Overview
A Magnetic Resonance Imaging (MRI) scan allows doctors to visualize internal structures without radiation. MRIs use magnets and radio waves to create detailed images, providing clear views of soft tissues. This technology is effective for detecting conditions including, but not limited to:
Disc Issues: MRI can identify herniated discs, disc bulges, and degeneration. These conditions can cause pressure on the spinal nerves and lead to pain, numbness, or weakness.
Spinal Cord and Nerve Roots: MRI provides detailed images of the spinal cord and nerve roots, helping to diagnose conditions like spinal stenosis (narrowing of the spinal canal) or nerve root compression.
Vertebral Bodies: MRI helps in assessing the vertebrae for fractures, tumors, or infections. It can also detect abnormalities in bone marrow, which can be indicative of conditions like multiple myeloma or metastatic disease.
Soft Tissues: MRI is excellent for evaluating soft tissues such as the ligaments, muscles, and the spinal cord itself, which can be crucial in diagnosing conditions like ligament tears or infections.
Congenital Abnormalities: It can also reveal congenital anomalies of the spine, such as scoliosis or kyphosis, that might be affecting the spine’s alignment or function.
Pre-Surgical Planning: For surgical planning, MRI provides a comprehensive view of the spine’s anatomy, helping surgeons understand the exact location and extent of spinal problems.
Preparation
Before you have an MRI, you will need to remove your glasses, jewelry, hearing aids, dentures and other items. People who have certain types of medical implants cannot have an MRI. You will be asked about your medical history to make sure it’s safe for you. You may be given a gown and hearing protection to wear. Medicine may be used to relax you. You may be given a special dye to drink, or given through an IV needle or other method. The dye helps the scanner see things in your body more clearly.
The Scan
To begin your scan, you will lie on a table that slides into the MRI machine, which resembles a large tube open at both ends. When the scan begins, you will hear loud banging and humming noises caused by the magnet. There are no moving parts near your body. It is crucial to remain perfectly still to ensure clear imaging. A typical scan lasts between 15 minutes to an hour. Any movement during the scan can result in blurry images and may require a repeat scan. A technician in an adjacent room will monitor you and the imaging process. They will communicate with you through a speaker to provide updates throughout the scan.
Review
After your MRI is completed, you can return home. Doctors will review the images and discuss them with you during a follow-up appointment.
