Lung perfusion scintigraphy and lung ventilation scintigraphy

What is a lung perfusion scintigraphy and lung ventilation scintigraphy? 

A lung perfusion scintigraphy and a lung ventilation scintigraphy are two lung tests that can offer insight into any lung abnormalities you may have. The two procedures are usually done together. A lung perfusion scintigraphy is a test that shows any abnormalities in the blood flow, while a lung ventilation scintigraphy depicts the distribution of inhaled air throughout both lungs. 

In order to measure your blood flow, a small amount of radioactive substance will be administered into your bloodstream. In order to measure the ventilation, you will have to breathe in a small amount of radioactive material. We will use a gamma camera for imaging during the tests. The radioactivity will cause any damage and does not lead to side effects. 

Duration

The lung perfusion scintigraphy will take 15 to 30 minutes.
The lung ventilation scintigraphy will take 20 to 30 minutes.

After the procedure

You can go home directly after the procedure.
