74181 Magnetic resonance (eg, proton) imaging, abdomen; without contrast material(s)

Name of the Procedure:

Magnetic Resonance Imaging (MRI) of the Abdomen without Contrast Material

Summary

Magnetic Resonance Imaging (MRI) of the abdomen without contrast is a non-invasive diagnostic procedure that uses magnetic fields and radio waves to create detailed images of the abdominal organs and tissues.

Purpose

This procedure is used to diagnose and monitor conditions within the abdomen, such as liver disease, tumors, infections, and other abnormalities. The goal is to obtain high-resolution images to assist in accurate diagnosis and treatment planning.

Indications

• Unexplained abdominal pain
• Suspicion of tumors or masses in the abdomen
• Chronic liver disease or cirrhosis
• Inflammatory bowel disease
• Abdominal infections or abscesses
• Monitoring existing abdominal conditions

Preparation

• Patients may be asked to fast for 4-6 hours before the procedure.
• Metal objects should be removed as they can interfere with the MRI.
• Inform your doctor of any implants or medical devices (e.g., pacemakers).
• Previous diagnostic images or reports should be brought to the appointment.

Procedure Description

1. The patient lies on a motorized table that slides into the MRI machine.
2. Cushions and straps may be used to ensure the patient remains still.
3. The radiologist or technician operates the MRI machine from an adjacent room.
4. The machine produces loud knocking sounds; earplugs or headphones may be provided.
5. The patient must remain still for clear images to be captured.

No contrast materials are used, so no injections are involved.

Duration

The procedure typically takes 30 to 60 minutes.

Setting

The procedure is performed in a hospital or outpatient imaging center equipped with an MRI machine.

Personnel

• Radiologist
• MRI technician

Risks and Complications

• Claustrophobia in some patients due to the enclosed space of the MRI machine.
• Rare cases of discomfort from lying still for an extended period.

Benefits

• Non-invasive with no ionizing radiation exposure.
• Provides detailed images for accurate diagnosis.
• No need for contrast material reduces risk of allergic reactions.

Recovery

• No specific post-procedure care is usually required.
• Patients can resume normal activities immediately.
• Radiologist will review the images and provide a report to your healthcare provider.

Alternatives

• Computed Tomography (CT) scan: Uses X-rays; involves radiation exposure and may require contrast.
• Ultrasound: Less detailed images but is quick and radiation-free.
• Contrast-enhanced MRI: Provides additional detail with contrast material but involves an injection.

Patient Experience

• The patient may feel some discomfort from lying still.
• Loud noises from the machine are normal and ear protection is provided.
• Most patients do not experience pain during the scan.
