Final Answer :
D
Explanation :
Scintiphotography, also known as a lung ventilation/perfusion scan, is the preferred test for evaluating ventilation and perfusion in order to detect a pulmonary embolus. CT, MRA, and PET can also be used to assess for a pulmonary embolus, but they are typically reserved for cases where scintiphotography is inconclusive or unavailable.
