Name of the Procedure:

Magnetic resonance imaging (MRI) of the upper extremity, other than joint; without contrast material(s). Commonly referred to as an Upper Extremity MRI.

Summary

An Upper Extremity MRI is a non-invasive imaging procedure that uses magnetic fields and radio waves to produce detailed images of the structures in the upper limb, such as muscles, tendons, and blood vessels, without the need for contrast dyes.

Purpose

This procedure is primarily used to diagnose or evaluate conditions affecting the upper extremities (arms). It helps identify injuries, abnormalities, or diseases of the muscles, tendons, nerves, and blood vessels. The goal is to provide a comprehensive view that aids in accurate diagnosis and guides treatment planning.

Indications

• Persistent pain or swelling in the upper extremity
• Suspected soft tissue injuries (e.g., muscle tears, tendonitis)
• Evaluation of nerve impingement or damage
• Detection of tumors or cysts
• Assessment of vascular conditions like deep vein thrombosis (DVT)

Preparation

• No special preparation is usually required.
• Patients should remove any metal objects, such as jewelry and watches.
• Inform the technician if you have metal implants, pacemakers, or claustrophobia.
• Some basic diagnostic tests or health assessments may be conducted to ensure suitability.

Procedure Description

1. The patient will lie down on the MRI table.
2. The targeted upper extremity will be positioned inside the MRI machine.
3. The machine uses a powerful magnetic field and radio waves to capture detailed images.
4. The patient must remain still during the imaging to ensure clear pictures.
5. The entire procedure is painless and typically doesn’t require sedation or anesthesia.

Duration

The procedure usually takes between 30 to 60 minutes.

Setting

This procedure is typically performed in the radiology or imaging department of a hospital or an outpatient clinic specialized in imaging services.

Personnel

• Radiologist or MRI technician conducting the procedure
• Radiologist who will interpret the images

Risks and Complications

• Rare risk of discomfort due to lying still
• Slight chance of reactions in patients with undiagnosed metal implants or conditions
• MRI is considered very safe; no radiation exposure is involved

Benefits

• Provides highly detailed images of soft tissues
• Non-invasive with no recovery time required
• Helps in accurate diagnosis leading to effective treatment planning

Recovery

• No recovery time needed; normal activities can be resumed immediately
• Follow-up appointments may be scheduled to discuss results with your doctor

Alternatives

• X-rays for bone-related conditions
• CT scans for a different type of imaging, though it involves radiation exposure
• Ultrasound for evaluating soft tissues and blood flow

Patient Experience

• The patient may hear loud thumping or tapping sounds from the machine; earplugs or headphones might be provided.
• Comfort measures such as cushioning and blankets are provided to help the patient remain still and comfortable.
• Most patients experience no pain; slight discomfort from lying still may occur.
