摘要
目的探析CT和MRI方法诊断极外侧型腰椎间盘突出症(FLLDH)的特点和价值。方法2008年6月至2012年12月湖北医药学院附属东风医院选取经手术证实确诊为FLLDH的患者30例(混合型、内侧型和外侧型分别为12例、6例和12例),均行CT及MRI两种检查方法,对比两种诊断方式的诊断率和诊断表现。结果经过观察,CT和MRI对于FLLDH的总体诊断率对比无统计学意义(P>0.05),两种诊断方式显示L4,L5的病变均为66.7%。CT显示为各种形态的软组织密度影,MRI显示的病变特征为髓核信号。两种诊断方式的影像学征象对比均无统计学意义(P>0.05)。结论 CT和MRI对FLLHD的诊断率均较高,两种方法都具有各自的显著诊断特点,对临床医师手术入路具有指导价值。
Objective To analyze the characteristics and value of CT and MRI method for diagnosis of FLLDH. Methods During Jun. 2008 and Dec. 2012,30 patients with confirmed FLLDH by surgery（ 12 cases, 6 cases and 12 cases of hybrid,medial and lateral respectively）from Dongfeng Hospital of Hubei Medical Col- lege were selected, and given CT and MRI inspections, and diagnosis rate and performanceof the two methods were compared. Results Tile overall CT and MR/ diagnostic rate had no significant difference （P 〉 O. 05 ）, L4, L5 lesions were 66.7 % for both diagnosis methods. CT showed various soft tissue density shadow and MRI lesion characteristics was nucleus pulposus signal. Two diagnostic methods＇ imaging findings had no statistically significant difference （P 〉 0.05 ）. Conclusion The diagnostic rate of CT and MRI for FLLHD are both high, each with own significant diagnostic characteristics and guidance value for the surgical approach.
