软组织肿瘤MRI诊断探讨

MR diagnosis of soft tissue neoplasms

目的 :探讨MRI对软组织肿瘤定性诊断和良恶性的鉴别。方法 :回顾性分析 16例软组织肿瘤的MRI表现 ,所有病例均经手术后病理证实。其中良性 10例 ,恶性 6例。结果 :MRI定性诊断正确率 68.7% ,良恶性区分正确率为93.7% ,良性诊断正确率为 90 % ,恶性诊断正确率为 33.3%。结论 :MRI对良恶性区分诊断 ,对良性肿瘤的生物组织学定性诊断很有价值 ,对软组织肿瘤的定性诊断存在局限性 。

Objective:To evaluate the ability of MRI to characterize soft tissue neoplasms and differentiate the benign from the malignant. Methods:Correlated with pathology,the MRI findings of 16 cases,including 10 of benign tumors and 6 of the malignant, were analyzed retrospectively.Results:The accuracy of characterization was 68.7%,and the accuracy of differentiation of the benign from malignant was 93.7%.In addition,the accuracy of characterization of the benign and malignant were 90% and 33.3%,respectively. Conclusion: MRI plays an important role in differential diagnosis of benign and malignant tumors,and characterization of the benign,where as it limits its ability to characterize soft tissue neoplasms, as well as has less values in characterizing the malignant.
