There has been a rapid increase in the utilization of MRI in rectal cancer staging in the USA essentially replacing endorectal ultrasound and mimicking the trend in Europe seen in the 1990s and 2000s. Accompanying this trend, there is a demand, and recognized need, for greater precision and clarification of confusing, misunderstood and poorly understood concepts, facts, statements and nomenclature regarding rectal cancer and the use of pelvic MRI for diagnosis. As such, this Review, part evidence-based and part expert opinion, will attempt to elucidate and clarify several concepts the authors have encountered in 25 years of imaging rectal cancer, focusing on MRI.
在美国，MRI 在直肠癌分期中的应用迅速增加，基本上取代了腔内超声，并模仿了 20 世纪 90 年代和 21 世纪初在欧洲出现的趋势。伴随这一趋势，人们对直肠肿瘤和盆腔 MRI 诊断的使用的相关概念、事实、陈述和命名存在着更大的精确性和清晰度的需求，这些需求被认为是有必要的。因此，本综述部分基于循证医学，部分基于专家意见，将尝试阐明和澄清作者在 25 年的直肠癌成像中遇到的几个概念，重点是 MRI。
