Magnetic resonance (eg, proton) imaging, spinal canal and contents, thoracic; without contrast material
CPT4 code
Name of the Procedure:
Magnetic Resonance Imaging (MRI) of the Thoracic Spine without Contrast Material
Summary
An MRI of the thoracic spine is a non-invasive imaging procedure that uses magnetic fields and radio waves to create detailed images of the spine and the surrounding tissues. This procedure focuses specifically on the thoracic region, which is the section of the spine between the neck (cervical spine) and the lower back (lumbar spine), without using contrast material.
Purpose
MRI of the thoracic spine is used to diagnose various spinal conditions, including herniated discs, spinal cord tumors, spinal infections, and degenerative disc disease. The goal is to obtain high-resolution images that provide detailed information about the spinal canal and surrounding structures, aiding in accurate diagnosis and treatment planning.
Indications
- Persistent back pain in the thoracic region.
- Symptoms of nerve compression such as numbness, tingling, or weakness in the arms or legs.
- Suspected spinal cord tumors or infections.
- Degenerative diseases of the spine.
- Traumatic injury to the thoracic spine.
Preparation
- No fasting required.
- Patients should inform their healthcare provider of any metal implants, pacemakers, or claustrophobia.
- Wear comfortable clothing without metal zippers or buttons.
- Remove all jewelry or metal objects.
Procedure Description
- The patient lies down on a motorized bed that slides into the MRI machine, a large tube-shaped magnet.
- Cushions and straps may be used to maintain the correct position and stay still during the scan.
- The MRI machine uses magnetic fields and radio waves to capture detailed images of the thoracic spine.
- The procedure involves multiple scans and the machine may make loud thumping noises.
- The patient will be given earplugs or headphones to block out the noise.
- Throughout the scan, a technician monitors the patient from another room and communicates via intercom.
Duration
The entire procedure typically takes between 30 to 60 minutes.
Setting
MRI procedures are usually performed in a hospital imaging department or an outpatient imaging clinic.
Personnel
- Radiologic Technologist: operates the MRI machine.
- Radiologist: interprets the images.
- Occasionally, a nurse or technician may assist with positioning and monitoring the patient.
Risks and Complications
- No known risks from the MRI itself, as it does not use ionizing radiation.
- Rarely, patients may experience discomfort from lying still or anxiety from being in an enclosed space.
Benefits
- Non-invasive with no exposure to ionizing radiation.
- Provides highly detailed images of soft tissues, bones, and nerves.
- Aids in accurate diagnosis and effective treatment planning.
- Can help avoid the need for exploratory surgery.
Recovery
- No recovery time needed.
- Patients can resume normal activities immediately after the procedure.
- Follow-up consultations are typically scheduled to review MRI results with the healthcare provider.
Alternatives
- X-rays: less detailed, and involve radiation exposure.
- CT scans: more detailed than X-rays but involve ionizing radiation.
- Myelography: uses X-ray and contrast dye to visualize the spinal cord and is more invasive.
Patient Experience
- The patient might feel a bit anxious due to the enclosed MRI machine; however, comfort measures such as earplugs and communication with the technologist can ease this.
- Most patients report no pain during the procedure.
- Any discomfort from lying still is minimal and temporary.
