Healing of a partially ruptured gastrocnemius muscle was studied in rats with sonographical and histological techniques. Ultrasonography was performed 1-21 days after injury using a 7.5-MHz linear scanner. Following ultrasonography, the injured muscles were examined histologically. The injured area and development of hematoma were visualized during the first 5 days after trauma with ultrasonographical and histological observations. Later, disorganization of regenerating muscle fibers appeared sonographically more clearly than the scar tissue area demonstrated histologically. The present study points out the accuracy of ultrasonography in the examination of a muscle trauma, especially during the early phases of healing.
利用超声和组织学技术研究了大鼠腓肠肌部分断裂后的愈合情况。损伤后1至21天,使用7.5兆赫线性扫描仪进行超声检查。超声检查后,对受伤肌肉进行组织学检查。创伤后的前5天,通过超声和组织学观察可看到损伤区域和血肿的形成。之后,超声显示再生肌纤维的紊乱比组织学显示的瘢痕组织区域更清晰。本研究指出了超声检查在肌肉创伤检查中的准确性,尤其是在愈合早期。
