FDA, NRC clear path for U.S. supply of molybdenum-99
February 8, 2018 -- A U.S.-based supply of molybdenum-99 is finally at hand: The U.S. Food and Drug Administration (FDA) has approved NorthStar Medical Radioisotopes' RadioGenix isotope separation system, and the U.S. Nuclear Regulatory Commission (NRC) will license the system's production of technetium-99m for medical use.
Study tracks radiation dose to NM technologists
February 8, 2018 -- A new study published February 1 in Radiology on occupational radiation exposure for nuclear medicine (NM) technologists is serving up some intriguing findings. While radiation exposure is generally low and within established guidelines, it has been rising in recent years as the field adopts more powerful imaging technologies.  Discuss
Flortaucipir-PET could lead in early Alzheimer's detection
February 6, 2018 -- PET scans with the novel radiotracer flortaucipir may provide more valuable information in the early detection of neurodegeneration associated with Alzheimer's disease than MRI, according to a study published in the February issue of the Journal of Nuclear Medicine.  Discuss
PSMA-PET/CT helps spot early prostate cancer recurrence
February 2, 2018 -- PET/CT imaging with gallium-68 prostate-specific membrane antigen (PSMA-11) could help in the early detection and treatment of recurrent prostate cancer after a patient undergoes radical prostatectomy, according to a study in the February issue of the Journal of Nuclear Medicine.  Discuss
Nuclear medicine techs have higher risk of cataracts
January 26, 2018 -- Technologists who perform nuclear medicine exams, either diagnostic or therapeutic, have an increased risk of developing cataracts, according to a study published in the February issue of Radiology.  Discuss
FDG-PET/CT predicts outcomes in pediatric osteosarcoma
January 19, 2018 -- The best way to predict a good outcome for pediatric patients with osteosarcoma is by performing FDG-PET/CT scans at regular intervals in the first several months after the start of chemotherapy, according to a study published in the January issue of the Journal of Nuclear Medicine.  Discuss
New PET radiotracer offers insight into multiple sclerosis
January 12, 2018 -- Combining PET scans with a novel radiotracer could help researchers track damage to myelin in the brain, providing insight into the treatment of multiple sclerosis as well as the development of other disorders, according to a preclinical study published online January 12 in Scientific Reports.  Discuss
Artificial intelligence guides lower PET tracer dose
January 11, 2018 -- In PET imaging, the amount of radiotracer dose correlates with the level of image quality. But what if artificial intelligence (AI) could enable PET to be performed using only 1% of current dose levels -- speeding exam times, decreasing radiation exposure, lowering costs, and alleviating shortages in radiotracers?  Discuss
UC Davis group reports progress on total-body PET/CT
January 5, 2018 -- Researchers at the University of California, Davis (UC Davis) report continued progress on their development of a total-body PET/CT scanner designed to image patients in less than one minute, in an article in the January issue of the Journal of Nuclear Medicine.  Discuss
Deep learning analyzes PET for signs of dementia
December 22, 2017 -- A deep-learning algorithm that analyzed FDG-PET was able to differentiate between normal cognition and dementia. Such models could someday help radiologists diagnose Alzheimer's disease, especially if they don't see the condition often, according to a study presented at the RSNA 2017 meeting.  Discuss
Special Feature
Rad-Aid and the search for meaning in retirement

What do airships, 747s, William Shatner, radiology, and giving back have in common? Semiretired radiologist Dr. Sam Friedman explains how these things are all connected -- and how he found meaning as he transitions away from the daily grind as a radiologist. Read more
