目的探讨螺旋CT及各种三维重组技术在肺结核诊断中的价值。方法回顾性分析经病理和临床证实的肺结核病例145例,全部病例行螺旋CT扫描,针对不同病例行CTVE、MPR及CPR等不同类型三维重组。结果螺旋CT(尤其是HRCT)能够显示小叶中心结节、树芽征、结核空洞、干酪肺炎、粟粒结节、支气管播散、支气管结核、淋巴结肿大和钙化等肺结核的不同表现。螺旋CT诊断正确率为96.6%,结合各种三维重组方式后,诊断正确率99.31%。结论螺旋CT结合各种三维重组法能够对肺结核做出准确诊断。
Objective To investigate the value of spiral CT and various three-dimensional reconstruction techniques in the diagnosis of pulmonary tuberculosis. Methods We retrospectively analyzed 145 cases of pathologically and clinically confirmed cases of pulmonary tuberculosis. All cases underwent spiral CT scans and performed three-dimensional reconstruction of different types of CTVE, MPR and CPR for different cases. Results Spiral CT (especially HRCT) showed different manifestations of tuberculosis such as centrilobular nodules, dendritic spines, tuberculous cavity, pneumonia, miliary nodules, bronchial spread, bronchial tuberculosis, lymphadenopathy and calcification. The correct rate of spiral CT diagnosis was 96.6%, combined with a variety of three-dimensional reconstruction method, the diagnostic accuracy rate of 99.31%. Conclusion Spiral CT combined with various three-dimensional recombinant methods can make an accurate diagnosis of pulmonary tuberculosis.
