AIM
To evaluate the value of magnetic resonance imaging-detected extramural vascular invasion (MR-EMVI) in predicting regional lymph node metastasis (RLNM) in patients with rectal cancer.
METHODS
A total of 183 patients were included. A set of clinical and imaging factors including MR-EMVI were evaluated using univariate and multivariate analyses to determine the risk factors for RLNM.
RESULTS
Among the clinical and imaging factors evaluated, MR-EMVI, pathologic EMVI, nodal size, and diffusion-weighted imaging-detected positive nodes were independent predictors of RLNM.
CONCLUSIONS
MR-EMVI may be an independent predictor of RLNM in patients with rectal cancer.
目的
评估磁共振成像检测到的壁外血管侵犯（MR-EMVI）在预测直肠癌患者区域淋巴结转移（RLNM）中的价值。
方法
共纳入183例患者。使用单因素和多因素分析评估包括MR-EMVI在内的一系列临床和影像因素，以确定RLNM的危险因素。
结果
在评估的临床和影像因素中，MR-EMVI、病理EMVI、淋巴结大小和扩散加权成像检测到的阳性淋巴结是RLNM的独立预测因素。
结论
MR-EMVI可能是直肠癌患者RLNM的独立预测因素。
