【摘要】：随着影像技术的发展,高分辨率磁共振成像(HRMRI)以其高软组织分辨率、高空间分辨率的特点逐渐受到人们的重视。HRMRI现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局部分期,同时准确评估相关不良预后因素,如环周切缘、壁外脉管侵犯、肿瘤位置等,有助于选择合适的局部进展期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,从而提高患者的预后及生命质量。HRMRI还可以初步评估新辅助治疗后的疗效,为是否进一步行术前优化治疗提供参考依据。
[Abstract]:With the development of image technology, high resolution magnetic resonance imaging (HRMRI) has its high soft tissue resolution. The characteristics of high spatial resolution have been paid more and more attention. HRMRI has become an indispensable imaging method for multi-disciplinary team to evaluate local advanced rectal cancer. HRMRI can perform accurate preoperative local staging of the tumor. At the same time, accurate evaluation of the associated adverse prognostic factors, such as circumferential margin, extramural vascular invasion, tumor location, etc., is helpful to select appropriate neoadjuvant therapy for locally advanced rectal cancer patients. In order to improve the prognosis and quality of life, HRMRI can be used to evaluate the curative effect of neoadjuvant therapy, and to provide reference for further optimizing treatment before operation.
