Question

Quizplus · Accepted Answer

In a perfusion study of the lung, a radiopharmaceutical is injected intravenously and traced within the vessels of the lung, allowing for visualization of blood flow to different areas of the lung. A ventilation scan of the lung involves inhalation of a radioactive gas to visualize air flow within the lungs. Chest x-rays and CT scans provide anatomical images of the lungs but do not involve the use of radiopharmaceuticals.
