New PET tracer could aid melanoma detection
January 17, 2019 -- A new PET tracer designed to target melanin pigment could improve the detection of both primary and metastatic melanoma, according to a study published in the January issue of the Journal of Nuclear Medicine.  Discuss
Both sides weigh in on plan to loosen radiopharma rules
January 16, 2019 -- The U.S. Nuclear Regulatory Commission's proposal to create a way for physicians with little or no background in nuclear medicine to become "limited authorized users" and dispense radiopharmaceuticals is drawing both opposition and support from across the healthcare spectrum.  Discuss
Alzheimer's biomarkers could affect races differently
January 10, 2019 -- Using MRI and PET scans and cerebrospinal fluid assays, researchers have collected data on a variety of key biomarkers that might explain whether Alzheimer's disease develops differently in Caucasians and African-Americans. So far, the preliminary findings are creating more questions than answers in a study published online January 7 in JAMA Neurology.  Discuss
Editorial slams NRC plan to expand radiopharmaceutical users
January 7, 2019 -- An editorial published in the January issue of the Journal of Nuclear Medicine expressed strong objections to actions by the U.S. Nuclear Regulatory Commission (NRC) to promote its alternative pathway for physicians to gain certification to administer radionuclide therapies.  Discuss
United Imaging breaks into U.S. imaging market
January 2, 2019 -- Shanghai-based United Imaging Healthcare (UIH) has officially put down stakes in the U.S. UIH Solutions made its debut at RSNA 2018 with a multimodality line of scanners, including a unique total-body PET scanner.  Discuss
Is menopause a good time to treat women for Alzheimer's?
December 21, 2018 -- By using women's menopausal status and levels of beta-amyloid plaque as markers for possible progression to Alzheimer's disease, researchers are hoping to determine the best time to begin treatment to slow the onset of the condition, according to a study published online December 12 in PLOS One.  Discuss
AI could bring ultralow-dose imaging to amyloid PET
December 18, 2018 -- With the help of artificial intelligence (AI), researchers have developed a way to generate diagnostic-quality images from PET/MR scans to detect amyloid deposits with considerably less radiotracer dose. Their findings were published online December 11 in Radiology.  Discuss
PET tracers help guide breast cancer therapies
December 7, 2018 -- PET imaging tracers that track breast cancer enzymes could help guide treatment of the disease, especially in women with BRCA mutations and triple-negative subtypes of cancer, according to two studies presented this week at the 2018 San Antonio Breast Cancer Symposium.  Discuss
New PET tracer could better connect tau to Alzheimer's
December 7, 2018 -- Clinicians may soon have a new PET tracer to improve the detection of tau protein tangles in the brain, advancing the diagnosis of Alzheimer's disease and subsequently leading to more effective treatments for dementia, according to a study published in the December issue of the Journal of Nuclear Medicine.  Discuss
TOF PET/MRI makes dose reduction viable for breast cancer
December 7, 2018 -- Can clinicians use as little as 10% of the conventional FDG dose and still produce diagnostic-quality images to detect breast cancer? Absolutely. It's feasible using a time-of-flight (TOF) imaging technique with PET/MRI, according to a study published in the December issue of the Journal of Nuclear Medicine.  Discuss
