Germ cell tumor other imaging findings

Positron emission tomography (PET) scan
When doing this test, a small amount of a radioactive medium is injected into your body and absorbed by the organs or tissues. This radioactive substance gives off energy which in turn is used to produce the images. PET can provide more helpful information than either CT or MRI scans. It is useful to see if the cancer has spread to the lymph nodes and to locate where the cancer has metastasized.
