Imaging Tests of the Urinary Tract
Positron emission tomography
Newly available nuclear positron emission tomographic (PET) contrast agents can detect prostate cancer that has spread (metastasized) to other areas of the body. This nuclear contrast agent targets PMSA (prostate-specific membrane antigen) on the surface of prostate cancer cells, which then show up on a PET scan. In contrast, routine PET scans are not very useful for most cases of prostate cancer but can be useful for other genitourinary tumors such as those of the Kidney Cancer or
