MRI scanning may be necessary if you have a knee injury or experience pain, weakness, or swelling around your knee. Doctors can use this test to determine if your symptoms are related to a medical condition. MRI scans create detailed images of the inside of the body by using a magnetic field, radio waves, and a computer. A knee MRI scan shows your doctor all your bones, cartilage, tendons, ligaments, muscles, and even some blood vessels, unlike an X-ray whic shows just bones.
Let's find out more about MRI scanning for a knee injury, why you should get an MRI scan, and what it takes to prepare for the MRI scanning process.
Knee MRI Scanning:
Magnetic resonance imaging is also known as MRI. Magnetic fields and radio waves are used in an MRI test to capture images inside the body without having to make an incision. MRI can be done on any part of the body. However, your knee and its surroundings are the focus of a knee MRI scanning.
Your doctor can observe both the bones and soft tissues in your body using an MRI. This enables them to examine any parts of the knee that might have been injured by exercise or normal wear and tear. In-depth images of the knee's numerous components, including its bones, cartilage, tendons, muscles, blood vessels, and ligaments, can also be obtained from the examination. Compared to other examinations, an MRI produces images with superior contrast.
How is MRI Scanning Better than X-ray?
In comparison to an X-ray, an MRI scan is significantly more effective at identifying damage and issues with the knee. It produces precise and in-depth images of the inside of the body from numerous angles using radio waves and a powerful magnetic field. Contrarily, an X-ray uses radiation to create a single, plain image.
An MRI can reveal things like bone anomalies, cartilage degeneration, and ligament or tendon tears. Additionally, it can be used to find malignancies or infections. While a knee X-ray is useful for spotting fractures or other bone damage, it does not reveal as much information about soft tissues as an MRI.
Therefore, it is strongly advised that you obtain an MRI scan to identify the source of any knee pain or stiffness.
Right Time to Get MRI Scanning
When it comes to assisting you in getting rid of your knee discomfort, magnetic resonance imaging is particularly important. But when should you have your knee MRI'd? If your doctor suspects any problems within your knee joint, they may request an MRI scan. Without doing surgery, the test enables your doctor to see the structure of your knee and identify any potential causes of your pain, inflammation, or weakness.
Typically, a doctor may prescribe an MRI to aid in the diagnosis and treatment of various illnesses. These consist of:
• Other degenerative joint diseases, such as arthritis
• Broken bones
• Injured meniscus, ligaments, tendons, or cartilage
• Knee joint motion is lessened.
• Swelling in the knee
• Issues with implanted medical technology
• Trauma or sports-related injuries
Along with your knee MRI, your doctor might also request further imaging exams, such as an X-ray. In addition, before undergoing knee arthroscopy, they could place an MRI request. A small incision is made, and a scope with a camera is inserted to allow the doctor to see into your knee.
Risks Associated With MRI Scanning
Radiation is not used in an MRI, in contrast to X-rays and CT scans. Everyone agrees that it's a safer option, especially for kids and expectant mothers. The radiation levels in CT scans are tolerable for adults, but they must be used carefully on youngsters and are not safe for growing fetuses.
You run some dangers if you have metal-containing implants. Pacemakers and surgically implanted screws or pins may shift as a result of the MRI's magnets. The contrast dye used in MRIs may cause an allergic reaction in certain persons. Gadolinium is the most popular kind of contrast dye. However, the medicine may usually be used to easily treat these moderate allergic reactions.
Things To Do To Prepare for MRI Scanning
Now that you know what MRI scanning is, how it is different from X-rays, and the risks associated with MRI scanning, it's time to prepare for Knee MRI scanning.
1. Every testing facility has its own unique MRI preparation procedures. You will receive comprehensive instructions on how to be ready for your particular test from your doctor or the attending technician.
2. Your clinician will thoroughly examine you and take a detailed medical history before performing an MRI. Inform them about all of your prescription, over-the-counter, and herbal supplements that you are using. Include any known allergies as well. If you have any medical devices that have been implanted, let them know since the test may impact them.
3. Inform your doctor if you've ever experienced an adverse reaction to contrast dye or if you've been given a kidney-related diagnosis.
4. If you're nursing or afraid that you could be pregnant, let clinicians know. For pregnant women, radioactive contrast dye used in MRIs is not regarded as safe. Mothers who are nursing should stop nursing for roughly two days after the test.
5. It is a small, enclosed area inside the MRI scanner. Be sure to discuss your choices with your doctor if you suffer from claustrophobia or a fear of confinement. They might administer a sedative to help you unwind. If you suffer from extreme claustrophobia, your doctor might recommend an "open" MRI. This kind of MRI uses a machine without a body-enclosing enclosure.
How Does an MRI Scanning Work?
An MRI machine resembles a massive wheel. A flat table can glide in and out of the machine because the middle portion of the MRI machine is left open for sliding. The magnetic and radio waves used to create photographs of your body are sent out by the rounded, wheel-like portion.
On a cushioned table, you will lie on your back or your side. To make your knee more relaxed during the test, the technician may utilize straps or pillows. As a result, the machine will be able to capture the clearest photos while keeping your leg immobile.
The operator will next lower you, feet first, into the apparatus. You'll be told when to remain motionless and hold your breath. Since the operator will be in a different room observing the monitors as they gather images, these directions will be delivered over a microphone.
Although you won't feel the machine in action, you might hear some loud noises like clacks or thuds, as well as possibly a whirling sound. You might receive earplugs or some music from the operator. During the scan, there won't be any sensation. However, if this is your first MRI, you could be taken aback by how noisy it is. The device emits humming, banging, and knocking noises. You'll probably be given headphones or earplugs by the techie. If not, you can request them.
The inspection normally lasts 30 to 60 minutes. You can change back into your clothing and resume your day once the technician has captured the necessary photographs. Following the examination, the technician will transmit pictures to a radiologist, who will then send your doctor a report. You'll be able to take your car home and get on with your day as usual.
How Does It Feel to Go Through Knee MRI Scanning?
An MRI scan is painless. You must remain still as you lay there. Abrupt movement can affect MRI results and produce mistakes. You can request a blanket or pillow even if the table is uncomfortable or cold. When turned on, the device emits a loud thumping and humming sound. You can reduce noise by donning earplugs.
You can communicate with everyone in the room at any moment, thanks to the intercom. To pass the time, some MRI machines feature televisions and specialized headphones. If you weren't given a medication to relax you, there is no recuperation period. You can resume your regular diet, exercise, and medication regimen after having an MRI.
Post Knee MRI Scanning
Your physician will receive the results of the radiologist's examination of your Knee MRI scans. MRI scans come in monochrome. Bright white specks could be an abnormality. These show regions where the contrast dye has accumulated as a result of increased cell activity.
Your doctor will discuss the issue and the subsequent measures for therapy after reviewing the test findings. Your condition will determine if you need additional testing, medication, physical therapy, surgery, or a combination of these. The ideal approaches for you will be determined with the advice of your doctor.
MRI scanning is the best viable option for anyone suffering from a knee injury or any other knee-related problems. MRI scanning provides a detailed image of the body parts. If you are suffering from a knee injury, then contact Wessex Knee Surgery to get an MRI scan of your knee.
