Name of the Procedure:

Magnetic Resonance Imaging (MRI) of the Orbit, Face, and/or Neck; Without Contrast Material

Summary

An MRI scan uses strong magnetic fields and radio waves to create detailed images of the orbit, face, and neck. Unlike some imaging techniques, this procedure does not involve the use of contrast materials (dyes).

Purpose

The procedure helps diagnose medical conditions affecting the bones, tissues, and structures within the orbit (eye cavity), face, and neck. It aims to detect abnormalities, such as tumors, inflammations, infections, or other disorders.

Indications

• Persistent pain or swelling in the face, orbit, or neck
• Suspected tumors or masses
• Inflammatory or infectious conditions
• Evaluation of congenital anomalies
• Unexplained vision or nerve issues
• Pre-surgical planning

Preparation

• Patients may need to remove metal objects (jewelry, watches) and wear a hospital gown.
• No specific fasting or medication adjustments are typically required.
• A screening questionnaire may be completed to check for metal implants or devices.

Procedure Description

1. The patient lies on an MRI table that slides into the MRI machine.
2. The machine uses magnets and radio waves to generate detailed images.
3. Patients must lie as still as possible to obtain clear images.
4. The MRI machine makes loud noises; earplugs or headphones may be provided.
5. No anesthesia or sedation is needed unless the patient has significant claustrophobia or anxiety.

Duration

The procedure usually takes 30 to 60 minutes.

Setting

The procedure is performed in an imaging center or hospital's radiology department.

Personnel

• Radiology Technician: Operates the MRI machine and assists the patient.
• Radiologist: A physician who interprets the MRI images.

Risks and Complications

• Generally considered very safe with no exposure to ionizing radiation.
• Rare risks include issues for patients with certain metal implants or devices.
• Claustrophobia or anxiety during the procedure.

Benefits

• Highly detailed images of the soft tissues, bones, and structures of the orbit, face, and neck.
• Non-invasive and painless.
• Can provide crucial information for diagnosis and treatment planning.

Recovery

• No recovery time needed; patients can resume normal activities immediately.
• The radiologist will review the images and discuss results with the referring doctor.

Alternatives

• CT Scan: Faster but involves ionizing radiation and may require contrast material.
• Ultrasound: Less detailed imaging, suitable for certain soft tissue evaluations.
• X-ray: Limited detail for soft tissues, primarily used for bone imaging.

Patient Experience

• Patients might feel a sense of enclosure in the MRI machine.
• Loud noises from the MRI machine; ear protection helps reduce discomfort.
• Some may experience mild discomfort from lying still for an extended period.
• Communication with the technician is possible throughout the procedure via an intercom system.
