Gallium injection

The gallium scan is a type of nuclear scan involving radioactive gallium which helps determine whether a patient has inflammation in the lungs. Gallium is injected in a vein and a series of x-rays are taken to identify where the gallium has accumulated in the lungs. This test is most often performed when there is evidence of inflammation in the lungs (sarcoidosis).
