子宫内膜癌(endometrial carcinoma,EC)是女性生殖道常见的恶性肿瘤,近年来发病率逐年上升.淋巴脉管间隙浸润(lymphvascular space invasion,LVSI)被认为是早期EC患者发生盆腔淋巴结转移的独立危险因素,严重影响患者预后.术前对于LVSI进行准确评估有助于指导个体化手术方式的选择.常规MRI仅能通过形态学对LVSI进行评估,MRI功能序列可以通过定量参数评估LVSI状态.本文介绍了多模态MRI在LVSI评估中展现出的临床价值,旨在通过查阅分析近年来国内外相关文献,对多模态MRI评估LVSI的研究进行综述,为今后通过多模态MRI评估局灶性或弥漫性LVSI提供客观的影像学依据.
Advances in MRI studies of lymphvascular space invasion in endometrial carcinoma
Endometrial carcinoma (EC) is a common malignant tumor of female reproductive tract,the incidence of EC is increasing year by year in recent years. Lymphvascular space invasion (LVSI) is considered to be an independent risk factor for pelvic lymph node metastasis in early EC patients,which seriously affects the prognosis of patients. The accurate assessment of LVSI before surgery is helpful to guide the selection of individualized surgical methods. Conventional MRI is limited to evaluating LVSI based on morphology,whereas MRI functional sequences can assess LVSI status using quantitative parameters. This paper introduces the clinical value of MRI sequences in the diagnosis and evaluation of LVSI in EC,aiming to conduct a review by analyzing recent domestic and international literature,summarize LVSI evaluation by multimodal MRI in EC. To provide an objective imaging basis for evaluating LVSI by multimodal MRI.
