急性肌肉拉伤的MRI应用进展

急性肌肉拉伤是一种急性间接肌肉损伤,常见于日常生活和运动中。仅根据临床症状和体格检查难以准确诊断。常规MRI软组织分辨率高,是急性肌肉拉伤诊断和预后评估的重要手段。近年发展的肌肉MR弹性成像、T2弛豫时间图、磁共振扩散加权成像、扩散张量成像和磁共振波谱具有从微观结构、病理和生理层面为急性肌肉拉伤的诊断提供定量、客观依据的潜力。作者对应用于急性肌肉拉伤的各项MRI技术进行综述。

Progress in magnetic resonance imaging application of acute muscle strain

Acute muscle strain is defined as an acute indirect muscle injury and is common in daily life.In clinical practice,it is difficult to accurately diagnose based on symptoms and physical examination.Conventional magnetic resonance imaging(MRI)has high soft tissue resolution and is critical for the diagnosis and prognosis evaluation of acute muscle strain.Novel MRI techniques developed in recent years,including muscle MR elastography(MRE),T2 mapping,magnetic resonance diffusion weighted imaging(DWI),diffusion tensor imaging(DTI)and magnetic resonance spectroscopy(MRS),make it possible to observe the micro structure of strained muscle and provide quantitative and objective evidence for the diagnosis of acute muscle strain.This article reviews the various MRI techniques for acute muscle strain.
