摘　　要：目的研究MRI在腓肠肌损伤诊断价值和临床意义。材料与方法选取24例X线平片没有显示胫腓骨骨折患者的临床资料,患者MRI检查显示有腓肠肌损伤,MRI检查时间为患者伤后2周内,使用相控阵表面体线圈,使用常规T1WI和T2WI脂肪抑制序列,平行胫腓骨长轴的矢状面及冠状面进行扫描,辅垂直于骨骼长轴的横断面。结果 24例患者中Ⅰ度损伤9例,Ⅱ度损伤12例,Ⅲ度损伤3例,所有患者无胫腓骨骨折或骨挫伤。结论在腓肠肌损伤的检查中,MRI检查结果清晰、直观,准确率较高,临床可以作为诊断依据。Objective： To research the diagnostic value of the gastrocnemius muscle injury and clinical signiifcance of MRI.Materials and Methods：The clinical data of 24 patients with no fractures in the tibia and fibula showed on X-ray were selected, while MRI examination showed that there were injury in the calf. MR examination was performed with phased-array body coil surface, conventional T1WI and T2WI with fat suppression, the scan of the long axis parallel to the tibia and fibula in the sagittal and coronal and auxiliary cross section perpendicular to the long axis of the bone within two weeks after injury.Results：Nine cases of 24 patients were slightly injured （degreeⅠ）, 12 cases of them were moderate injured （degreeⅡ） and three of them were severely injured （degreeⅢ）. All patients did not have tibia and ifbula fractures or bone contusion.speciifcity 80.6%, this time accurate index was the highest and best diagnostic efifcacy.Conclusions： MRI ifndings in the gastrocnemius muscle damage examination are clear, intuitive and highly accurate so it can be used as clinical diagnosis.
