A pelvic MRI is performed by having you lie on a table that slides into a large, cylindrical MRI machine. Here's a more detailed breakdown:
Preparation:
- You'll typically be asked to change into a gown and remove any metal objects like jewelry, watches, or belts, as these can interfere with the MRI's magnetic field.
- Inform the technician of any implants or medical devices you have (e.g., pacemakers, metal implants, IUDs). Certain implants may be unsafe for MRI.
- In some cases, you may receive an injection of a contrast dye (gadolinium) intravenously to enhance the images. If you have kidney problems or allergies, you must inform your doctor beforehand.
Procedure:
- Positioning: You'll lie on your back on a narrow, padded table.
- Coil Placement: Small devices called coils will be placed around your pelvic area. These coils help improve the image quality by sending and receiving radio waves. Different types of coils are used depending on what area of the pelvis needs to be visualized.
- Table Movement: The table will slide into the large, tunnel-like opening of the MRI machine.
- During the Scan: The MRI machine will make loud knocking or buzzing noises. You will be provided with earplugs or headphones to reduce the noise. It's important to remain as still as possible during the scan to avoid blurring the images. You can usually communicate with the technician through an intercom.
- Breathing Instructions: You may be asked to hold your breath for short periods during certain sequences. This helps minimize movement artifacts and improve image clarity.
- Scan Duration: The entire procedure usually takes between 30 to 60 minutes, depending on the specific areas being examined and whether contrast is used.
Post-Procedure:
- You can usually resume your normal activities immediately after the MRI, unless you received sedation.
- If you received contrast, it’s important to drink plenty of fluids to help your kidneys flush it out of your system.
In summary, a pelvic MRI involves lying still inside an MRI machine while radio waves and a magnetic field create detailed images of your pelvic organs and structures.
