64层螺旋CT血管造影对肺动脉栓塞的临床诊断价值

目的探讨64层螺旋CT血管造影对肺动脉栓塞的临床诊断价值。方法 30例患者行肺动脉CTA检查,并采用多平面重建（MPR）对原始数据进行后处理。结果 30例均能显示肺栓塞的部位、范围及局部管腔狭窄程度,CT表现为肺动脉内不规则斑块状、附壁样缺损,周围有或无高密度对比剂包绕。结论 64层螺旋CT血管造影是临床诊断肺动脉栓塞最有效的无创性方法之一。

Clinical usefulness of 64-slice spiral CT angiography for diagnosing pulmonary embolism

Objective To evaluate the clinical usefulness of 64-slice spiral CT angiography（MSCTA） for diagnosing the pulmonary embolism（PE）.Methods thirty patients with clinically known PE underwent MSCTA.The sourse images of all the patients were postprocessed by multiplanar reconstruction（MPR）.Results MSCTA clearly showed the sites,extensions and stenosed lumens of PE in all patients.On CTA images,PE lesions appeared as intraluminal irregular-plaque shape and adhered-mural filling defects whose periphery was probably encased by the contrast medium with hyperdensity.Conclusion 64-slice spiral CT angiography is one of the most effective and non-invasive imaging modalities in the diagnosis of pulmonary embolism.
