| 摘 要： | 目的:探讨64层CT肺动脉造影(CTPA)对肺栓塞的诊断效果及治疗后复查的价值。方法:对32例肺动脉栓塞的患者采用64层CT行CTPA检查,并进行多平面重建(MPR)、最大密度投影及容积重建处理。患者复查采用相同CT检查及后处理重建。结果:32例患者中15例有下肢静脉栓塞、4例有恶性肿瘤、3例有近期手术病史,2例有近期外伤史。CTPA对肺动脉主干、左右肺动脉及叶、段、亚段动脉显示良好,32例患者中显示受累肺动脉221支,其直接征象为肺动脉血管内充盈缺损,间接征象包括肺梗死实变、肺野少血征、胸腔积液等。肺栓塞治疗后复查有24例患者1月内肺动脉栓子消失或明显吸收缩小(占75%);6例患者吸收不明显(占18.7%);2例死亡。结论:64层CT能清楚地显示肺栓塞的形态、部位及其它间接征象,并能有效监测治疗效果,为临床提供有益帮助。

| Abstract: | Objective:To explore the value of CT pulmonary angiography(CTPA) with 64-slice CT in the diagnosis of pulmonary embolism(PE) and follow-up after treatment.Methods:Thirty-two patients with PE were examined with CTPA by 64-slice CT and processed multiple planar reconstruction(MPR),maximum intensity projection(MIP),and volume reconstruction(VR).All the follow-up was subjected to the same CT examinatoin and reconstruction.Results:Of 32 cases,15 cases had deep venous thrombosis(DVT),4 cases had malignant tumor,3... |
