【摘要】 目的探讨横纹肌溶解症(rhabdomyolysis,RML)的MRI特点,以及MRI对该病的诊断与早期诊断价值。资料与方法搜集12例经临床和MRI证实为RML患者的资料,对其临床特点和MRI表现进行回顾性分析。结果发生在臀中肌者5例,臀大肌者3例,四肢肌肉者4例。5例常规T1WI、T2WI均表现为等信号,其余7例T2WI为稍高信号,T1WI为稍低或等信号。所有病例T2WI脂肪抑制序列均呈高信号;增强后病变区有不同程度片、絮状强化;5例磁共振血管成像示病变区供血动脉走行自然。结论MRI可以清楚显示RML的MR信号改变、部位及累及范围,具有早期诊断价值,对于早期治疗及预防并发症的发生具有指导性意义。更多还原

【Abstract】 Objective To discuss the value of MRI in diagnosis of the rhabdomyolysis.Materials and Methods The MRI findings and clinic characteristic of 12 cases with rhabdomyolysis confirmed by MRI and clinic were analyzed retrospectively.Results The location number of the cases was in mesoglutaeus,in ectogluteus,in extremities muscle was 5,3,4 respectively.7 cases were depicted as slight hyperintensity signal on T2WI and T1WI slightly hypointensity or isointensity signal on T1WI.All the cases had hyperintensity signal on T2WI fat-suppressed sequence.Different level lamellar or patch enhancement was showed on enhanced MR.Course of feeding artery in lesion was nature in 5 cases.Conclusion The location and range of rhabdomyolysis are depicted clearly by MRI,MR has some significance on guiding the early diagnosis,early treatment and precaution complication of rhabdomyolysis.更多还原
