Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to produce detailed images of joints, ligaments, tendons, and surrounding tissues. When physical examinations cannot identify the cause of pain, physicians may recommend MRI scans to evaluate injuries and structural abnormalities. MRI examinations typically take 45 to 60 minutes, and patients usually resume normal activities afterward unless sedation is required. Here is more information about the role of MRI in diagnosing joint disorders:
Understanding MRI Technology
Magnetic resonance imaging uses powerful magnetic fields and radio waves to create detailed images of internal body structures. During the scan, magnetic fields affect hydrogen atoms in the body, while radiofrequency pulses produce signals used to generate images. Specialized sensors detect these signals, and computer software converts the information into detailed images of organs, joints, and soft tissues. Unlike X-rays, MRI does not use ionizing radiation, making it a useful imaging option for various medical conditions. Although MRI is generally safe, patients with certain implants or medical devices require additional screening before undergoing an examination.
Detecting Joint Disorders
MRI scans provide detailed images of joints and soft tissues, helping physicians identify injuries and structural abnormalities. Because certain conditions are difficult to assess through physical examinations alone, MRI offers additional information for diagnosis. Common conditions evaluated through MRI include:
- Identifying tendon injuries
- Detecting muscle injuries
- Evaluating joint damage
- Examining spinal disk abnormalities
- Identifying tumors
- Detecting torn or damaged ligaments
Physicians use MRI findings to assess the location and extent of abnormalities and guide appropriate treatment recommendations.
Undergoing the Process
During a magnetic resonance imaging examination, patients lie on a table that moves into the scanner while a technologist monitors the procedure. The machine uses magnetic fields and radio waves to capture detailed images of the targeted area. Patients must remain still throughout the scan to help produce clear images for medical evaluation.
MRI scans are generally painless and typically take between 45 minutes and one hour to complete. Although the procedure does not involve radiation, some patients may experience discomfort from remaining still or being in an enclosed space. Patients with claustrophobia should discuss their concerns with a healthcare provider before the appointment. In some cases, a mild sedative may help patients remain comfortable during the examination.
Preparing for a Scan
Preparing for a magnetic resonance imaging scan involves removing metal objects that may interfere with the machine’s magnetic field. Patients should inform their healthcare provider about medical implants, devices, or other conditions that may affect MRI safety. Common items to remove before the examination include:
- Removing jewelry
- Removing hairpins
- Removing underwire bras
- Removing eyeglasses
Before the scan, technologists review medical history and screen for implants or devices that may require special precautions. Although most patients resume normal activities immediately afterward, those receiving sedation may need additional recovery time. Patients should follow their provider’s instructions regarding preparation, medications, and transportation after the appointment.
Schedule Your Appointment
MRI scans provide detailed images of joints and soft tissues, helping physicians evaluate injuries and identify potential abnormalities. Because joint pain may have several causes, orthopedic specialists use MRI findings to guide diagnosis and treatment recommendations. Patients experiencing persistent joint pain or soft tissue discomfort may benefit from discussing imaging options with an orthopedic provider. Schedule an MRI appointment today to evaluate your symptoms and explore appropriate treatment options.
