摘要
目的探讨磁共振成像(MRI)在卵巢肿瘤定性诊断以及卵巢癌术前分期中的应用价值。方法搜集83例经病理证实的卵巢肿瘤病例,分析其MRI形态及信号特征,并与病理结果对照,评价MRI对卵巢良、恶性肿瘤诊断准确度以及卵巢癌术前分期准确度。结果 MRI清晰显示卵巢肿瘤形态学特征;同时显示肿瘤内的某些分子生物学和组织学特性。MRI对卵巢肿瘤定性诊断准确度为95.2%,良性肿瘤准确度为96.9%,恶性肿瘤准确度为85.0%;卵巢癌术前分期总准确度为73.3%。结论MRI在卵巢肿瘤定性诊断以及卵巢癌术前分期中具有重要价值。
Objective Using statistical analysis results of MRI findings in cases with ovarian tumors comparison with that of surgery and pathology,to evaluate the value of MRI in differentiating benign and malignant ovarian tumors and the value of MRI in the preoperative staging of ovarian cancer.Methods Total 83 cases with ovarian tumors proven by surgery and pathology had been reviewed and studied retrospectively. The MRI features of ovarian tumor and the MRI stages of ovarian cancer were analyzed statistically and compared with the results of pathology.Results MRI clearly show the morphological,molecular biological and histological features of ovarian tumors. The accuracy of MRI in diagnosing ovarian tumors was 95.2%, the accuracy of MRI in diagnosing benign tumors was 96.9%, the accuracy of MRI in diagnosing malignant tumors was 81%.The staging accuracy of MRI in ovarian cancer was 73.3%.Conclusion There is significant value for MRI in qualitative diagnosis of ovarian tumors and preoperative staging of ovarian cancer.
