基于MR影像组学列线图在直肠癌壁外血管侵犯中的研究进展

Research progress of nomogram based on MR-radiomics in extramural vascular invasion of rectal cancer

近年来,列线图在直肠癌中的研究越来越广泛,已成功用于直肠癌的诊断、治疗和预后,一些相关的影像组学研究也引入了列线图模型,且数量逐年增多,尤其是基于MR影像组学的列线图模型。笔者通过文献回顾发现,大多数基于MR影像组学的列线图模型对直肠癌壁外血管侵犯的预测效能优于单一的影像组学,但在研究方法与结果上存在差异。本文归纳总结了几种主要的研究方法,综合论述了基于MR影像组学的列线图在直肠癌壁外血管侵犯中的研究现状及前景。

In recent years,nomograms have been widely used in the diagnosis,treatment,and prognosis of rectal cancer.Some related radiomics studies have also introduced nomogram models,and the number is increasing year by year,especially the nomogram models based on magnetic resonance radiomics.Through a literature review,the author found that most of the nomogram models based on MR Radiomics were better than single radiomics in predicting extramural vascular invasion of rectal cancer,but there were differences in research methods and results.This article summarized several main research methods and comprehensively discussed the research status and prospects of the nomogram based on MR radiomics in the diagnosis of extramural vascular invasion of rectal cancer.
