Who is this test best for?
Men with elevated PSA levels to determine the prostate size or to locate signs of prostate cancer in images of the prostate. These images can aid diagnosis or guide biopsies.

Who orders or performs the test?
What are common side effects?
None, although the procedure may be a little uncomfortable.
