Lung scintigraphy is a medical imaging study into the blood flow in the lungs and the air flow in the airway of the lungs. Use is made of a radioactive substance which is brought into the body. The examination is carried out in order to detect or exclude disease processes in the lungs.
The examination provides information about any lung defects. The doctor may, for example, find a blood clot (pulmonary embolism). A lung scintigraphy can also serve as preparation for lung surgery.
Lung scintigraphy is an imaging technique, in which use is made of a radioactive substance which is administered to the patient. The radioactive substance ensures that radiation is released. This radiation can be measured. A radioactive substance has the property to accumulate at certain places in the body, for example at the location of a defect. By looking at where the radioactive substance ends up, these defects can be located.
A lung scintigraphy usually includes two parts:
The examination doesn’t hurt. Within 24 hours, the radioactive substance has disappeared from the body. This can be speeded up by drinking a lot.
