Objective The purpose of this study was to evaluate the clinical value of the 99Tcm-DTPA cerebrospinal fluid (CSF) Hawkeye SPECT fusion imaging for diagnosing and localizing CSF rhinorrhea (CSFR). Methods Thirty-three patients with suspected CSFR were included in this study. All cases un-derwent planar and SPECT and CT imaging at 120 and 180 min, respectively, after 99Tcm-DTPA injection via lumbar puncture before surgery treatment. The location and path of CSF leakage were diagnosed on pla-nar and SPECT fusion imaging. SAS 6.12 software was used to analyze both sets of imaging data, and the χ2 test was used to compare the results from planar imaging with those of SPECT fusion imaging. Results In 33 patients with CSFR, 31 abnormally concentrated radionuclide activity and location of leakage were foun-ded on SPECT fusion imaging, whereas 30 of such abnormalities were detected by planar imaging. All CSFR cases were confirmed by surgery afterwards. The sensitivity and accuracy for diagnosing and localizing CSFR were 93.9% (31/33), 90.9% (30/33) in SPECT fusion imaging and 93.5% (29/31), 78.3% (18/23) in planar imaging. Conclusion 99Tcm-DTPA CSF Hawkeye SPECT fusion imaging is an efficient, simple and accurate method for diagnosing and localizing CSF leakage.  相似文献
