For the health of it.
Prostate Imaging centers on three major health problems centered on the prostate gland: cancer, benign enlargement and inflammation (the cause of most urinary tract infections). Radiology plays an important role in diagnosing and treating these problems.
What are my options?
Prostate MRI is considered by many medical experts to be the most advanced method available to screen and stage prostate cancer. Although a Prostate MRI imaging study is not appropriate for all men, if you or a loved one are concerned about the risk of developing prostate cancer we encourage you to talk to your doctor about MRI prostate cancer screening and staging.
A man’s prostate gland and surrounding tissue are examined via insertion of an ultrasound probe into the patient’s rectum. There are no harmful effects, and it gives a clearer picture of soft tissues than X-ray images.
In one method, several fiducial markers, or tiny pieces of biologically inert metal such as gold, are placed in the prostate gland before the simulation. Digital X-ray images are taken which localize the metallic markers to check the position of the prostate on a daily basis just before the treatment, and the prostate is appropriately adjusted and aligned to the planned high-dose radiation treatment field.
Another method involves using ultrasound to localize the prostate before each treatment. The patient is asked to keep his bladder full as much as possible in order to produce a good ultrasound image, and also to displace the bladder mucosa out of the radiation treatment field.
A third method involves the use of a low-dose computed tomography (CT) scan of the prostate area in the treatment couch right before each treatment to verify prostate position. Depending on your case and available technology at your treatment center, your physician will inform you of the type of image-guided radiation therapy you will receive.
