受伤机制在头部外伤急诊CT诊断中的重要意义

Significances of traumatic mechanism in CT fingding of acute head injuries

目的探讨受伤机制在头部外伤急诊CT诊断中的重要意义。方法对笔者所在医院经临床、手术证实有明确诊断结果的头部外伤CT阳性病例1000例进行双盲阅片,试验组(审核组)通过询问受伤过程、分析受伤机制和分析CT图像得出诊断;对照组(报告组)忽略受伤过程、忽略受伤机制,只通过观察CT图像得出诊断。统计两组正确诊断率。结果试验组(审核组)正确诊断987例(98.70%),对照组(报告组)正确诊断761例(76.10%),试验组的正确诊断率明显高于对照组。结论受伤机制在头部外伤CT诊断中具有十分重要的意义。

Objective To discuss signifieances of traumatic mechanism in CT fingding of acute bead injuries. Methods 1000 CT cases of acute head injuries were double - blind diagnosed, all cases were ultimate diagnosed by clinical diagnosis or/and postoperative diagnosis. Experimental group was diagnosed by traumatic procedure, traumatic mechanism and CT images. Control group was diagnosed by CT images only, traumatic procedure and mechanism neglected. The correct diagnostic rate was calculated separately. Results 987（98.70% ） cases were correct diagnosed in experimental group,761 （76. 10% ） cases were correct diagnosed in control group. The correct diagnostic rate of experimental group was supperior to control group. Conclusion Traumatic mechanism has high clinical significance in CT fingding of acute head injuries.
