These tests assess breathing and circulation in the lungs. As you inhale a harmless radioactive gas, the ventilation scan monitors your lungs. Next, you receive an injection of radioactive material for the perfusion scan, which monitors blood flow through your lungs. No preparations are needed, but tell your doctor if you are pregnant or breastfeeding. Your physician may also request diagnostic procedures that require sedation.
