肺动脉血栓栓塞症的多层螺旋CT诊断

Diagnosis of pulmonary embolism with multislice spiral CT

目的探讨多层螺旋CT对诊断急性肺动脉诊断的临床应用价值。方法对30例临床疑似肺动脉栓塞病例在进行肺部螺旋CT平扫后再进行多层螺旋CT肺动脉造影检查,并对原始图像进行多平面重建及三位重建。结果30例疑似肺动脉栓塞病例检出18例肺动脉栓塞。显示肺动脉内血栓部分或完全充盈缺损改变,多平面重建显示较三位重建效果更好。结论多层螺旋CT肺动脉造影检查是诊断肺动脉栓塞有效、安全、迅速的首选方法。

Objective To investigate the applicable value of multislice spiral CT in the diagnosis of acute pulmonary thromboembolism （PTE）. Methods 30 patients with clinically suspected PE were enrolled in this study.After the thorax plain multislice spiral CT scanning,multislice spiral CT pulmonary angiography（MSCTPA） was performed. Multi planar reconstruction （MPR） and surface shaded display （SSD） were carried out, Results MSCTPA demonstrated PTE in 18 patients.The embolism manifested as partial or complete intravascular filling defect. MPR was superior to SSD. Conclusion CTPA is a safe, non-invasive and effective method for the diagnosis of PTE.
