Question

Quizplus · Accepted Answer

Pulmonary angiography is considered the gold standard for the diagnosis of pulmonary embolism when noninvasive studies, such as CT pulmonary angiography (CTPA) or ventilation-perfusion (V/Q) scans, do not provide a definitive diagnosis. It directly visualizes the pulmonary vasculature and can accurately identify the presence and location of emboli.
