Methods A retrospective analysis was made on clinical data of 50 pulmonary artery embolism patients， who were diagnosed by 256-slice spiral CTPA. Results There were totally 720 pulmonary arteries and branches with CTPA coloration in 50 pulmonary artery embolism patients. Direct sig of pulmonary artery embolism included complete or partial major defects， as center type， wall-attached circular type， eccentric type and block type. Involved pulmonary arteries included 80 left pulmonary arterial trunk cases， 69 right pulmonary arterial trunk cases， 198 pulmonary lobe artery cases， 301 pulmonary segment artery cases and 72 subsegment artery cases. Indirect sig were shown by CT as 4 cases with localized pulmonary texture osteoporosis and decreased lung deity； 3 cases with pulmonary infarction lesio expressing obscure trilateral coolidation shadows in inward pulmonary parenchyma flange based on pleura and pointing hilus pulmonis， partially patchy or big coolidation as non-feature in enhancement scan； 2 cases with pulmonary hyperteion expressing broadening and asymmetry central pulmonary artery； 1 case with right ventricular enlargement； 5 cases with pleural effusion. Conclusion 256-slice spiral CT contai advantages of accuracy， celerity， non-invasion， and image clarity in clinical application， and it can visually and stereoscopically show size， distribution and range of pulmonary artery embolism. This method can be taken as the preferred method in examining pulmonary artery embolism， and it is worth clinical promotion and application。 【Key words】 256-
