摘要

鉴定淋巴结是否存在转移目前仍是直肠癌诊疗的一大挑战，临床上通常以淋巴结形态学标准来判断淋巴结是否存在转移，但这种方法尚不准确。磁共振成像（magnetic resonance imaging，MRI）是目前预测直肠癌淋巴结转移的主要影像学检查方法，而常规MRI、功能MRI及影像组学的定量分析可以提供更多淋巴结形态学和本质信息，有望提高判断有无淋巴结转移的准确度，有助于更好地制订临床诊疗方案，为实现影像学研究的临床转化奠定基础。本文对常规MRI、功能MRI及影像组学的定量参数评估直肠癌淋巴结转移的主要研究进展进行综述。

Abstract

Identification of metastasis of lymph nodes is still a major challenge in the diagnosis and treatment of rectal cancer. Clinically

lymph node morphology is usually used to determine whether there is metastasis in lymph node

but this method is not accurate yet. At present

magnetic resonance imaging (MRI) is the main imaging method to predict lymph node metastasis of rectal cancer

and the quantitative analysis of routine MRI

functional MRI and radiomics can provide more morphological and essential information of lymph nodes

which is expected to improve the accuracy of judging whether there is metastasis of lymph nodes

contribute to better clinical diagnosis and treatment plan

and lay a foundation for the clinical transformation of image research. In this paper

the main progress of MRI in the evaluation of lymph node metastasis of rectal cancer were reviewed.
