Abstract

Magnetic resonance imaging (MRI) has established itself as the primary method for local staging in patients with rectal cancer. This is due to several factors, most importantly because of the ability to assess the status of circumferential resection margin. There are several newer developments being introduced continuously, such as diffusion-weighted imaging and imaging with 3 T. Assessment of loco-regional lymph nodes has also been investigated extensively using different approaches, but more work needs to be done. Finally, evaluation of tumours during or after preoperative treatment is becoming an everyday reality. All these new aspects prompt a review of the most recent advances and opinions. In this review, a comprehensive overview of the current status of MRI in the loco-regional assessment and management of rectal cancer is presented. The findings on MRI and their accuracy are reviewed based on the most up-to-date evidence. Optimisation of MRI acquisition and relevant regional anatomy are also presented, based on published literature and our own experience.

摘要

磁共振成像（MRI）已成为直肠癌患者局部分期的主要方法。这归因于几个因素，最重要的是其能够评估环周切缘的状态。不断有一些新进展被引入，如扩散加权成像和3T成像。使用不同方法对局部区域淋巴结的评估也已得到广泛研究，但仍需开展更多工作。最后，术前治疗期间或之后对肿瘤的评估正成为日常现实。所有这些新情况促使我们对最新进展和观点进行综述。在本综述中，对MRI在直肠癌局部区域评估和管理中的当前状况进行了全面概述。基于最新证据对MRI的发现及其准确性进行了综述。还根据已发表的文献和我们自己的经验介绍了MRI采集的优化及相关区域解剖结构。
