Summary of VQ Lung Scan Video
Main Ideas and Concepts:
- A Ventilation Perfusion (VQ) Lung Scan is a nuclear medicine test that evaluates both air flow (ventilation) and blood flow (perfusion) in the lungs.
- The scan is primarily used to detect blood clots in the lungs, such as pulmonary embolism.
- The procedure involves inhaling a slightly radioactive gas and receiving a small intravenous injection of a radioactive substance to visualize lung function.
- Images are captured using a gamma camera from multiple angles to assess the distribution of air and blood in the lungs.
- The entire scan is painless, typically takes less than one hour, and involves minimal risks mainly related to radiation exposure and possible reactions to the injected material.
Detailed Methodology/Instructions:
- The patient lies on their back during the scan.
- For ventilation measurement:
- The patient breathes in a special slightly radioactive gas (Xenon or Technetium).
- For perfusion measurement:
- A small amount of radioactive material is injected intravenously.
- The patient’s bed slides into the scanner.
- A gamma camera is positioned above and below the chest.
- Multiple images are taken from different angles.
- A computer records and analyzes the flow of air and blood in the lungs.
Risks:
- Minimal radiation exposure.
- Possible reaction to the intravenous injection.
