Clothing: it is best to wear something light weight and comfortable that is easy to take on and off if needed. Avoid wearing items of clothing that has metal buttons, zippers or hooks.
You will wear a hospital gown or clothes without metal zippers or snaps (such as sweatpants and a t-shirt). Please remove your watches, glasses, jewelry, and wallet. Certain types of metal can cause blurry images. You will lie on a narrow table that slides into a large tunnel-like scanner.
You will be asked to wear a gown for your exam.
You will be asked to remove any clothing containing metal and all jewelry. You will be provided metal free clothing to change into such as gown, shorts or pants. Lockers are available to safely store all personal items such as wallet, purse, keys, phone and other electronic devices.
If you don't need to wear a gown, you should wear clothes without metal zips, fasteners, buttons, underwire (bras), belts or buckles.
The test usually takes 30 to 60 minutes but can take as long as 2 hours.

For a knee MRI, you'll go in feet first, and only your lower body will be in the tube. Expect to hold still for around 15 to 45 minutes, sometimes longer, while the machine makes images of your knee.
Now, hospitals and radiology centers across the country are warning patients who undergo magnetic resonance imaging (MRI) procedures to avoid wearing athletic and spandex clothing. Spandex leggings and other similar athletic wear often contain metallic threads that may react with the machine and cause burn injuries.
For women, if possible, do not wear an underwire bra (the metal can throw off the magnetic field). Sports bras are usually good and we have hospital gowns to change into if necessary. The clasps on the back of a regular bra are not a problem, but avoid wearing bras that have metal parts on the straps.
Be sure to wear clothing that does not have any metal in it (zippers, buttons, etc.). If your clothes do have metal in them, you'll be given a hospital gown to change into for your scan. Normally you can wear your underwear and socks during the scan, unless your radiologist is concerned about metal microfibers.
MRI scans are very useful for diagnosing arthritis. They can provide detailed images of the joint and surrounding tissues. These images help doctors to make a diagnosis and assess the severity of the condition. Getting an MRI scan for arthritis is generally a safe procedure.
In combination with conventional x-rays, MRI is usually the best choice for examining the body's major joints like the knee. The examination is typically performed to diagnose or evaluate: knee pain, weakness, swelling or bleeding in the tissues in and around the joint. damaged cartilage, meniscus, ligaments or tendons.
MRI gives a good picture of the size of a meniscus tear and where it is. It also shows ligaments, cartilage, and tendons. MRIs of the knee are helpful to identify a meniscus tear and to find any related injuries to the ligament, cartilage, and tendons.
You may eat and drink before the exam and take your medications. The day before your exam drink plenty of water so you are well hydrated. Being hydrated will ease the discomfort for those receiving contrast. Patients who are claustrophobic may require oral sedation prior to the MRI scan.
Various clothing items such as athletic wear (e.g., yoga pants, shirts, etc.), socks, braces, and others may contain metallic threads or metal-based anti-bacterial compounds that may pose a hazard. These items can heat up and burn the patient during an MRI.
Please wear comfortable clothing. Cotton, polyester, and wool are best. Don't worry about the snaps or zippers on pants, as that metal can be allowed into the scanning facility. If you have questions about these procedures, please feel free to contact the study coordinator.
fabric and clothes doesn't affect the quality of images.
Position the patient so the knee of interest is as close to the center of the table, left to right, as possible. Rotation of the knee is allowed up to 20 degrees to make the patient comfortable.
What Can You Expect? Full body MRIs can cause some patients to experience feelings of claustrophobia. During a knee MRI, only part of the body enters the scanner tube, yet patients can experience symptoms of claustrophobia. Please make your doctor aware of your claustrophobia prior to scheduling your MRI.
MRI was found to have high sensitivity (90.7%) and moderate specificity (63.6%) in the diagnosis of injuries to the ACL; high sensitivity (90.4%) and moderate specificity (50%) in the diagnosis of injuries to the PCL; moderate sensitivity (79.1%) and low specificity (46.7%) in the diagnosis of injuries to the MCL; fair ...
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
You shouldn't go into an MRI scanning room wearing jewelry or clothing with metal parts.
The radiologist may discuss early results of the MRI with you right after the test. Complete results are usually ready for your doctor in 1 to 2 days. Normal: The ligaments, meniscus, tendons, bones, and joints look normal in size, shape, and location.
