Name of the Procedure:

• Common Name(s): Xenon Scan, Xenon-133 Gas Imaging
• Technical/Medical Term: Xenon Xe-133 Gas, Diagnostic, Per 10 Millicuries (A9558)

Summary

A Xenon-133 gas scan is a diagnostic imaging procedure that helps visualize lung function by having the patient inhale a radioactive gas, Xenon-133, which can be tracked using a special camera.

Purpose

• Medical Conditions: This procedure is primarily used to detect lung conditions such as obstructive airway disease, blood flow issues, and to assess lung ventilation and perfusion.
• Goals & Outcomes: The main goal is to obtain detailed images of the lungs to help diagnose respiratory problems and guide treatment plans.

Indications

• Symptoms/Conditions: Persistent cough, shortness of breath, chest pain, or abnormal chest X-ray findings are some indicators.
• Patient Criteria: Patients with suspected lung disease or pulmonary embolism, or those who are being evaluated for lung surgery.

Preparation

• Instructions: Patients may be required to avoid eating or drinking for a few hours before the procedure.
• Pre-assessment: No specific diagnostic tests are generally needed, but a recent medical history and physical examination may be reviewed.

Procedure Description

1. Inhalation: The patient will inhale the Xenon-133 gas while seated or lying down.
2. Imaging: A gamma camera captures images of the lungs as the gas moves through the respiratory system.
3. Observation: The patient may be asked to change positions for different images.
   • Tools & Equipment: Gamma camera, Xenon-133 gas.
   • Anesthesia: None required.

Duration

Typically, the procedure takes about 30 to 45 minutes.

Setting

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

Personnel

• Involved Professionals: Radiologist, nuclear medicine technologist.

Risks and Complications

• Common Risks: Mild discomfort from inhaling the gas.
• Rare Risks: Allergic reaction to the gas, minor radiation exposure.

Benefits

• Expected Benefits: Accurate diagnosis of lung conditions.
• Timeline: Results are often available within a few hours to a day, helping to guide timely medical decisions.

Recovery

• Post-care: Generally, no specific post-procedure care is needed.
• Recovery Time: Immediate; patients can resume normal activities right after.
• Follow-up: A follow-up appointment may be scheduled to discuss the results.

Alternatives

• Other Options: CT scan, MRI, standard X-rays.
• Pros and Cons: Alternates may be less detailed but also involve no radioactive exposure.

Patient Experience

• During Procedure: Patients might feel a bit uneasy inhaling the gas, but it’s usually not painful.
• After Procedure: Most patients feel no discomfort and require no pain management.
