Throughout the exam, the equipment will produce a lot of noise, but you will always be able to speak with the technician over the intercom. Usually, the entire procedure takes thirty minutes or less. An MRI of the knee has no hazards, and there is no need to prepare for it beforehand.
How to Work Knee MRI
A magnetic resonance imaging (MRI) of the knee is a medical imaging method that shows the structures inside and surrounding the knee joint. It offers fine-grained pictures of ligaments, tendons, cartilage, and other soft tissues. This is a brief overview of what to anticipate and the usual procedure for a knee MRI:
Before the MRI:
- Preparation:
- Before the MRI, you may be asked to change into a hospital gown and remove any metal objects, including jewelry and accessories.
- Inform the technologist if you have any metal implants or devices in your body, such as pacemakers or metal joint replacements.
- Screening:
- You will undergo a screening process to ensure it’s safe for you to enter the magnetic field of the MRI machine.
- Patient Positioning:
- You will lie down on a moveable examination table, and the knee to be examined will be positioned in the center of the MRI machine.
During the MRI:
- Communication:
- You’ll be provided with earplugs or headphones to protect your ears from the loud noises produced by the MRI machine. Communication with the technologist is usually maintained through an intercom system.
- Immobilization:
- To obtain clear images, it’s important to remain as still as possible during the scan. Straps or foam pads may be used to help immobilize the knee.
- Contrast Agent (if used):
- In some cases, a contrast agent (dye) may be injected into a vein to enhance the visibility of certain structures. This is more common in cases where detailed visualization of blood vessels or soft tissues is required.
- Series of Scans:
- The MRI machine will produce a series of images, each lasting a few minutes. You may hear loud knocking or tapping sounds during the scan, which is normal.
After the MRI:
- Resume Normal Activities:
- In most cases, you can resume normal activities immediately after the MRI unless you were given a sedative.
- Results:
- The MRI images will be interpreted by a radiologist, and the results will be shared with your referring healthcare provider. They will discuss the findings and any necessary next steps with you.
Tips for a Successful Knee MRI:
- Follow any specific instructions provided by the healthcare team.
- Inform the technologist about any claustrophobia or anxiety you may have.
- Stay as still as possible during the scan to ensure clear images.
- If you have concerns or questions, don’t hesitate to communicate with the healthcare team.
