摘　　要：目的:探讨CT纹理分析在鉴别腮腺多形性腺瘤与腺淋巴瘤中的诊断价值。方法:回顾性分析通过手术病理证实的32例腮腺多形性腺瘤与28例腮腺腺淋巴瘤的CT增强图像,并对其动脉期图像进行纹理分析,分别测得其平均值、标准差、熵值、偏度、峰度及异质性等相关参数。最后,利用多参数联合鉴别腮腺多形性腺瘤与腺淋巴瘤。结果:本研究中对腮腺多形性腺瘤与腺淋巴瘤进行纹理分析,得到各参数进行比较,可得:平均值及异质性参数在腮腺多形性腺瘤及腺淋巴瘤两组肿瘤中有较明显的统计学差异。此外,本研究对平均值、标准差、熵值等定量参数进行了多参数联合分析,对两种肿瘤的鉴别较单个参数有更明显的统计学差异。结论:CT纹理分析中平均值及异质性等参数可用于鉴别腮腺多形性腺瘤与腺淋巴瘤。Objective:To evaluate the value of CT texture analysis to differentiate parotid pleomorphic adenoma from adenolymphoma on enhanced computed tomography(CT)images.Methods:32 patients with parotid pleomorphic adenoma and 28 patients with adenolymphoma were retrospective analysed.All of these cases were proved by operative pathology and underwent CT enhancement examination.Texture analysis of CT enhancement on arterial phase was performed to obtain mean,StDev,entropy,skewness,kurtosis and inhomogenity parameters.Results:In the texture snalysis,significant difference in the mean and heterogeneity between parotid pleomorphic adenoma and adenolymphoma was found.In addition,when using multiple parameters to distinguish parotid pleomorphic adenoma from adenolymphoma,the statistical difference was more significant.Conclusion:It is of significant value to combine mean and inhomogenity of texture analysis in differentiating diagnosis between parotid pleomorphic adenoma and adenolymphoma.
