73200 Computed tomography, upper extremity; without contrast material

Name of the Procedure:

Computed Tomography (CT) Scan of the Upper Extremity; Without Contrast Material

Summary

A CT scan of the upper extremity without contrast uses X-ray technology to create detailed images of structures in the arm, shoulder, and hand. This procedure does not involve the injection of contrast dye.

Purpose

The CT scan helps diagnose fractures, infections, tumors, or other abnormalities in the bones and soft tissues of the upper extremity. The goal is to provide clear and accurate images to guide diagnosis and treatment.

Indications

• Unexplained pain or swelling in the upper extremity
• Suspected fractures or bone injuries
• Infections or abscesses
• Evaluation of tumors or masses
• Assessment of structural abnormalities

Preparation

• No specific preparation is generally required.
• Patients should inform their healthcare provider of any existing medical conditions or allergies, especially to contrast material, although contrast is not used in this procedure.
• Remove any metal objects in the area being scanned.

Procedure Description

1. The patient is positioned on the CT scanner table, usually lying down.
2. The area of the upper extremity being examined is placed within the scanner.
3. The technician leaves the room but remains in contact via an intercom.
4. The scanner takes a series of X-ray images from different angles.
5. The images are processed to create cross-sectional images of the upper extremity.
6. No anesthesia or sedation is required, as the procedure is painless.

Duration

The procedure typically takes about 15-30 minutes.

Setting

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

Personnel

• Radiologist
• Radiologic technologist

Risks and Complications

• Minimal radiation exposure, though generally considered safe.
• Potential allergenic reactions to materials involved in the procedure, though very rare without the use of contrast.
• Misdiagnosis due to image limitations without contrast.

Benefits

• Provides detailed imaging to accurately diagnose conditions.
• Non-invasive with a relatively quick procedure time.
• No need for contrast eliminates the risk of contrast-related side effects.

Recovery

• No recovery time is typically needed.
• Patients can usually resume normal activities immediately after the procedure.
• Follow-up appointments may be scheduled to discuss results.

Alternatives

• X-ray: less detailed but quicker and less expensive.
• MRI: provides more detailed images of soft tissues but is more expensive and time-consuming.
• Ultrasound: useful for evaluating soft tissues and dynamic structures but less detailed for bones.

Patient Experience

• Patients may feel a bit uncomfortable lying still during the procedure.
• The room may be cool but typically blankets are provided for comfort.
• No pain is involved, and patient comfort is a priority throughout the procedure.
