Knee MRI Scan in Midtown Manhattan

The knee is a complex joint that comprises bones, ligaments, tendons, and cartilage that work together to support joint function. Knee pain is a common problem usually associated with general wear and tear from daily activities like walking, bending, standing, and lifting. It can also result from some injury, mechanical problems, types of arthritis, and other medical issues.

Knee pain is not only debilitating but also affects your movement and range of motion. If left untreated, it may result in long-term damage and mobility issues. An MRI can help your doctor see what might be causing your symptoms.

What Is a Knee MRI?

Anatomy of the Human KneeMagnetic resonance imaging is a safe and powerful diagnostic procedure that uses magnetic fields, radio waves, and a computer to produce detailed images of structures within the knee.  An MRI of the knee is a non-invasive, effective, and rapid means of identifying many different injuries and conditions affecting this joint.

The technology produces images in multiple planes, which allows physician to see the knee thoroughly from different angles, detect abnormalities, and identify the causes of your knee pain and other unusual symptoms.  An MRI is the most effective way to assess the soft tissue structures in the knee joint, such as the ligaments, muscles, tendons, and cartilage, and diagnose a wide range of problems, from ligament tears to meniscus injuries and other damage.

With a knee MRI, doctors can prepare for knee surgery, monitor post-surgical recovery, and plan appropriate treatment.

When Do You Need a Knee MRI Scan?

An MRI is usually the best choice for examining the body’s major joints, like the knee. It is performed to diagnose or evaluate several injuries and conditions, including:  

Ligament injuries such as ACL and MCL tears that usually occur in athletes

  • Meniscal tears, when the knee is twisted and cause injuries to the cartilage
  • Patellar issues, including dislocation or tracking issues of the knee cap
  • Bone fractures and contusions that lead to bone damage
  • Degenerative diseases such as osteoarthritis
  • A build-up of fluid in the knee joint
  • Infections
  • Tumors involving bones and joints
  • Decreased motion of the knee joint
  • Knee cap injury or pain
  • Complications related to implanted surgical devices
  • Pain or trauma following knee surgery

Your physician may order an MRI of the knee to examine the joint if they suspect a structural abnormality or some other ailment. They will be able to determine if you need an MRI scan based on a physical examination and your medical history.

MRI is usually recommended if you experience any of these symptoms:

  • Pain in your knee that does not improve over time
  • Weakness in your knees and legs
  • Swelling or stiffness in your knee
  • Difficulty bearing weight on your leg
  • Numbness or tingling in your foot or ankle
  • Pain accompanied by fever

The detailed images help your doctor visualize the anatomy of your knee to determine the possible cause of your pain, inflammation, or weakness, without surgery.

How to Prepare for an MRI of the Knee?

Knee MRI MachineAn MRI does not require special preparation, but you should follow the instructions provided by your doctor to ensure the procedure goes smoothly and achieves accurate results.

  • Ask your doctor if you can continue to eat or drink and take medications before the test. Some MRIs require you not to eat at least 4 hours before the scan. Follow your doctor’s instructions.
  • Remove all piercings and jewelry and leave them at home with other valuables, as nothing is allowed in the scanning room. Metal objects can interfere with the scanning process.
  • Avoid putting on makeup, perfume, lotion, or deodorant on the day of the scan, as some of them can contain metallic traces, which disturb the magnetic field.
  • Inform your doctor or technologist about any significant medication history or allergies, especially contrast agents, that are used to enhance image quality during the scan. If you have poor kidney function or kidney failure, your doctor may not give you the contrast as it may cause health issues.
  • If you are pregnant or think you may be pregnant, tell your healthcare provider. While MRIs are safe for pregnant women, it is necessary to discuss their benefits and risks during this time.
  • Arrive at least 15 minutes before your scheduled time, as you may be required to fill in a form and get ready for the scan.

Inform your doctor if you have any electronic devices or metal implants from previous surgeries within your body, such as:

  • Aneurysm clips
  • Pins, plates, coils, and screws
  • Prosthetic joints or limbs
  • A pacemaker
  • Artificial heart valves or stents
  • Inner ear (cochlear) implants

Metal objects can affect MRI results or pose safety issues. Your scan may be delayed or rescheduled if you fail to provide accurate information to your doctor or technologist regarding the device.

What Happens During a Knee MRI?

  • You will be asked to change into a loose gown for the test and take off everything else, including a watch, eyeglasses, hairpins, as well as, hearing aid or removable dentures.
  • The MRI machine is large, and tube-shaped with openings on both ends. You will lie on a motorized table that slides into the scanner. For a knee MRI, you will go in feet first, and only your lower body will be in the machine.
  • Your affected knee will then be placed in an MRI coil, which helps the radiologist achieve high-quality images.
  • Depending on what your physician is looking for, this test may be ordered with or without IV contrast. If your MRI is to be done with contrast, an IV line will be started in your arm or hand, in which the dye is injected.
  • The technologist will be in another room where the scanner controls are located, but they can see you through a small window. Speakers inside the scanner enable them to communicate with you and hear you. There is also a call button for you if you are not feeling well or want to pause.
  • MRI machines are usually noisy and make a lot of noise when they are working. This is normal. You will be given earplugs to block the noise, or you can also get headphones and listen to music while the scanning takes place.
  • During the scanning, the technologist may ask you to hold still for a few minutes while the machine takes images of your knee. It is important as movement can distort image quality.
  • At some point, the technologist may ask you to hold your breath for a few seconds if they are looking at something and want to focus.
  • Knee MRI can take anywhere from 30 minutes to an hour or even more, depending on what your technologist is looking for and the number of images your radiologist has requested.

MRI is a non-invasive, simple procedure and does not cause any pain. The only problem you may face is lying down for some time, especially if you have been through surgery or some other invasive procedure. Inform your technologist about your condition, and they will ensure your comfort.

What Happens After the MRI?

You can get up from the table and change your clothes. It is best to move slowly and cautiously after you have been lying down for some time to prevent lightheadedness, or dizziness and avoid further injury to your knee and leg.

If you took any anxiety-relieving medication for the procedure, you will be asked to wait until its effects have worn off before you can leave. You will need someone to drive you home. If contrast dye was used for your MRI and you experience any effects, inform your technologist. These reactions are usually mild and can be controlled with medication.

You can return to your routine diet, medication, and activities unless your doctor has advised you otherwise, depending on your knee condition and pain.

Results and Interpretation

Once the images are ready, a radiologist will analyze them and prepare the report. They will send it to your referring physician, who will share the test results with you, and explain what they mean. You can also access your report online or have the images copied onto a CD ROM for your record.

Depending on your report, your doctor will schedule a follow-up appointment to discuss more tests or a treatment plan for your knee.

Risks Associated With Knee MRI

A knee MRI does not pose any risks when safety guidelines are followed correctly, but there may be other risks based on your medical history or condition.

  • Some people have allergic reactions to the contrast dye often used during the scan. If you feel unwell after the dye is injected, or experience symptoms like hives, itching, palpitation, or breathing problems, inform your technologist immediately.
  • There may be a risk of excessive sedation if you took a relaxant or anti-anxiety medication for claustrophobia. You will be monitored till you are back to normal again.
  • Implanted devices may malfunction or get damaged in the scanner if you are not careful due to the strong magnetic field. It is essential to inform your doctor about any devices to prevent complications.
