【Abstract】 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.更多还原
