RADIOISOTOPE DIAGNOSTIC PROCEDURE:

Radioisotope diagnostic procedures include perfusion, ventilation  and gallium scan.
Perfusion Lung Scan
Following  injection of a radioactive isotope, scans are made with a  scintillation
camera.
1)  Measures blood perfusion  through the  lungs; evaluates lung function on a regional basis.
2)  Useful in perfhion  (vascular) abnormalities-pulmonary embolism.

Ventilation  Scan 
1)  Inhalation of radioactive gas (xenon, krypton), which diffuses throughout the lungs.
2)  Useful  in detecting ventilation abnormalities (emphysema).

Gallium Scan

Radioisotope  lung scan used  to detect inflammatory conditions of the lungs.
