Radionuclide lung imaging
Radionuclide lung imaging demonstrates pulmonary perfusion as well as the assessment of ventilation.
These studies can be both qualitative and quantitative and can distinguish between diffuse and regional pulmonary disease. The ventilation / perfusion ( V/Q) scan has the ability to display both regional airway and vascular integrity forming the basis for the non-invasive diagnosis of pulmonary emboli.

Preoperative assessment of high risk patients before planned lung resection, dead-space lung volume reduction in severe COPD, and lung transplantation
