Abstract
Osteoarthritis (OA) is a disabling chronic disease involving the gradual degradation of joint structures causing pain and dysfunction. Magnetic resonance imaging (MRI) has been widely used as a non-invasive tool for assessing OA-related changes. While anatomical MRI is limited to the morphological assessment of the joint structures, quantitative MRI (qMRI) allows for the measurement of biophysical properties of the tissues at the molecular level. Quantitative MRI techniques have been employed to characterize tissues' structural integrity, biochemical content, and mechanical properties. Their applications extend to studying degenerative alterations, early OA detection, and evaluating therapeutic intervention. This article is a review of qMRI techniques for musculoskeletal tissue evaluation, with a particular emphasis on articular cartilage. The goal is to describe the underlying mechanism and primary limitations of the qMRI parameters, their association with the tissue physiological properties and their potential in detecting tissue degeneration leading to the development of OA with a primary focus on basic and preclinical research studies. Additionally, the review highlights some clinical applications of qMRI, discussing the role of texture-based radiomics and machine learning in advancing OA research.
骨关节炎(OA)是一种致残性慢性疾病,涉及关节结构的逐渐退化,引起疼痛和功能障碍。磁共振成像(MRI)已被广泛用作评估 OA 相关变化的非侵入性工具。解剖核磁共振成像仅限于对关节结构进行形态学评估,而定量核磁共振成像(qMRI)可在分子水平上测量组织的生物物理特性。定量磁共振成像技术已被用于描述组织的结构完整性、生化含量和机械特性。其应用范围扩展到研究退行性改变、早期 OA 检测和评估治疗干预。本文综述了用于肌肉骨骼组织评估的 qMRI 技术,尤其侧重于关节软骨。其目的是描述 qMRI 参数的基本机制和主要局限性、它们与组织生理特性的关联以及它们在检测导致 OA 发生的组织退化方面的潜力,主要侧重于基础研究和临床前研究。此外,该综述还强调了 qMRI 的一些临床应用,讨论了基于纹理的放射组学和机器学习在推进 OA 研究中的作用。
