What is a V/Q scan?
A V/Q scan consists of two imaging tests that appear for specified lung issues. The tests are:
- A ventilation scan, which measures how air moves in and out of your lungs
- A perfusion scan, which measures circulation (how blood flows in the lungs)
The two scans may well be finished individually or alongside one another.
A V/Q scan employs a smaller quantity of a radioactive material identified as a tracer that will help appear for illness in the system. The scans aid diagnose diverse lung disorders, which include a pulmonary embolism (PE). A PE is a existence-threatening blockage in an artery in the lungs. It generally transpires when a blood clot in yet another section of the system breaks free and travels to the lungs.
Other names: ventilation/perfusion scan, pulmonary ventilation/perfusion scan, lung scan, lung V/Q scan
