PET with tau agent sheds light on Alzheimer's disease
July 25, 2016 -- PET imaging of tau proteins with a novel radiotracer based on fluorine-18 is showing great promise in differentiating between Alzheimer's patients and cognitively normal individuals and identifying how the disease may develop, according to a study published online July 25 in JAMA Neurology.
Does imaging after thyroid cancer treatment help?
July 21, 2016 -- Yes, surveillance imaging can identify the recurrence of thyroid cancer in patients who have received treatment. But that doesn't mean the scans will affect patient survival, according to a large retrospective study published online July 21 in BMJ.
Very low calcium scores do not guarantee negative MPI
July 12, 2016 -- Symptomatic patients with very low coronary artery calcium scores are almost as likely to have a positive SPECT myocardial perfusion imaging (MPI) scan and a subsequent cardiac event as patients with higher calcium scores, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting.
PET/MRI technique shows promise for prostate cancer
July 12, 2016 -- The combination of F-18 choline PET and multiparametric MRI shows promise for detecting prostate cancer, according to a study in the July issue of the Journal of Nuclear Medicine.
FDG-PET/CT aids assessment of lower-stage breast cancer
June 29, 2016 -- FDG-PET/CT's ability to find a significant number of distant metastases in patients with newly diagnosed stage IIB triple-negative breast cancer suggests that current guidelines from the National Comprehensive Cancer Network for the modality's use may need to be revised.
Prostate radiotracer may benefit breast cancer imaging
June 24, 2016 -- A radiotracer recently cleared for PET imaging of recurrent prostate cancer may have similar efficacy for certain forms of breast cancer, according to a study presented at last week's Society of Nuclear Medicine and Molecular Imaging meeting.
Novel PET combination awarded SNMMI Image of the Year
June 15, 2016 -- SAN DIEGO - German researchers have received this year's Image of the Year award from the Society of Nuclear Medicine and Molecular Imaging (SNMMI) for the use of three different radiotracers with PET to measure amyloid plaques, tau tangles, and metabolic activity in the brains of living Alzheimer's patients.
SNMMI: FDG-PET predicts breast cancer outcomes
June 15, 2016 -- SAN DIEGO - FDG-PET is a considerably better predictor of treatment response and outcome than fluoride-PET for breast cancer patients with metastatic bone lesions, concluded researchers on Tuesday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) conference.
SNMMI: PET shows tau may be Alzheimer's catalyst
June 14, 2016 -- SAN DIEGO - In a comparison of PET images with three different radiotracers, German researchers found that tau deposits may be more influential in causing Alzheimer's disease than amyloid accumulation, according to results presented on Monday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting.
SNMMI: PiB-PET finds unique Down syndrome trait
June 13, 2016 -- SAN DIEGO - Using carbon-11-labeled Pittsburgh Compound B (PiB) with PET, researchers have tracked an unusual increase in beta-amyloid plaque in the striatum region of the brain among people with Down syndrome, according to a study presented on Sunday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.
