CT虚拟平扫对肺原发性淋巴组织增生性疾病的诊断价值

Diagnostic Value of CT Virtual Plain Scan for Primary Pulmonary Lymphoproliferative Disease

目的研究CT虚拟平扫对肺原发性淋巴组织增生性疾病的诊断价值。方法将本院体检的68例胸片检测疑似为肺原发性淋巴组织增生患者为研究对象,均采用CT常规平扫和双能量增强扫描。对比虚拟平扫和常规平扫的检测结果、阳性率和特异性。结果CT虚拟平扫对肺原发性淋巴组织增生性疾病诊断的灵敏度、准确度分别为92.86%、86.76%,略低于常规平扫检查的92.98%和91.23%差异无统计学意义(P>0.05);两者在疾病特异性和疾病类型诊断差异也无统计学意义(P>0.05)。结论CT虚拟平扫对肺原发性淋巴组织增生性疾病诊断准确性与常规平扫基本一致,具有较高的应用价值。

Objective To study the diagnostic value of CT virtual plain scan for primary pulmonary lymphoproliferative disease.Methods 68 cases of patients suspected as primary pulmonary lymphoproliferative disease by chest radiographs who had physical examination in our hospital were selected for the study.All patients were given CT plain and double energy enhanced scanning.The detection results,positive rate and specificity of virtual plain scan and conventional plain scan were compared.Results The sensitivity and accuracy of CT virtual plain scan with 92.86%and 86.76%were lower than those of conventional plain scan with 92.98%and 91.23%in the diagnosis of primary pulmonary lymphoproliferative disease(P>0.05).There were no significant differences in the disease specificity and disease types between the two methods(P>0.05).Conclusion The diagnostic accuracy of CT virtual plain scan for primary lymphoproliferative disease of lung is basically the same as that of conventional plain scan,and it has higher application value.
