Correct Answer � A Explanation

Ans:A.)Pulmonary Embolism

VENTILATION -PERFUSION SCAN

Clinical Indications:

• Pulmonary Embolism
• Assessment prior to lung reduction surgery
• This test can be performed on patients who are not suitable for CTPA due to an iodine allergy

The V/Q scan is the recommended test for exclusion of PE in women of child-bearing age, as the radiation exposure to the breasts is much lower than a CTPA.
