Can you tell me if there are any way to detect pulmonary embolism?

Yes: The most common way to diagnose a pe is a ct scan with dye (cta). A pulmonary arteriogram is also an excellent means of diagnosis but seldom used as it is more invasive. A nuclear medicine scan (v/q scan) may also be helpful , but, is not as definitive and gives a probably of a pulmonary embolus reported a high, low, or intermediate. A cta is by far the most popular study.
