| 摘 要： | 目的评价1.5T磁共振STIR序列对外伤性视神经损伤诊断的应用价值。方法 2002年3月至2011年12月对69例外伤性视神经损伤患者行1.5T磁共振检查(MRI),磁共振检查序列包括快速自旋回波序列(FSE)T1WI、快速自旋回波序列(FSE)T2WI、脂肪抑制序列短T1反转恢复成像(Short T1 Inversion-Recovery,STIR)等,回顾性分析外伤性视神经损伤的MRI表现。结果 MRI检查在常规(FSE)T1WI序列中显示病灶31例(44.9%),(FSE)T2WI序列中能显示56例(81.2%)外伤性视神经损伤病灶,STIR序列能检出病灶69例(100.0%),病变以STIR序列上表现最明显。结论 MRI能有效显示外伤性视神经损伤的病变部位及范围,其STIR序列可以准确诊断外伤性视神经损伤。 |

| Abstract: | Objective To evaluate the value of MRI with STIR in diagnosing optic nerve injury.Methods 69 patients of optic nerve injury,who received magnetic resonance imaging examination including(FSE)T1WI,(FSE)T2WI,short T1 inversion-recovery(STIR),were retrospective analyzed from March 2002 to November 2011.Results MRI showed 31(44.9%) foci with optic nerve injury by(FSE)T1WI sequence,56(81.2%) by(FSE)T2WI sequence and 69(100.0%) by STIR sequence.Conclusions MRI can effectively reveal the location and extent of optic nerve injury.And MRI with STIR is a preferred and safe diagnosis method. |
