摘要/Abstract

摘要：

侧方引流为中下段直肠重要引流途径。东西方学者对于侧方淋巴结转移治疗策略尚存争议，术前难以通过病理检查诊断侧方淋巴结转移。MRI是诊断直肠癌侧方淋巴结转移的主要方法，新辅助治疗前后患者诊断标准略有不同，CT、PET/CT和影像组学等方式在诊断侧方淋巴结转移也具有一定优势，必要时多种方法联用可为侧方淋巴结转移诊断提供帮助。

Abstract:

Lateral drainage is an important way for the middle and lower rectum. There are still disputes between Eastern and Western scholars regarding the treatment strategy of lateral lymph node metastasis. It is difficult to diagnose lateral lymph node metastasis by pathologic examination before surgery. MRI is the main method for diagnosis of lateral lymph node metastasis in rectal cancer. The diagnostic criteria for patients before and after neoadjuvant treatment are slightly different. CT， PET/CT and radiomics also have certain advantages in the diagnosis of lateral lymph node metastasis. If necessary， the combination of multiple methods can help in the diagnosis of lateral lymph node metastasis.
