Various diagnostic imaging techniques such as sonography, computed tomography, scintigraphy, radiography, and magnetic resonance imaging (MRI) have made possible the noninvasive evaluation of skeletal muscle injury and disease. Although these different modalities have roles to play, MRI is especially sensitive in the diagnosis of muscle disorders and injury and has proved to be useful in determining the extent of disease, in directing interventions, and in monitoring the response to therapies. This article describes how magnetic resonance images are formed and how the signal intensities in T1- and T2-weighted images may be used for diagnosis of the above-mentioned conditions and injuries.
各种诊断成像技术，如超声、计算机断层扫描、闪烁扫描、放射摄影和磁共振成像（MRI），使得对骨骼肌损伤和疾病进行非侵入性评估成为可能。尽管这些不同的方式都有其作用，但 MRI 在肌肉疾病和损伤的诊断中特别敏感，并且已被证明在确定疾病程度、指导干预措施以及监测治疗反应方面有用。本文描述了磁共振图像是如何形成的，以及 T1 和 T2 加权图像中的信号强度如何用于诊断上述情况和损伤。
