摘要
目的探究肺结核的多层螺旋CT(MSCT)、磁共振(MRI)诊断及鉴别诊断价值。方法收集2017年1月~2018年12月于我院就诊并经临床病理证实的肺结核患者40例的临床资料,入组患者均自愿于我院行MSCT、MRI检查,分析两种检查方法的影像学表现,并比较影像学特征。结果 MSCT表现:平扫表现均为低密度,动态增强扫描22例表现为完全或不完全薄环状强化。MRI表现:T1WI显示均为低信号,信号不均匀,T2WI显示32例周边高信号,中央区稍低信号,DWI显示32例高信号,信号不均匀,ADC图显示稍低信号。MSCT诊断钙化的显示率明显高于MRI,但MRI诊断结核球的显示率明显高于MSCT,差异有统计学意义(P<0.05);二者在其他影像学特征显示率方面比较,差异无统计学意义(P>0.05)。结论 MSCT和MRI检查二者诊断优势不同,MSCT在钙化方面的诊断明显高于MRI,MRI在结核球的诊断上明显高于MSCT。对薄环状强化结合MRI可做出准确鉴别诊断。
Objective To explore thediagnosis and differential diagnosis value of multi-slice spiral CT(MSCT) and magnetic resonance imaging(MRI) on pulmonary tuberculosis. Methods The clinical data of 40 patients with pulmonary tuberculosis who were diagnosed in our hospitaland confirmed by clinical pathology from January 2017 to December 2018 were collected. All patients were volunteered to perform MSCT and MRI examinations in our hospital. The imaging findings of the two examination methods were analyzed, and the imaging features were compared. Results MSCT findings: plain scan showed lowdensity, and 22 cases of dynamic enhanced scan showed complete or incomplete thinring enhancement. MRI findings: T1WI showed low signal and uneven signal, and T2WI showed 32 cases of high signal in peripheral region and slightly lower signal in central region, and DWI showed 32 cases of high signal and uneven signal, and ADC showed slightly lower signal. The display rate of calcification diagnosed by MSCT was significantly higher than that by MRI, but the display rate of tuberculoma diagnosed by MRI was significantly higher than that by MSCT(P<0.05). There were no statistical significant differences in the display rates of other imaging features between the two examination methods(P>0.05). Conclusion MSCT and MRI have different diagnostic advantages. The diagnosis of calcification by MSCT is significantly higher than that by MRI, and the diagnosis of tuberculoma by MRI is significantly higher than that by MSCT. An accurate differential diagnosis can be made by thin-ring enhancement combined with MRI.
