摘　　要：目的分析各种卵巢肿瘤的磁共振成像(MRI)特点,为卵巢肿瘤的确定性提供诊断依据。方法回顾分析45例经手术病理证实的卵巢肿瘤MRI表现,其中囊性肿块23例,实性肿块11例,囊实性肿块11例。结果 23例囊性肿块中,19例为良性,4例为交界性;11例实性肿瘤中有9例为良性,最常见的卵泡膜细胞瘤在T_2WI上表现为极低信号;11例囊实性肿瘤中仅1例为良性,乳头样突起和较大的软组织成分是此类肿瘤的特征性表现。结论结合卵巢肿瘤的形态学表现以及MRI信号特点,可以实现部分肿瘤的定性诊断,同时MRI为鉴别卵巢肿瘤的良恶性提供重要的信息。Objective To analyse the MRI features of ovarian tumors, to provide the criteria for making a spe- cific diagnosis. Methods Forty-five patients of ovarian tumors confirmed by operation and histopathology, 23 cases were cystic masses, 11 cases were solid masses, 11 cases were cystic and solid masses. Results Nineteen cases of cystic masses were benign and 4 cases were borderline; 9 cases of solid masses were benign, significant low signal in- tensity on Ta-weighted images was indicative of fibrothecomas; only one case was benign in cystic and solid masses, papillary projections and a large soft-tissue component are characteristic features of these tumors. Conclusions Combined with morphology and MRI signal characteristics, some specific diagnosis can be made ,MRI provides useful information for diferentiating benign from malignan tumors.
