72142 Magnetic resonance (eg, proton) imaging, spinal canal and contents, cervical; with contrast material(s)

Name of the Procedure:

Magnetic Resonance Imaging (MRI) of the Spinal Canal and Contents, Cervical with Contrast Material(s)

Summary

An MRI of the cervical spine with contrast is a diagnostic imaging procedure that uses magnetic fields and a contrast dye to create detailed images of the spinal cord, vertebrae, and surrounding tissues in the neck area.

Purpose

The procedure is used to identify abnormalities or injuries in the cervical spine, such as herniated discs, spinal stenosis, tumors, or infections. The contrast material helps to enhance the visibility of certain tissues and structures, allowing for a more accurate diagnosis.

Indications

• Chronic neck pain or stiffness
• Suspected nerve compression or damage
• Unexplained numbness, tingling, or weakness in the arms or hands
• Assessment of spinal tumors or infections
• Monitoring conditions such as multiple sclerosis or spinal cord injuries

Preparation

• Patients may need to fast for a few hours prior to the procedure.
• Any metal objects should be removed before the scan starts.
• Inform the healthcare provider of any allergies, especially to contrast dye.
• Patients with kidney issues may need a blood test to assess kidney function before receiving the contrast material.

Procedure Description

1. The patient lies down on the MRI table.
2. An intravenous (IV) line is inserted into the arm to administer the contrast dye.
3. The table slides into the MRI machine, which is a large, cylindrical scanner.
4. The patient is required to stay still while the machine takes images.
5. The technician may provide earplugs or headphones to muffle the loud knocking noises produced by the MRI machine.
6. The contrast material is injected mid-procedure to obtain enhanced images.
7. Additional images are captured after the contrast is administered.

Duration

The procedure typically takes about 45 to 60 minutes.

Setting

The procedure is performed in a hospital or an outpatient imaging center.

Personnel

• Radiologist or MRI technologist to operate the MRI machine and monitor the procedure.
• Nurse or technician to administer the contrast dye.

Risks and Complications

• Rare allergic reactions to the contrast material.
• Slight risk of kidney damage from the contrast dye, particularly in patients with pre-existing kidney issues.
• Claustrophobia or discomfort due to the confined MRI machine space.
• Temporary discomfort at the injection site for the contrast dye.

Benefits

• Detailed and accurate imaging of the cervical spine and surrounding tissues.
• Non-invasive with no radiation exposure.
• Enhanced detection and diagnosis of spinal conditions.

Recovery

• Most patients can resume normal activities immediately after the procedure.
• Drink plenty of fluids to help flush out the contrast dye.
• Follow-up appointments may be scheduled to discuss the results with your healthcare provider.

Alternatives

• CT Scan: Utilizes X-rays and may be quicker but involves radiation exposure and may not provide as detailed images.
• X-ray: Primarily useful for assessing bone structures but less effective for soft tissues.
• Ultrasound: Limited in its ability to image spinal structures and not commonly used for spinal issues.

Patient Experience

• Patients may feel slight pressure from the IV insertion and a cold sensation when the contrast dye is injected.
• The MRI machine may be noisy, but ear protection is provided.
• Mild anxiety or claustrophobia can occur due to the enclosed space; some facilities offer relaxation techniques or sedation for comfort.
