摘　　要：目的探讨CT多平面重建技术(MPR)对叁期尘肺及并发症的诊断价值。方法于2020年9月,选择广州市第十二人民医院94例叁期尘肺患者进行数字化X线摄影(DR)检查和MPR检查,对大阴影检出率及有关并发症发生情况进行对比分析。计数资料用频数及百分比(%)表示,比较用χ2检验。结果患者MPR和DR胸片分别检出大阴影178、132个,与DR检查比较,MPR对肺结核、肺气肿、胸膜增厚和黏连、肺门及纵膈淋巴结增大和钙化、气胸、胸腔积液和肺炎等尘肺相关并发症的检出率均较高,差异均有统计学意义(P<0.05),对肺大泡的检出率差异无统计学意义(P>0.05)。与DR检查比较,MPR对空洞、钙化、支气管扩张、瘢痕旁气肿征象的诊断检出率更高,差异均有统计学意义(P<0.05)。结论MPR对叁期尘肺大阴影及并发症的检出效果较好,具有一定的应用价值。Objective To investigate the value of CT multiplanar reconstruction(MPR)in the diagnosis of stageⅢpneumoconiosis and complications.Methods In September 2020,94 patients with stageⅢpneumoconiosis in Guangzhou 12th people's hospital were selected for digital radiography(DR)and MPR.The detection rate of the number of large shadows and the incidence of related complications were compared and analyzed.The counting data were expressed by frequency and percentage(%),and the comparison was performed by chi square test.Results 178 and 132 large shadows were detected in MPR and DR chest films respectively.Compared with Dr examination,MPR had higher detection rates of pneumoconiosis related complications such as pulmonary tuberculosis,emphysema,pleural thickening,adhesion,pneumonia,pleural effusion,enlargement of hilar and mediastinal lymph nodes and calcification(P<0.05),There was no significant difference in the detection rate of pulmonary bullae(P>0.05).Compared with Dr,MPR had a higher detection rate in the diagnosis of cavity,calcification,bronchiectasis and parascar emphysema(P<0.05).Conclusion MPR is better in detecting large shadow and complications of stageⅢpneumoconiosis,and has important value.
