【摘要】 目的 :探讨核素脑池显像诊断和定位脑脊液鼻漏的临床价值及提高定性和定位诊断的有关技术环节。方法 :采用99Tcm DTPA法对 1 2例脑脊液鼻漏患者进行核素脑池显像。结果 :1 1例颅底至鼻部有异常放射性浓聚影 ,其中 9例手术证实漏口与核素脑池显像定位诊断完全一致 ,其诊断灵敏度和定位准确率分别为 91 .7% (1 1 / 1 2 )和 81 .8% (9/ 1 1 )。结论 :99Tcm DTPA脑池显像作为灵敏、简便和定位准确的检查手段 ,可用于诊断和定位脑脊液鼻漏。提高定性和定位诊断的技术环节包括 :显像体位、图像标志、显像时机、促使脑脊液鼻漏和鼻道棉拭放射性测定更多还原

【Abstract】 Objective:To detect the clinical value of radionuclide cisternography for diagnosing and localizing cerebrospinal fluid rhinorrhea,and discuss the relative technical problems.Methods: 99 Tc m DTPA imaging was performed in 12 patients with cerebrospinal fluid rhinorrhea.Results:Eleven patients had positive imaging,of whom 9 showed correct situation of leakage that was confirmed by afterward surgery.The sensitivity and localizative accuracy were 91.7%(11/12) and 81.8%(9/11),respectively.Conclusion:The results suggested 99 Tc m DTPA cisternography is an efficient,simple and accurate method for diagnosis and localization of cerebrospinal rhinorrhea.The technical problems promoted diagnosis and localization include imaging position,marking,timing,promoting cerebrospinal fluid leaks and determining cotton’s radiocounting in the nasal cavity.更多还原
