Other tests

If you are diagnosed with prostate cancer, your treatment team may recommend other tests. These may include a bone scan, CT (computerised tomography) scan, MRI (magnetic resonance imaging) scan or PSMA (prostate-specific membrane antigen) PET-scan.


Bone scan

A bone scan is used to see if any cancer has spread to your bones.
A small dose of radioactive liquid is injected into a vein. You will need to wait for up to four hours for the liquid to travel around your body and collect in your bones. The liquid tends to collect in areas where bone is breaking down and repairing itself. It is these areas (called hot spots) that can be seen on the scan.


CT scan

A CT scan previously known as a CAT scan – is a series of X-rays from different angles that provides more detailed information than a normal X-ray.



MRI scan

This is a scan that uses radio waves and magnetic fields to produce images of the inside of a body.



This new technology is a scan that is available privately in some New Zealand centres. It uses a radioactive solution that attaches to prostate cancer cells so they can be seen in a scan. It is used to identify the spread of prostate cancer beyond the prostate
