目的 探讨核素脑池动态显像在脑脊液鼻漏诊断和治疗中的临床意义。方法 回顾性分析了 15例脑脊鼻漏的临床资料 ,尤其是核素脑池动态扫描的结果。结果 15例病人中 14例核素脑池动态扫描有核素异常分布 ,且鼻漏出液放射性测定有核素显影 ,1例核素分布正常。 14例核素分布异常病人 ,13例手术证实漏口与核素扫描结果一致 ,1例保守治疗成功。 1例核素分布正常者 ,诊断假性脑脊液鼻漏 ,药物治疗而愈。结论 核素脑池动态显像作为一种简单创伤小的检查手段 ,对确定有无脑脊液鼻漏和确定具体漏口部位有重要作用
Objective To investigate the clinical significance of radionuclide brain pool dynamic imaging in the diagnosis and treatment of cerebrospinal fluid rhinorrhea. Methods The clinical data of 15 cases with cerebrospinal rhinorrhea were retrospectively analyzed, especially the results of dynamic scanning of nuclide brain pool. Results Of the 15 patients, 14 cases of radionuclide brain dynamic scanning had abnormal distribution of radionuclide, and the radioactive determination of nasal leakage fluid showed radionuclide imaging. One case had normal radionuclide distribution. Of the 14 patients with abnormal radionuclide distributions, thirteen surgeries confirmed that the leak was consistent with the results of the radionuclide scanning, and one of the conservative treatment was successful. One case of normal distribution of radionuclides, rhinorrhea diagnosis of false cerebrospinal fluid leakage, drug treatment and more. Conclusion The dynamic imaging of radionuclide brain pool is a simple means to check traumatic injury and plays an important role in determining whether there is cerebrospinal fluid rhinorrhea and identifying the specific leak site
