摘要
目的探讨Hawkeye SPECT仪融合图像对隐匿性脑脊液鼻漏诊断和定位的临床价值及检查过程中的一些注意事项。方法选择30例确诊脑脊液鼻漏的患者,术前腰椎穿刺注射99mTc-DTPA后3h行SPECT/CT同机脑脊液断层显像,扫描结束后,进行图像处理及图像融合,通过图像分析确定脑脊液鼻漏的位置,进行定位诊断。结果 30例患者中,28例颅底至鼻部有异常放射性浓聚影,其中24例与手术证实漏口完全一致,其诊断灵敏度和定位准确性分别为93.3%(28/30)、85.7%(24/28)。结论 SPECT/CT同机脑脊液断层显像作为灵敏、简便和定位准确的检查手段,可用于隐匿性脑脊液鼻漏的定位诊断。
Objective The purpose of this study is to evaluate the clinical value of Hawkeye SPECT/CT fusion imaging for diagnosing and locating occult cerebrospinal fluid rhinorrhea and announcements.Methods Thirty patients with occult CSFR were included in this study.Al 1 cases underwent SPECT/CT imaging 180 minutes after lumbar puncture injection of 99mTc-DTPA before surgery treatment.The location and path of CSF leakage were diagnosed on SPECT/CT fusion imaging.Results 28 out of the 30 patients with CSFR had abnormally concentrated radionuclide activity from base of skull to nasal part on SPECT/CT fusion imaging.24 of such abnormalities were confirmed by surgery afterwards.The sensitivity and accuracy for diagnosing and locating CSFR were 93.3% （28/30）and 85.7% （24/28）in SPECT/CT fusion imaging.Conclusion SPECT/CT fusion imaging is an efficient, simple and accurate method for diagnosing and locating cerebrospinal fluid rhinorrhea.
