What to Expect During a Prostate MRI Scan
If you’ve never had a prostate MRI scan before, it can sound a bit intimidating. Traditionally, the exam used to screen for prostate cancer was a Digital Rectal Exam (DRE), during which a clinician would insert a lubricated, gloved finger into the rectum to feel the back of the prostate for any lumps or irregularities. Today, DRE is typically seen as outdated and inferior to modern imaging tools, such as prostate MRI, and the two exams have very little in common in terms of patient experience. Still, knowing what to expect during a prostate MRI can help demystify the process and give you the confidence you might need to ask important questions and advocate for your health during screening.
What Is a Prostate MRI Scan?
A prostate MRI is an imaging test which, like all MRIs, uses a powerful magnetic field and radio waves to create detailed images of internal anatomy, in this case, the prostate gland and surrounding tissue. Unlike X-ray and CT scans, MRI does not use any ionizing radiation. The primary goal of prostate MRI is to create images that doctors can then examine for irregularities or suspicious areas that could indicate prostate cancer, or to assess the extent of existing prostate cancer and monitor changes over time.
The exam is completely non-invasive, and a fleet enema is typically advised prior to the exam. Any additional instructions will be explained by our staff when you call to schedule.
What Happens During a Prostate MRI Scan?
Because MRI relies on what is essentially just a very powerful magnet, when you arrive for your appointment you’ll be asked to remove any metal objects on your person, such as watches, jewelry, and any clothing with metal fasteners. Some imaging centers will have you change into a hospital gown before the exam, while others may offer it but not require it.
You’ll then be asked to lie on a padded table that slides into the MRI scanner. It is very important that you remain as still as possible during the exam so the images captured are clear. During the scan, the machine will make a series of loud tapping and knocking noises, and you’ll typically be given earplugs or headphones before entering the scanner to help with the noise.
Many prostate MRIs will also involve the use of a contrast agent delivered intravenously. The purpose of this is simply to highlight blood flow and make it easier to see certain potential abnormalities. If a contrast agent is used, it will be delivered by a small IV in your arm during the scan. Historically, prostate MRIs often involved the use of an endorectal coil, which is a medical device with a small balloon on the end that would be placed inside the rectum; however, this is no longer common with modern, high-strength MRIs.
The scan itself will likely take between 30 and 45 minutes, though the length can vary depending on the specific type of imaging being performed. Throughout the exam, you’ll be able to speak with the technician through an intercom if you have any questions or concerns. Once imaging is complete, you’ll be able to return to normal activities unless advised otherwise by your healthcare provider.
