Ventilation / Perfusion Scintigraphy (V/Q): It is the most sensitive method frequently used in the diagnosis of pulmonary emboli. Images are interpreted together with a recent Chest X-ray. For the interpretation BIELLO and PIOPED criteria that have been developed for this purpose are used. According to these criteria, the probability of PE is reported(eg. Low, intermediate or high probability)

Pulmonary Infections : The Ventilation/Perfusion scintigraphy is non-specific. Ga-67 or In-111 marked leukocyte scintigraphy should be preferred in equivocal cases.

Pulmonary Tumors : This method is used to predict postoperative FEV1 using the preoperative forced expiratory volume(FEV1) and segmental analysis of the lung perfusion image.

Sarcoidosis: Pulmonary Tumors: Sarcoidosis: Ga-67 is used in the diagnosis and response to the treatment. Ga-67 scintigraphy is also used for the staging and the assessment of therapy respone in lymphoma patients.
