能谱CT在不典型结核球与肺癌中的诊断价值

Diagnostic Value of Spectral CT in Atypical Tuberculoma and Lung Cancer

目的:探究能谱CT在诊断不典型结核球与肺癌中的诊断价值。方法:回顾性分析我院2014年7月-2015年2月采用能谱CT扫描并经过病理确诊的不典型结核患者与肺癌患者40例,按随机数字表法分为观察组20例,对照组20例。其中观察组为不典型结核球患者,对照组为肺癌患者。观察两组患者采用能谱CT扫描后测得的两组动脉期碘、水含量及有效原子序数,计算出能谱曲线的斜率。结果:碘浓度、有效原子序数、能谱曲线斜率分别为0.82、0.86、0.89。结论:采用能谱CT诊断不典型结核球与肺癌,诊断价值显著,值得推广应用。

Objective: To discuss the diagnostic value of spectral CT in atypical tuberculoma and lung cancer. Methods: The clinical data about 40 patients of being pathologically proved as atypical tuberculoma and lung cancer from July 2014 to February 2015 in our hospital was analyzed. The subjects were randomly assigned to observation group(atypical tuberculoma, n=20) and control group (lung cancer, n=20). Results: The AUC(area under the curve) of iodine contents, effective atomic number and spectral curve slope was 0.82, 0.86 and 0.89. Conclusion: The spectral CT has an obvious effect in the diagnosis of atypical tuberculoma and lung cancer. It is worthy of clinical promotion and application.
