Ga-68 PSMA-11 PET/MRI advances prostate cancer detection
September 25, 2018 -- PET/MRI scans with a gallium-68 (Ga-68)-labeled radiopharmaceutical that homes in on prostate-specific membrane antigen (PSMA)-11 could become a mainstay in prostate cancer detection, given its ability to significantly outperform multiparametric MRI alone, according to a study published online September 18 in Radiology.  Discuss
Flortaucipir-PET targets tau for Alzheimer's diagnoses
September 21, 2018 -- By binding to the tau protein associated with Alzheimer's, PET imaging with the tracer flortaucipir can distinguish between the disease and other neurodegenerative conditions with similar symptoms, according to an international study published in the September 18 issue of the Journal of the American Medical Association.  Discuss
Delayed NaF-PET enhances coronary plaque detection
September 18, 2018 -- In life, timing is everything. With sodium fluoride (NaF) PET, interpreting results three hours after tracer injection instead of the customary one-hour delay improved image quality and standardized uptake values, leading to significantly better coronary plaque detection, according to a September  13 article in the Journal of Nuclear Medicine.  Discuss
PET/CT makes case for directing cervical cancer treatment
September 14, 2018 -- Can FDG-PET/CT be used to direct the treatment of locally advanced cervical cancer by determining which patients should receive more extensive chemoradiation therapy or palliative care? Maybe, but findings from a new study published online September 14 in JAMA Network Open are equivocal.  Discuss
Imaging modalities differ in assessing key heart metric
September 6, 2018 -- There is "substantial variability" in the way that different medical imaging modalities measure left ventricular ejection fraction, a key measure of heart function. This variation should be seriously considered before patient treatment, according to an international study published online August 31 in JAMA Network Open.  Discuss
SPECT shows causes of accelerated brain aging
August 22, 2018 -- Abusing marijuana can add years to your brain's age. And so can bipolar disorder, schizophrenia, and a number of other factors, according to a study published online August 3 in the Journal of Alzheimer's Disease. Researchers using SPECT found evidence of accelerated brain aging among people with various disorders and behaviors.  Discuss
SNMMI letter urges FDA to ease shortage of gallium-68
August 15, 2018 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) has written a letter to the U.S. Food and Drug Administration (FDA) urging it to take steps to ease the shortage of the radioisotope gallium-68 for use in PET to diagnose neuroendocrine tumors.  Discuss
Nuclear medicine duties not always shared equally
August 14, 2018 -- What's in a name? Apparently a lot when it comes to nuclear medicine. Physicians who identify themselves as nuclear medicine specialists devote at least 90% of their time to nuclear medicine duties, while most who call themselves nuclear radiologists or nuclear cardiologists devote 10% or less, according to a study published online August 7 in the American Journal of Roentgenology.  Discuss
Prescan tutorial eases patient concerns about PET/CT
August 13, 2018 -- Giving patients knowledge of what to expect from an upcoming FDG-PET/CT scan can go a long way toward helping them to relax and improving their experience, according to a study published online August 3 in the Journal of Nuclear Medicine Technology.  Discuss
