Imaging for metastases

bladder. A full bladder helps to keep the bowel away

so the prostate can be better seen. During the scan,

you will need to lie face up on a table. The table will

move through the imaging machine. As the machine

takes pictures, you may hear buzzing, clicking, or

whirring sounds.

Newer tests

There are newer tests for imaging bones and lymph

nodes. Newer tests for bones include PET (






omography) using 18F-NaF for the

radiotracer and hybrid imaging bone scans. There are

also other PET tracers to assess for cancer in lymph


These newer tests appear to detect cancer better

than classic methods. However, more research is

needed to learn what the next steps of care should

be based on the test results. Also, it is unknown how

often these tests should be ordered. To date, there

are no data that show you will have better results with

these newer imaging methods.

Fine-needle aspiration

If the CT or MRI scan suggests that the cancer

has spread into your lymph nodes, a fine-needle

aspiration can confirm if cancer is present. A fine-

needle aspiration is a type of biopsy. It uses a very

thin needle to remove very small pieces of tissue.

A CT scan, MRI, or ultrasound machine is used to

guide the needle into the lymph node. With a local

anesthetic, this test causes little discomfort and

doesn’t leave a scar.
