You have had a SPECT scan of your lungs.

The examination involved injecting special materials into one of your blood vessels. The materials accumulate in particular areas of the lungs, depending on their properties. How much of the material accumulates in an area also depends on how active the cells are in the location concerned. The materials give off weak radiation for a certain time. A special camera can be used to make visible where in the body the materials have accumulated. During the scan, the special camera circulates around the body. This produces images with a spatial effect.

The SPECT scan enables a study of the air circulation in the lungs. You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result.
