| 摘 要： | 目的研究胸部CT平扫在临床急性肺栓塞中的诊断意义。方法分析110例肺栓塞(PE)CT平扫的患者,依据肺部梗塞面积的大小对急性肺栓塞患者进行影像学分类:大面积和次大面积共70例,非大面积40例。结果研究组的CT征象中,无梗死性肺部炎症病变的改变清楚,对于那些经典的楔形影、马赛克征等的影象学征象却表现不明。大面积和次大面积的肺栓塞与非大面积肺栓塞的临床CT表观征象比较差异均无统计学意义(P>0.05)。结论肺梗塞和非梗塞的病理变化在临床CT征象上表现相似,两者比较无特异性CT征象,两者容易误诊,甚至漏诊。

| Abstract: | Objective To study the clinical significance of chest CT plain scan in the diagnosis of acute pulmonary embolism.Methods The imaging characteristics of 110 patients with pulmonary embolism（PE） treated with CT plain scan were retrospectively analyzed.According to the size of pulmonary infarct,they were divided into the group A with large and adah area（70 cases） and the group B with non-large area.Results The pathological changes of no infarction lung inflammation were clearly reflected through CT plain scan,but for those classic wedge shadow and Mosaic sign,CT image didn＇t show clearly.The difference of CT image had no statistical significance between the two groups（P〈0.05）.Conclusion The pathological changes of pulmonary embolism and non-pulmonary embolism have similar CT plain scan signs,so it is very easy to be misdiagnosed. |
