摘　　要：目的:将螺旋CT血管成像(SCTA)技术应用于肺动脉成像,初步探讨肺血管成像的技术方法及中心型肺癌侵犯中央肺动脉(Cancerousinvasionofcentralpulmonaryarteries,CICPA)的影像学表现。方法:收集具有中央肺动脉受侵征象(CICPA)的中心型肺癌5 0例进行螺旋CT肺血管成像(SCTPA) ,扫描层厚3mm ,螺距1.5 ,重建间隔1.0～2 .0mm ,对比剂注射速度3ml/s。结果:5 0例均能直观显示肺动脉的改变。其中,34例CPA有明显行径改变,表现为CPA的僵直、移位等。4 5例CPA有管径狭窄,管腔呈管柱状向心性狭窄。12例CPA狭窄程度较重则可见外周血管的数量比对侧明显减少,延伸范围缩小。结论:SCTPA在判断中心型肺癌侵犯中央肺动脉的诊断中有重要的应用价值。Objective: Spiral CT angiography(SCTA)is used in pulmonary artery angiography in order to advance an exploitation in its methodical aspects and in the angiographic expression of cancerous invasion of central pulmonary arderies(CICPA).Methods:50 patients with CICPA were given SCTA under the parameters as collimation thickness,3mm;pitch,1.5;reconstruction interval,1.0～2.0mm;injection rate of contrast medium,3ml/s.Results:Changes of pulmonary artery could be directly shown in the 50 cases.Among them,34 were shown obvious changes in paths and courses,expressed as rigid and eccentric CPA.45 were with stenosis confliguration in different degrees,expressed as tube-like centripetal stenosis,12 were in worse shown clearly derease in the number of peripheral vessels,and reduced extension.Conclusions:SCTPA has signifilcant application value in judging the diagnosis of CICPA.
