Quantitative PET better estimates amyloid plaque burden
October 18, 2018 -- Dutch researchers have developed a quantitative method of analyzing PET images acquired with the radiopharmaceutical flutemetamol that may top semiquantitative methods for identifying dementia-causing amyloid plaque, according to a study published online October 12 in the Journal of Nuclear Medicine.  Discuss
Can dedicated breast PET identify suspicious lesions?
October 9, 2018 -- A dedicated breast PET scanner fell short in a European research study assessing its value for detecting cancer in women with suspicious mammograms. Spanish researchers found the system missed nine of 18 cancers in a small group of 50 women, according to an October 3 study in the European Journal of Radiology.  Discuss
FDG-PET/CT fails for peripheral T-cell lymphoma outcomes
October 5, 2018 -- Don't expect much help from FDG-PET/CT results in predicting progression-free or overall survival among patients with peripheral T-cell lymphoma, according to a study published in the October issue of Clinical Lymphoma, Myeloma and Leukemia.  Discuss
PET/CT predicts success of rad therapy for spinal mets
October 3, 2018 -- FDG-PET/CT scans can predict the success of radiation therapy in patients with spinal metastases, especially in regard to progression-free survival, according to a study published online September 28 in PLOS One.  Discuss
PET/MRI motion correction gives readers more confidence
October 2, 2018 -- A motion correction algorithm applied to PET/MRI scans resulted in more accurate scans with fewer false positives, and readers were more confident in their interpretations, according to study results published in the September issue of the Journal of Nuclear Medicine.  Discuss
FDG-PET/CT helps stage men with breast cancer, too
September 26, 2018 -- Assessing breast cancer in men is an uncommon clinical use for FDG-PET/CT, but the hybrid modality achieves results comparable to those in women in regard to accurate staging of the disease, according to a study published online September 21 in the Journal of Nuclear Medicine.  Discuss
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
