目的探讨如何提高碘海醇CT脑池造影(CTC)检查的敏感性及特异性.方法回顾性分析20例脑脊液鼻漏患者的临床资料,观察活动性脑脊液鼻漏及不同蛛网膜下隙充盈时间对检查结果的影响.结果检查时存在活动性脑脊液鼻漏者19例,均通过CTC定位到漏口部位,其中18例患者接受手术治疗,术中证实术前漏口定位确切.1例患者检查时无活动性脑脊液鼻漏,CTC检查未发现漏口.对存在筛窦漏口的影像分析表明:检查时蛛网膜下隙充盈时间≥10 min患者9例,其中7例影像质量评价为清晰,蛛网膜下隙充盈时间＜ 10 min患者6例,仅1例影像质量评价为清晰,两者比较差异有统计学意义(P=0.0406).结论为提高碘海醇CTC检查阳性率,检查时要注意保持活动性脑脊液漏的体位,注药至扫描的间隔时间≥10 min者可获得较好的影像质量.

Objective To explore how to improve the sensitivity and specificity of CT cisternography (CTC) examination.Methods The clinical data of 20 cases of CTC in detecting cerebrospinal fluid rhinorrhea were analyzed,and the influence of continuous dripping of fluid and the filling time of subarachnoid space upon the image quality were observed.Results Nineteen cases of active cerebrospinal fluid rhinorrhea were found with CTC,and the fistula sites were determined by CTC.Eighteen cases received operation which confirmed the fistula sites.One case was found with no active fistula site.According to the image of ethmoid sinus leaks results,7 cases had better image quality in 9 cases whose subarachnoid space filling time was longer than or equal to 10 min.One case had better image quality in 6 cases whose subarachnoid space filling time was shorter than 10 min.There was significant difference (P =0.0406).Conclusion To raise the positive rate of CTC,the position of active fistula should be maintained and keep the time between the injection and scan longer than or equal to 10 min,which help to get better image quality.
