Abstract:
The continuing adoption of prostate specific membrane antigen (PSMA)-targeted PET for prostate cancer molecular imaging requires imagers and clinicians alike to be aware of the increasing number of potential interpretive pitfalls that have been reported. This review summarizes and illustrates the spectrum of benign and malignant nonprostatic conditions with high PSMA-radiotracer uptake that may be mistaken for sites of prostate cancer and also discusses potential false negatives. We discuss the recent literature on the effect of androgen deprivation therapy on lesion detection. Furthermore, we briefly review the recently proposed structured reporting systems for the standardized interpretation of PSMA-targeted PET that can guide both imaging specialists and referring clinicians in the appropriate interpretation and work-up of pitfalls.

Antigen Presenting Cells
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
