多层螺旋CT冠状面重建图像在临床尘肺诊断中应用研究

The applied research of multislice spiral CT coronal reconstruction images in clinical diagnosis of pneumoconiosis

目的:分析多层螺旋CT冠状面重建图像在临床尘肺诊断中的应用效果,为临床诊断提供参考。方法选取我院已经确诊为尘肺患者120例为研究对象,患者分别采取高千伏胸片诊断和多层螺旋CT冠状面重建图像诊断,分析二者对尘肺诊断的差异。结果高千伏胸片发现可疑病例30例,MSCT未出现可疑病例,高千伏胸片显示可疑病例比例(25.0%)。MSCT和高千伏胸片对尘肺征象显示能力存在显著差异,P<0.05,MSCT对小阴影聚集、胸膜下透光带、肺门及纵膈淋巴结钙化、大阴影内部结构等显示能力显著高于高千伏胸片组,P<0.05,两种诊断方法对尘肺阴影密集度>1的显示无明显差异,P>0.05。MSCT组诊断出并发症比例显著高于高千伏胸片组,P<0.05。结论在尘肺诊断中,采用多层螺旋CT冠状面重建图像具有明显优势,比高千伏胸片诊断结果更加可靠。

Purpose： To analysis the applied research of multislice spiral CT coronal reconstruction images in clinical diagnosis of pneumoconiosis. Materials and Methods： 120 patients with Pneumoconiosis diagnosis in hospital were selected.Patients were taken diagnose of High kilovolt chest diagnosis and multislice spiral CT coronal reconstruction images,two diagnostic results were analyzed. Results： High kilovolt chest found 30 cases of suspected cases,MSCT diagnose suspected cases was not appear,high kilovolt chest radiograph the proportion of suspected cases（ 25. 0%） was significantly higher than MSCT group（ 0）,P〈0. 05. High kilovolt chest and MSCT signs of pneumoconiosis display were significantly different capability,P〈0. 05,MSCT small shadows gather,the photic zone,hilar and mediastinal lymph node calcification,large internal structure under the shadow of the pleura and other display capability were significantly higher than high kilovolt chest group,P〈0. 05,two diagnostic methods was no significant difference in Pneumoconiosis shadow density 1,P〈0. 05. MSCT group diagnosed with complications was significantly higher than the proportion of high kilovolt chest X- ray group,P〈0. 05. Conclusion： In pneumoconiosis diagnosis,using multi- slice CT coronal reconstructed image has obvious advantages,is high kilovolt chest diagnosis more reliable.
