V/Q scan; Ventilation/perfusion scan; Lung ventilation/perfusion scan
Normal Values
The health care provider should take a ventilation and perfusion scan and then evaluate it with a chest x-ray. All parts of both lungs should take up the radioisotope evenly.
What abnormal results mean
If the lungs take up lower than normal amounts of radioisotope during a ventilation or perfusion scan, it may be due to:
Airway obstruction - Chronic obstructive pulmonary disease (COPD)
Pneumonia - Narrowing of the pulmonary artery
- Pneumonitis
- Pulmonary embolus
- Reduced breathing and ventilation ability
