ABSTRACT
ABSTRACT: 18 F-DCFPyl is a Food and Drug Administration-approved radiotracer that targets prostate-specific membrane antigen and is used in the detection of recurrent or metastatic prostate cancer. As its use has increased, a growing number of nonprostatic disease entities have been identified that express prostate-specific membrane antigen and can mimic prostate cancer. Thus, the interpreting physician must also consider other variables such as serum prostate-specific antigen levels and the distribution of uptake to avoid an inappropriate diagnosis of metastatic prostate cancer. We describe 18 F-DCFPyl uptake associated with a hepatic small vessel neoplasm, an association previously undescribed in the literature.

Tissue engineering and regenerative medicine have adopted the use of extracellular matrix (ECM) as a cell delivery device and bioactive regenerative agent. To this end, many ECMs have been investigated for cardiac tissue engineering and regenerative medicine applications with variable success. Many sources of natural ECMs have been tested for cardiac applications. Typically, natural ECMs have been made from decellularized organs or tissues and processed into either sheets or injectable hydrogels. This chapter will review natural sources of ECM materials that have been tested as therapeutic agents in models of heart failure.
