What is a V/Q scan?

A V/Q scan is made up of two imaging checks that glance for selected lung issues. The checks are:

  • A perfusion scan, which steps circulation (how blood flows in the lungs)

The two scans may possibly be carried out independently or collectively.

A V/Q scan utilizes a compact sum of a radioactive substance named a tracer that assists glance for condition in the body. The scans help diagnose different lung situations, together with a pulmonary embolism (PE). A PE is a everyday living-threatening blockage in an artery in the lungs. It ordinarily takes place when a blood clot in a different part of the body breaks unfastened and travels to the lungs.
