MRI Knee With & Without Contrast

A knee MRI scan is an imaging exam that explicitly examines the knee and its surrounding areas. The images show the soft tissues and bones of the knee joint, a hinge synovial joint that connects the femur (upper leg), tibia (lower leg), and patella (kneecap). The knee joint also contains some soft tissues and muscle, which allow extension, flexion, medial and lateral rotations. MRI scans utilize radio waves and magnets to capture photographs of the soft tissue (like organs and muscles) and bones inside your body to allow doctors to diagnose complications in your knee and knee joint.
Your doctor might order an MRI scan of your knee to scan for abnormalities in your knee joint. The MRI will allow doctors to observe the anatomy of your knee to determine the possible reasons for your pain, inflammation, or knee complications without surgery. A knee MRI is usually ordered to help doctors diagnose and treat many types of conditions such as bone fractures, infection, arthritis, and other degenerative joint disorders, damage to your cartilage, tendons, and ligaments, the reduced motion of the knee joint, fluid buildup in the knee, problems with implanted medical devices, sports injury, and tumors. Your doctor may order an MRI arthrogram, a particular sort of MRI scan, where a contrast fluid or dye is injected into your knee. This is done to provide a better view of its structure for this procedure.
An MRI is usually used after an X-ray has been unable to diagnose knee problems. Your doctor may order a knee MRI scan if they suspect the following:
  • Soft-tissue changes
  • Bone density: MRIs aren't enough for evaluating bone quality. A bone density test is required for that, but it can detect abnormalities (e.g., certain bone disorders, bone thinning, osteoporosis).
  • Alignment issues
  • Joint spaces
  • Early arthritis signs
  • Injury/fracture: MRIs show evidence of trauma to the bone, including fractures.
There is no need to prepare for this exam. However, you have to change into a hospital gown and remove jewelry and piercings before the scan. Tell your doctor if you have artificial heart valves, implants, plates, prosthetic joints or limbs, or stents in your body since an MRI machine uses magnets. Also, let them know if you are allergic to any dyes. Also, tell your doctor if you have a pacemaker so another imaging exam can be used to inspect your knee, such as a CT scan. However, some models are reprogrammable, so they're not a hindrance to the scan. If you're claustrophobic, being in the MRI machine can be triggering. In this case, you can get anti-anxiety medications or even be sedated for the exam.
For this MRI, a gadolinium-based contrast agent (GBCAs) is used, a type of MRI dye, to add clarity and decipherability to your MRI image. A nurse will inject the dye intravenously into your arm before the scan. Then the MRI technician will have you lie on your back on a padded table in the MRI machine. The technician may use pillows or support to make your knee more comfortable during the test and help keep your leg still so the machine can take the most precise MRI images. The technician will then control the bench's movement from another room and slide the table into the MRI machine. They will also communicate with you through a speaker in the MRI machine. The process usually takes half an hour to an hour. The machine will make some loud and repetitive humming noises as the MRI image is obtained. You have access to a call button in case you become uneasy during the test. If you are sedated, your heartbeat, breathing, and oxygen levels will all be monitored during the exam for your safety. The MRI technician may ask you to hold your breath for a few seconds during the exam.
The MRI technologist will give your MRI images to a radiologist trained to interpret scans and write a report on them. Your doctor will then receive the report and discuss it with you and explain the findings. Usually, this will take one or two days; however, if the MRI was done on an emergency basis, the MRI facility could provide the results quickly.
