In brief: Inject radioactive
A perfusion lung scan is done by injectecting a low-dose radioactive tracer into a vein and taking images showing where blood flow is going in the lungs.
It is used to diagnose pulmonary embolism (blood clot to the lungs). The test is safe and generally free of any side effects. It is used less often now than ct angiogram, but is safer and involves less radiation exposure.

In brief: The V/Q Scan
The pulmonary v/q scan is primarily used to evaluate for pulmonary embolism.
This involves imaging blood perfusion to the lungs as well as ventilation to the lungs.
