MRI For Prostate Cancer: Indications and Usage
What is MRI?
MRI (magnetic resonance imaging) is an imaging technique that uses a strong magnetic field and radio waves to create detailed images of the inside of the body.
When is MRI used for prostate cancer?
MRI is used to diagnose prostate cancer, stage the cancer, and monitor the response to treatment. MRI can also be used to guide biopsies of the prostate.
Diagnosis of prostate cancer
MRI can be used to diagnose prostate cancer by identifying areas of the prostate that are abnormal. These areas may be cancerous or they may be benign (non-cancerous).
Staging of prostate cancer
MRI can be used to stage prostate cancer by determining the extent of the cancer within the prostate and whether it has spread to other parts of the body.
Monitoring the response to treatment
MRI can be used to monitor the response to treatment for prostate cancer by showing how the cancer is responding to the treatment.
How is MRI performed?
MRI is performed by lying on a table that is moved into a large magnet. The magnet creates a strong magnetic field that aligns the protons in the body. Radio waves are then used to excite the protons, which causes them to release energy. This energy is detected by the MRI scanner and used to create images of the inside of the body.
What are the benefits of MRI?
MRI is a non-invasive imaging technique that does not use radiation. It is also a very accurate imaging technique that can provide detailed images of the inside of the body.
What are the risks of MRI?
MRI is generally a safe procedure. However, there are some risks associated with MRI, including:
- The strong magnetic field can cause interference with metal objects, such as pacemakers and surgical clips.
- The MRI contrast agent can cause allergic reactions in some people.
- MRI can be uncomfortable for some people, especially those who are claustrophobic.
How do I prepare for an MRI?
Before an MRI, you will need to remove all metal objects from your body, including jewelry, watches, and clothing with metal zippers or buttons. You will also need to tell your doctor if you have any metal implants or devices in your body.
