You are asked to lie on a flat table in a still position without any movements. If you are not able to remain stable during the procedure, the technologist may use straps. In some cases, the doctor recommends an MRI knee with contrast, and for that contrast media is administrated to get a clear image. After that technologist slides the table inside the MRI scanner for the scanning procedure and coils may be placed around your knees to get clear and detailed images. During the scanning, you may experience loud sounds while the scanning is done to obtain the images and the technologist may provide you the headphone to avoid the sound. During the procedure, if you experience any problem, you can communicate with a technologist who is in another room through the intercom. Once the scanning is done, the technologist slides you out of the scanning machine and you can resume your activities.
What are the risks of a Knee MRI scan?

MRI doesn’t use any harmful radiation but still, it is not considered a safe procedure for developing a fetus. Because MRI uses a magnetic field and it may create a problem with metallic implants. If contrast dye is involved in the procedure, some people may experience an allergic reaction.
How much time does Knee MRI scan?
The procedure of a Knee MRI scan may take 15 to 30 minutes and may also take longer if contrast dye is involved.
