高分辨率磁共振在局部进展期直肠癌中的应用

Application of high resolution magnetic resonance imaging in locally advanced rectal cancer

高分辨率磁共振（HRMRI）已成为多学科团队评估局部进展期直肠癌不可或缺的影像学方法.HRMRI可以对肿瘤进行准确的术前分期,同时准确评估相关不良预后因素,如环周切缘、脉管浸润等.HRMRI可以选择合适的直肠癌患者行新辅助治疗,对仅需单纯手术的患者可以避免过度治疗,从而提高局部进展期直肠癌患者的预后及生命质量.

High resolution magnetic resonance imaging （HRMRI） has become an indispensable tool for multidisciplinary teams addressing locally advanced rectal cancer.Preoperative HRMRI is accurate in predicting tumor stage and poor prognostic features,such as circumferential resection margin and extramural venous invasion,et al.HRMRI is a precise diagnostic tool to select who may benefit from neo-adjuvant therapy and to avoid over treatment in those patients who can proceed directly to surgery,thus achieving better prognosis and quality of life for patients with locally advanced rectal cancer.
