PET imaging using the radiotracer ⁶⁸GA-PMSA shows good promise for aiding early detection of lymph-node metastases in patients with recurrent prostate cancer, as researchers in Germany and the U.K. have shown the modality more accurate than morphological imaging—and likely capable of guiding salvage lymphadenectomy.  {read more here}

A recent pilot study found that sodium fluoride (Na-F-18) positron emission tomography/computed tomography (NaF-PET/CT) accurately detects bone metastases in patients with advanced prostate cancer, and follow-up scans over time correlate clearly with clinical outcomes and patient survival. {read more here}

Health care is unique in its economics, but regardless of how it’s defined, an emerging market is clear: consumerism and information seeking, Saurabh Jha, MBBS, assistant professor of radiology at the Hospital of the University of Pennsylvania, said at ACR 2016. {read more here}

A new study reveals how dopamine contributes to working memory. Using simultaneous positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), scientists have shown that the density of cortical dopamine D1 receptors in healthy individuals is related to a decoupling of the frontoparietal and default networks. {read more here}
