1、110例脊柱外伤的CT和MRI影像诊断对比分析【摘要】H的探讨脊柱外伤的CT和MRI影像的表现以及特点,并研究两者在脊柱外伤诊断屮的价值与临床意义。方法收集脊柱外伤患者的CT、MRI资料110例,并对其进行分析。对比分析两者对损伤脊林的附件骨折、椎体骨折,碎骨片位移、脊髓损伤、脊林1川度改变、椎管容积改变、韧帯损伤、软组织损伤、神经根损伤、椎间盘损伤的诊断效果。结果(1)CT対发现单纯无变形椎体裂纹骨折与特殊部位的骨折效果明显,对显示椎体、椎弓骨折线和骨折片的移位优于MR1;(2)MRI则对显示脊髓损伤(P<0.0
2、5)、韧带损伤(P<0.01)、神经根损伤(P<0.05)、软纟R织损伤(P<0.05)比CT更敏感、更清晰,与CT比较显示损伤范围更大、更明确。结论CT、MRI对显示脊柱外伤都有各自的优势和劣势,但MRI对脊柱外伤空间定位比较准确,并可检查出外伤导致的脊髄病变和损伤,因此,联合两种方法能够冇效的避免假阴性和假阳性的出现。【关键词】脊柱外伤;CT;MR1;脊髓损伤ComparativestudyonthediagnoseofCTandMRIin110caseswithspinaltraumaHUANGJian-fe
