How It Is Done
A testicular scan is usually done by a nuclear medicine
technologist. The scan pictures are usually interpreted by a
radiologist or
nuclear medicine specialist.
You will need to remove any jewelry that might interfere with the
scan. You may need to take off all or most of your clothes, but you will be
given a cloth or paper covering to use during the test.
The technologist cleans the site on your arm where the radioactive
tracer will be injected. A small amount of the radioactive tracer is then
injected.
You will lie on your back on a table and your penis will be taped
to your abdomen to prevent it from interfering with the scan. A sling or towel
may be used to support the testicles under the scanner. After the radioactive
tracer is injected, the camera will scan for radiation released by the tracer
and produce pictures of the tracer in your testicles. Two scans are done about
15 minutes apart. You need to lie very still during each scan to avoid blurring
the pictures. The camera does not produce any radiation, so you are not exposed
to any additional radiation while the scan is being done.
A testicular scan takes about 45 minutes.
