Abstract
Prostate cancer imaging has become an important diagnostic modality for tumor evaluation. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) has been extensively studied, and the results are robust and promising. The advent of the PET/magnetic resonance imaging (MRI) has added morphofunctional information from the standard of reference MRI to highly accurate molecular information from PET. Different PSMA ligands have been used for this purpose including 68gallium and 18fluorine-labeled PET probes, which have particular features including spatial resolution, imaging quality and tracer biodistribution. The use of PSMA PET imaging is well established for evaluating biochemical recurrence, even at low prostate-specific antigen (PSA) levels, but has also shown interesting applications for tumor detection, primary staging, assessment of therapeutic responses and treatment planning. This review will outline the potential role of PSMA PET/MRI for the clinical assessment of PCa.

Abstract
Molecular imaging using 16α-[18F]fluoro-17β-estradiol (FES) and 18F-fluoro-furanyl-norprogesterone PET can assess in vivo function of steroid hormone receptors in breast cancer. These experimental agents have been tested in many single-center clinical trials and show promise to elucidate prognosis and predict endocrine therapy response. The current multicenter trial of FES-PET imaging will help bring this radiotracer closer to clinical use. There is tremendous potential for these tracers to advance drug development, enhance understanding of estrogen receptor-positive tumor biology, and personalize treatment.
