72148 Magnetic resonance (eg, proton) imaging, spinal canal and contents, lumbar; without contrast material

Name of the Procedure:

Magnetic Resonance Imaging (MRI) of the Lumbar Spine without Contrast Material

Summary

An MRI of the lumbar spine uses a powerful magnetic field and radio waves to produce detailed images of the structures within the lower back, including the spinal canal and its contents, without the use of contrast material. This non-invasive procedure helps in diagnosing various conditions affecting the spine.

Purpose

• Medical Condition or Problem: Herniated disks, spinal stenosis, tumors, infections, or nerve compression.
• Goals or Expected Outcomes: To obtain clear images of the lumbar spine for accurate diagnosis and treatment planning.

Indications

• Persistent lower back pain
• Sciatica or radiating leg pain
• Suspected spinal infections or tumors
• Evaluation of spinal abnormalities or deformities
• Pre-surgical planning or post-surgical assessment

Preparation

• Generally, no fasting required.
• Removal of all metallic objects (jewelry, hearing aids, etc.)
• Inform the technician of any implants, pacemakers, or metal fragments in the body.
• Sometimes, specific instructions about medication adjustments.

Procedure Description

• Step-by-Step Explanation:
  1. The patient lies on a movable examination table.
  2. The table slides into the MRI machine, a large tube-like structure.
  3. The patient must remain still during the scans.
  4. The machine generates a strong magnetic field and radio waves to create images.
  5. Images appear on a computer for radiologist review.
• Tools, Equipment, or Technology Used: MRI machine, examination table, earplugs or headphones for noise reduction.
• Anesthesia or Sedation Details: Typically none required; however, sedation may be used for claustrophobic patients.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

Performed in a hospital's radiology department or an outpatient imaging center.

Personnel

• Radiologist
• MRI Technologist
• Nurse (if sedation is required)

Risks and Complications

• Common Risks: Generally, none. MRI is considered very safe.
• Rare Risks: Allergic reactions to materials used during the procedure for specific device compatibility testing (if needed), discomfort from lying still.

Benefits

• Non-invasive and painless imaging technique.
• No exposure to ionizing radiation.
• Provides highly detailed images, aiding in accurate diagnosis.
• Immediate review of results by a radiologist.

Recovery

• No recovery time needed.
• Patients can return to normal activities immediately after the scan.
• Follow-up appointments may be scheduled to discuss results with the healthcare provider.

Alternatives

• Other Treatment Options: X-ray, CT scan, Ultrasound (depending on the condition being diagnosed).
• Pros and Cons:
  • X-ray: Quick and less expensive but provides less detail.
  • CT scan: Produces detailed images but involves radiation exposure.
  • Ultrasound: Safe option with no radiation but may not provide sufficient detail for certain spinal issues.

Patient Experience

• During the Procedure: Patient may feel slight discomfort from lying still and may hear loud thumping or tapping noises (ear protection provided).
• After the Procedure: Usual activities can be resumed immediately. Patients may discuss results with their physician at a follow-up appointment.
