Lung Perfusion Scan

Lung perfusion scan is a diagnostic imaging procedure that evaluates how well blood is flowing through the lungs. It is often performed in conjunction with a lung ventilation scan to assess both airflow and blood flow in the lungs. Together, these scans are commonly known as V/Q scans. The lung perfusion scan specifically looks at the blood supply to the lungs, helping to detect conditions such as blood clots or pulmonary embolism.Lungs are crucial organs in the respiratory system responsible for oxygenating the blood. The perfusion scan involves the use of a small amount of radioactive material to highlight the blood flow in the lungs. A special camera then takes pictures of the lungs as the blood flows through them. This helps doctors to detect areas where blood flow may be decreased or blocked, which might indicate various lung diseases or conditions.

The lung perfusion scan is important for patients who have symptoms such as shortness of breath, chronic coughing, or chest pain. These symptoms may be indicative of issues with the blood flow in the lungs, and the scan can help in identifying the cause behind these symptoms.

Specific Instructions:

• Clothing: Patients are advised to wear comfortable clothing. You may be asked to change into a hospital gown.
• Medications: Inform your doctor about any medications you are currently taking, as well as any allergies.
• Fasting: Usually, there is no need to fast before a lung perfusion scan.
• Pregnancy: It is important to inform the doctor if you are pregnant or breastfeeding, as the radioactive material used may not be suitable during this time.
• You will be asked to lie down on a table.
• A healthcare professional will inject a small amount of a radioactive substance into your vein. This substance is safe and allows the blood flow in your lungs to be seen on images.
• A special camera will take pictures of your lungs as the blood flows through them. You may be asked to change positions during this time.
• The procedure typically takes about an hour.
• It helps in diagnosing lung conditions such as pulmonary embolism.
• It can be used to evaluate lung function before surgery.
• It aids in understanding the cause behind unexplained shortness of breath or chest pain.
• Patterns of blood flow in the lungs.
• Areas with reduced or blocked blood flow.
• The size and shape of the lungs and blood vessels.

Modifiable factors:

• Physical activity prior to the scan.
• Certain medications.

Non-modifiable factors:

• Lung diseases such as chronic obstructive pulmonary disease (COPD).
• History of blood clots or lung conditions.
