer's disease
June 27, 2018 -- PHILADELPHIA - A study on amyloid plaque accumulation, white-matter hyperintensity, and cortical thickness has found that a patient's cerebrovascular characteristics should be considered for their potential effect on the progression of Alzheimer's disease. The findings were presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.  Discuss
SNMMI: AI enables stress-first SPECT MPI protocol
June 27, 2018 -- PHILADELPHIA - Artificial intelligence (AI) analysis of stress SPECT myocardial perfusion imaging (MPI) can be highly sensitive for all types of coronary artery disease, according to research presented Tuesday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.  Discuss
