Radiomics is a novel image analysis technique, whereby voxel-level information is extracted from digital images and used to derive multiple numerical quantifiers of shape and tissue character. Cardiac magnetic resonance (CMR) is the reference imaging modality for assessment of cardiac structure and function. Conventional analysis of CMR scans is mostly reliant on qualitative image analysis and basic geometric quantifiers. Small proof-of-concept studies have demonstrated the feasibility and superior diagnostic accuracy of CMR radiomics analysis over conventional reporting. CMR radiomics has the potential to transform our approach to defining image phenotypes and, through this, improve diagnostic accuracy, treatment selection, and prognostication. The purpose of this article is to provide an overview of radiomics concepts for clinicians, with particular consideration of application to CMR. We will also review existing literature on CMR radiomics, discuss challenges, and consider directions for future work.

心脏磁共振放射学：基本原理和临床观点

Radiomics是一种新颖的图像分析技术，可从数字图像中提取体素级信息，并将其用于导出形状和组织特征的多个数字量词。心脏磁共振（CMR）是评估心脏结构和功能的参考影像学方法。CMR扫描的常规分析主要依赖于定性图像分析和基本几何量词。小型概念验证研究表明，与常规报告相比，CMR放射组学分析具有可行性和优越的诊断准确性。CMR放射学有可能改变我们定义图像表型的方法，并由此提高诊断准确性，治疗选择和预后。本文的目的是为临床医生提供放射学概念的概述，特别考虑适用于CMR。我们还将审查有关CMR放射学的现有文献，讨论挑战，并考虑未来工作的方向。
