Final answer:

A lung ventilation scan performed with Xenon has the advantage of matching perfusion and ventilation positioning. It can detect delayed washout and can be performed at the patient's bedside. It can also perform perfusion before ventilation without increasing the radiation dose.

Step-by-step explanation:

A lung ventilation scan performed with Xenon has the advantage of being able to match perfusion and ventilation positioning. This means that the scan can accurately assess both the blood flow and air distribution in the lungs, providing a more comprehensive evaluation of lung function.

Additionally, the use of Xenon allows for the detection of delayed washout, which can be indicative of certain lung diseases or abnormalities.

Furthermore, the exam can be performed at the patient's bedside, eliminating the need for the patient to be transported to a specialized imaging facility.

Lastly, Xenon ventilation can be performed before perfusion without increasing the radiation dose given for the ventilation study, providing valuable diagnostic information while minimizing potential risks.
