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
