Abstract：To evaluate the efficacy and technique of spiral CT in the diagnosis of pulmonary embolism(PE). Materials and Methods: Two hundred and forty-nine consecutively registered patients with clinically suspected of PE were analyzed retrospectively. The technique of sprial computed tomography pulmonary angiography(SCTPA) and the appearance of PE were studied. Results: The peak time of enhancement in aorta is about 10.8s. There were 68 patients and 705 pulmonary arteries with embolism, including eccentric embolism in 506 pulmonary arteries(71.8%), centric embolism in 147 pulmonary arteries(20.8%), wall thickened in 19 pulmonary arteries(4.7%) and complete obstruction in 33 pulmonary arteries(2.7%). The other 181 had no PE. But there were other pulmonary lesions found in 105 patients. Conclusion: SCTPA is important in diagnosing PE, and it can detect other pulmonary lesions simultaneously. In patients with clinical suspicion of PE, SCTPA is the primary imaging technique.
