CT技术与MR技术对眼眶良恶性肿瘤的鉴别作用及影像特征比较

Comparison of Effect and Imaging Features of CT and MR Techniques in Distinguishing Benign and Malignant Tumors of Orbit

目的比较CT、MR鉴别眼眶良恶性肿瘤的作用与影像学特征表现。方法回顾分析2016年12月—2021年12月本院收治的34例眼眶肿瘤患者基础资料,所有患者均接受CT与MR检查,参照手术病理结果比较两种检查的诊断价值与影像学特征。结果手术病理确诊良性肿瘤21例(61.76%),恶性肿瘤13例(38.24%);CT与MR的诊断灵敏度、特异度、准确度之间差异无统计学意义(P>0.05);良性组与恶性组相比,病灶部位、大小、累及象限间差异无统计学意义(P>0.05)。形态、边界、位置以及骨质破坏情况组间比较存在显著差异表现(P<0.05);良性组与恶性组T2信号组间比较存在显著差异表现(P<0.05)。T1信号、T1信号均匀性、T2信号均匀性、强化方式以及CT值未见显著性组间差异(P>0.05)。结论将CT、MR技术应用于眼眶肿瘤性质的鉴别工作中,可显示出良好的诊断价值。

Objective To compare ef fect and imaging features of CT and MR in distinguishing benign and malignant orbital tumors.Methods The paper reviewed and analyzed basic data of patients with orbital tumors with CT and MR examinations from December 2016 to December 2021,compared diagnostic value and imaging features of two examinations based on surgical pathological results.Results There were 21 cases(61.76%)of benign tumors and 13 cases(38.24%)of malignant tumors based on surgical pathology among 34 cases,there was no significant statistical difference for diagnostic sensitivity,specificity,and accuracy of CT and MR,(P>0.05),no significant statistical difference between benign group and malignant group in terms of lesion location,size,and affected quadrants(P>0.05),there was significant difference in morphology,boundaries,location,and bone destruction between groups(P<0.05),there was significant difference in T2 signal expression between benign group and malignant group(P<0.05),there was no significant intergroup comparison difference(P>0.05)in T1 signal,T1 signal uniformity,T2 signal uniformity,enhancement mode,and CT value.Conclusion CT and MR techniques can achieve good diagnostic value in distinguishing nature of orbital tumors.
