目的研究卵巢肿瘤运用MRI检查的诊断价值。方法选择本院2010年9月~2012年9月间诊治的92例经手术病理确诊为卵巢肿瘤的患者,所有患者术前均进行MRI扫描,其结果与病理结果相对照。结果术前MRI检查有54例诊断为卵巢良性肿瘤,38例诊断为卵巢恶性肿瘤;术后56例诊断为卵巢良性肿瘤,36例诊断为卵巢恶性肿瘤。结论 MRI检查对组织的分辨率较好,平扫能够将病变部位、分布、大小、边界、肿瘤成分等情况清晰的显示出来,通过加权图像能够对肿瘤的良恶性进行区分。 Objective To study the diagnostic value of MRI in the diagnosis of ovarian tumors. Methods Ninety-two patients with pathologically confirmed ovarian tumors diagnosed and treated in our hospital from September 2010 to September 2012 were selected. All patients underwent MRI scanning before operation. The results were compared with the pathological findings. Results There were 54 cases diagnosed as benign ovarian tumors before operation and 38 cases diagnosed as ovarian malignant tumors. Fifty-six cases were diagnosed as benign ovarian tumors and 36 cases were diagnosed as ovarian malignant tumors. Conclusion The MRI examination of the tissue resolution is good, plain scan can clearly show the lesion location, distribution, size, border, tumor composition, etc., and the weighted images can distinguish the benign and malignant tumors.
