单指数、双指数及拉伸指数模型扩散加权成像在卵巢肿瘤及子宫内膜癌中的应用进展

Application of diffusion weighted imaging with monoexponential,biexponential and tensile exponential models in ovarian tumors and endometrial cancer

卵巢肿瘤和子宫内膜癌严重威胁女性健康甚至危及生命,随着医疗技术水平和健康意识的不断提高,卵巢肿瘤和子宫内膜癌的发病率亦逐年增加,早发现、早诊断、早治疗已成为规范应对两者的原则。超声检查和诊刮术分别为卵巢肿瘤和子宫内膜癌的主要筛查方式,但误诊率、漏诊率较高。磁共振扩散加权成像技术及其衍生模型以兼具高分辨率、无创性、多方位成像的优势越来越多的应用到卵巢肿瘤和子宫内膜癌的诊断中。本篇文章对不同弥散模型在卵巢肿瘤及子宫内膜癌中的应用进展予以综述,以期获得不同弥散模型对卵巢及子宫内膜肿瘤的诊断价值。

Ovarian tumors and endometrial cancer are seriously threaten women's health and even life-threatening.With the continuous improvement of medical technology and health awareness,the incidence of ovarian tumors and endometrial cancer are also increasing.Early detection,early diagnosis and early treatment have become the principles to standardize the response to both.Ultrasonography and curettage are the main screening methods for ovarian tumors and endometrial cancer,respectively.The rate of misdiagnosis and missed diagnosis are high.Magnetic resonance diffusion-weighted imaging and its derivative techniques are increasingly used in the diagnosis of ovarian tumors and endometrial cancer because of their advantages of both high-resolution,seminal,and multi-directional imaging.This article reviews the application of different diffusion models in ovarian tumors and endometrial cancer,in order to obtain the diagnostic value of different diffusion models for ovarian and endometrial tumors.
