Abstract
Modern rectal cancer management is dependent on preoperative staging, and radiological assessment is a crucial part of this process. Imaging must provide sufficient information to guide preoperative decision-making that is reliable and reproducible. Different methods have been used for local staging; however, magnetic resonance imaging (MRI) has shown to be the most reliable tool for this purpose. MRI offers prognostic information about the patients and guides the decision between neoadjuvant treatment and total mesorectal excision alone. Also, not only the initial staging but also restaging by MRI can provide significant information regarding tumor response that is essential when considering alternative approaches.
摘要
现代直肠癌的治疗依赖于术前分期，而影像学评估是这一过程的关键部分。成像必须提供足够的信息，以指导可靠且可重复的术前决策。已经使用了不同的方法进行局部分期；然而，磁共振成像（MRI）已被证明是用于此目的最可靠的工具。MRI可提供有关患者的预后信息，并指导新辅助治疗与单纯全直肠系膜切除术之间的决策。此外，不仅初始分期，而且通过MRI进行的再分期都可以提供有关肿瘤反应的重要信息，这在考虑替代方法时至关重要。
