How can you tell if your pregnant by PE?
To diagnose PE, we use ultrasounds, CT angiography, and X-ray imaging. These tests help us find blood clots either in the lower legs or in the lungs. Some types of imaging delivers a small dose of radiation, at a level too low to harm the pregnancy.

Although CT venography is often performed in the general population, its routine use is not recommended in pregnancy due to dose concerns (,36).
What are the symptoms of pulmonary embolism (PE) during pregnancy?
In pregnant patients, the diagnosis of pulmonary embolism is complicated by normal physiologic changes during pregnancy (eg, leg swelling, pain, dyspnea, tachypnea, tachycardia, palpitations) that may mimic signs and symptoms classically associated with pulmonary embolism (, 14).
