Meniscal tears are a common injury in athletes but can also occur in people who are inactive. If you have a meniscal tear, an MRI scan is the best way to diagnose it.
An MRI scan is a painless procedure that uses magnets and radio waves to create detailed images of your body. It’s the best way to see whether you have a meniscal tear and how severe it is.
If you have a meniscal tear, surgery may be necessary to repair it. Getting an accurate diagnosis is the first step on the road to recovery. An MRI scan can give you that information.
How do meniscus tear MRI scans work?
When it comes to diagnosing medial meniscus tears, magnetic resonance imaging (MRI) scans can provide crucial information. This non-invasive procedure uses a powerful magnetic field and radio waves to create detailed images of the knee joint, including the meniscus. Meniscal tears often appear as dark lines in the knee MRI scan, indicating areas where the tissue has been torn. Specific meniscal tear patterns and meniscal tear configurations can also provide important information. The tear is located in the anterior cruciate ligament or medial and lateral menisci. In addition, in some cases, particularly in older patients, meniscal root tears may occur, causing severe pain and instability in the knee joint. These meniscal root tears often appear as a distinct “bucket handle” shape on MRI scans. MRI scans offer a safe and reliable method for diagnosing various types of meniscal tears and their associated meniscal tear patterns.
Why might you need a meniscus tear MRI?
Imagine you go in for a routine physical and suddenly feel extreme pain during a simple knee bend. Or perhaps you were playing your favourite sport, and twisting to catch the ball resulted in a sharp, stabbing sensation. These could be signs of a meniscus tear, often due to sudden twisting movements or forceful impact on the knee joint. Doctors may recommend a meniscus tear MRI to confirm this diagnosis and determine the extent of any damage. This meniscal imaging technique allows for clear visualization of both hard meniscal tissue, like bone, and soft meniscal tissue, like cartilage. It can also detect any fluid buildup that may indicate inflammation or injury.
There are three types of meniscal lesions: longitudinal tear, radial tear, and complex tear. Longitudinal tears often occur near the inner margin of the meniscus and run parallel to the meniscus’ blood supply. These tears typically heal well with conservative treatment, such as rest, ice, and physical therapy. Radial tears occur along the outer margin of the meniscus and cross the meniscus’ blood supply. These tears are less likely to heal on their own and may require surgery to repair. Finally, complex tears involve the meniscus’s inner and outer margins and can cross the meniscus’ blood supply. These tears are often large and require surgery to repair. Getting an early and accurate diagnosis through a meniscus tear MRI can lead to better treatment options and improved outcomes for recovery.
How to prepare for your meniscus MRI?
Preparation for a meniscus tear MRI is generally simple. You should wear comfortable clothing that doesn’t have metal buttons or zippers. You may be asked to remove any jewellery, glasses, or other objects that could interfere with the scan.
It’s important to tell your doctor if you have any metal implants in your body, such as a pacemaker or metal plate. You may not be able to have an MRI scan if you have certain types of implants.
You should also let your doctor know if you’re pregnant or think you may be pregnant. It is because magnetic resonance imaging scans use strong magnetic fields, which could harm a developing fetus. And although MRI scans are generally safe for most people, there is a small risk of allergic reaction to the contrast dye used in some scans.
If you have any concerns about the procedure, be sure to talk to your doctor or the MRI technologist before the scan.
What To Expect from an MRI scan of your meniscus?
During the scan
If you’ve been experiencing knee pain, your doctor may recommend a magnetic resonance imaging MRI scan of your meniscus. Here’s what you can expect from the procedure.
You’ll be asked to lie down on a table that slides into the MRI machine. They may place a cushion under your knee to help position it correctly. You may use straps and pillows to help you stay still during the scan.
The technologist will then move a coil around your knee. Next, it sends and receives radio waves that are used to create the images.
You may hear buzzing, clicking, and thumping noises during the scan. Earplugs or headphones with music can help reduce the noise.
The scan itself usually takes 30 to 60 minutes. But the total time for the procedure, including prep and recovery, will be about two hours.
After the scan
Once the scan is complete, you’ll be able to get off the table and go about your day. There are no side effects from having an MRI scan.
Your doctor will review the images and may recommend further testing or treatment based on what they see.
If you have a meniscus tear, treatment options may include rest, ice, and physical therapy. In some cases, you may need surgery to repair the tear.
What are the benefits of an MRI scan of the meniscus?
There are many benefits to having a magnetic resonance imaging MRI scan of your meniscus. Here are whys it can be helpful:
It’s a non-invasive procedure, meaning no needles or incisions exist.
It doesn’t use ionizing radiation, so there’s no risk of exposure to harmful radiation levels.
It can provide clear images of both hard meniscal tissue and soft meniscal tissue.
It can help your doctor detect small tears or fluid buildup around the joint.
It can help your doctor determine the best treatment option for your condition.
If you’re experiencing knee pain, talk to your doctor about whether a meniscus tear MRI scan is right for you. Getting an early and accurate MRI diagnosis can lead to better outcomes and faster recovery.
