SPECT与X线联合诊断鼻咽癌骨转移的临床价值

目的 探讨SPECT联合X线诊断鼻咽癌骨转移的临床应用价值。方法 选择60例鼻咽癌初诊患者行SPECT全身骨核素显像和X线检查。结果 60例鼻咽癌经SPECT和X线共同诊断为骨转移53．3％(32／60)，SPECT显像阳性率为78．3％(47／60)，假阳性率为16．7％；X线诊断阳性率为45％(27／60)，骨转移的部位以脊柱多见，其余依次为胸部、骨盆、肢体和颅骨。结论 SPECT全身骨显像与X线联合检查对于临床诊断分期及治疗有重要意义。可作为鼻咽癌治疗前的常规检查。

Clinical Diagnostic Value of the Combination of SPECT and X-ray on Skeletal Metastases of Nasopharyngeal Carcinoma

Objective To investigate the clinical value of the combination of SPECT and X-ray on skeletal metastases of nasohparyngeal carcinoma (NPC). Methods 60 patients with nasohparyngeal carcinoma who had not got treatment were underwent SPECT imaging and X-ray scan. Results Among the 60 cases, 53.3% of patients ( 32/60) were diagnosed as having skeletal metastases by the combination of SPECT and X-ray. 78.3% (47/60) of patients were identified to be anomaly by SPECT imaging. The false positive rate of SPECT was 16.7%. The positive rate of X-ray was 45%. The site of bone metastatic lesions was more common in spine,and the following sites were thorax, pelvis, limbs and skull. Conclusions Both SPECT imaging and X-ray scan should performed before treatment on patients with nasohparyngeal carcinoma. They were very important for evaluation of clinical stage and therapy.
