小腿肌肉、肌腱损伤多发生于下肢运动过度或运动不当。由于生活习惯的改变,小腿肌肉、肌腱损伤的发生率也在逐渐增加。不同的肌肉、肌腱损伤类型其治疗方案和效果存在较大差异,而不论何种损伤及早治疗至关重要~([1])。目前,核磁共振成像(magnetic resonance imaging,MRI)是肌肉、肌腱损伤的诊断和分类的金标准~([2])。然而MRI检测存在耗时长、费用高、机器维护成本高等缺陷。有研 Calf muscle, tendon injury occurred in the lower extremities or excessive exercise inappropriately. Due to changes in lifestyle, the incidence of calf muscle, tendon injury is also gradually increased. Different types of muscle and tendon injuries have significant differences in treatment options and effects, regardless of the type of injury and early treatment (1). Currently, magnetic resonance imaging (MRI) is the gold standard for the diagnosis and classification of muscle and tendon injuries. However MRI testing has the drawback of long time-consuming, high cost and high machine maintenance cost. With research
