【摘要】 目的探讨椎管内血肿的CT及MRI表现特点,提高椎管内血肿CT及MRI表现的认识。方法回顾分析18例经手术及临床治疗随访复查证实的椎管内血肿的CT及MRI表现。18例患者均常规CT、MR平扫,其中2例MR增强扫描。使用GE公司Lightspeed 16CT扫描仪,及Phillip 1.5TAcheive超导MR扫描仪,2例MR增强扫描采用钆喷酸葡甲胺(Gd-DTPA)对比剂经静脉团注,注射剂0.1mmol/kg。结果颈胸段3例,胸段5例,胸腰段6例,腰段4例;位于脊髓背侧方14例,脊髓两侧2例、腹侧2例。硬膜外血肿11例,硬膜下血肿6例,硬膜外血肿并蛛网膜下腔内积血1例。CT表现为高密度或等密度,MRI分别呈长T1长T2信号、长T1短T2信号、等T1短T2信号及短T1长T2信号,其中2例MR增强扫描,1例边缘强化,1例未见强化。结论椎管内血肿的CT、MRI表现具有一定的特征性,对其定性定位诊断及鉴别诊断有着重要的价值。更多还原

【Abstract】 Objective To investigate the CT and MRI Imaging characteristics of hematoma in spinal canal so as to improving the understanding of this disease.Methods 18patients with spinal canal hematoma of confirmed by surgery and clinical follow-up were retrospective reviewed.18patients were subjected to CT and MRI scan,of which 2to the enhanced MR scanning.GE Lightspeed 16CT scanner and Phillip 1.5Tacheive superconducting MR scanner were used.As for the 2 cases underwent the enhanced MR scanning,gadolinium spray acid meglumine(Gd-DTPA)contrast agent was used by intravenous injection,with injection dose of 0.1mmol/kg.Results 3cases were found in neck thoracic segment,5cases in thoracic segments,6cases in chest and waist segment,and 4cases in waist section.14cases were located in the spinal cord dorsal side,2cases on both sides of the spinal cord,and 2cases in ventral side.There were 11cases of epidural hematoma,6cases of a subdural hematoma,and 1case of epidural hematoma and subarachnoid hemorrhage.CT performance appeared high density or equal density.MRI manifestations included a long T1/long T2signal,long T1/short T2signal, equal T1/short T2signal,and short T1/long T2signal.With respect to the 2cases to enhanced MR scan,one was shown edge reinforcement and the other was not seen reinforcement.Conclusion The CT and MRI features of spinal canal hematoma have certain characteristics and the qualitative positioning diagnosis and differential diagnosis have important values.更多还原
