【摘要】：MRI凭借多方位成像和良好的组织对比度,在评价卵巢肿瘤的良恶性时具有重要的诊断价值。然而,鉴别原发卵巢恶性肿瘤(POMT)和转移瘤(MOT)的特异性MRI征象尚未见报道。MOT占所有卵巢恶性肿瘤的10%~30%,与POMT在影像及病理上非常相似,两者的鉴别很困难。不同原发肿瘤的MOT有各自特征,如K r ukenberg瘤典型表现为双侧、实性、T2WI上非均质信号的肿块;结肠癌的MOT常为双侧、伴不同大小实性成分的囊性肿瘤;源自阑尾的MOT常为双侧卵巢黏液性肿瘤,伴腹膜假性黏液瘤。近年来功能成像如扩散加权成像(DWI)、灌注加权成像(PWI)及磁共振波谱(MRS)的发展和应用,使MRI在卵巢肿瘤的鉴别诊断、预后及疗效评价等方面发挥越来越重要的作用。
[Abstract]:MRI has important diagnostic value in the evaluation of benign and malignant ovarian tumors by virtue of multidirectional imaging and good tissue contrast. The specific MRI signs of differential diagnosis of primary ovarian malignant tumor (MRI) and metastatic tumor (mot) have not been reported. MOT accounts for 10% of all ovarian malignant tumors, which is very similar to POMT in imaging and pathology, so it is very difficult to differentiate between them. The MOT of different primary tumors has its own characteristics. For example, the typical features of K r ukenberg tumor are bilateral, heterogeneous mass on solid T _ 2WI; MOT of colon cancer is usually bilateral, with different size solid components of cystic tumor; MOT originating from appendix is usually bilateral ovarian mucinous tumor. In recent years, the development and application of functional imaging, such as diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and magnetic resonance spectroscopy (MRS), in the differential diagnosis of ovarian tumors. Prognosis and evaluation of curative effect play a more and more important role.
