Abstract:
Objective To evaluate the clinical application of spiral CT pulmonary angiography(SCTPA) in the diagnosis of pulmonary embolism(PE) and its limitation.Methods 52 cases of PE were analyzed.SCTPA were performed in all cases with slice thickness 3 mm,pitch 1.5~2.0,scanning time 0.8 s,reconstruction thickness 1mm.The reconstructions of SCTPA included MIP,MPR and SSD.Results 2898 pulmonary arteries in 52 cases were observed.The direct manifestations of PE were showed in 927 pulmonary arteries(32.0%) by SCTPA,in which superior segmental and inferior segmental of pulmonary arteries were involved respectively.The indirect manifestations of PE were showed by plain scan in 113 cases.Conclusion SCTPA is a high effective and noninvasive method in the diagnosis of PE especially for the PE of superior segmental.
