目的 :研究18氟 氟化脱氧葡萄糖 ( 18F FDG)在下咽部肿瘤诊断中的作用。方法 :2 0例下咽部肿瘤患者均接受18F FDG检查及CT、全组内镜 (食管、咽喉、气管镜 )检查。结果 :2 0例下咽部肿瘤患者18F FDG检查结果显示 :2例阴性 ;18例肿瘤原发部位有同位素浓集 ,其中 5例伴异位同位素浓集。对此 5例患者进一步临床、病理检查证实 :1例食管部占位 ,2例肺部病变 ,2例为良性改变。18F FDG检查结果显示的病变范围与CT、内镜检查相符。结论 :18F FDG检查可以提高下咽部肿瘤、尤其是隐匿的并发肿瘤诊断的准确性 ,明确病变范围 ,为临床治疗提供依据 ;同时又是一个简单、易行的下咽部肿瘤的随访检查手段。
Objective: To investigate the role of 18F FDG in the diagnosis of hypopharyngeal tumors. Methods: Twenty cases of hypopharyngeal tumors were examined by 18F FDG and CT. All patients underwent endoscopy (esophagus, throat, bronchoscopy). Results: The results of 18F FDG examination in 20 patients with hypopharyngeal tumors showed that 2 cases were negative. In 18 cases, the primary site of tumor was isotopic concentration, of which 5 cases were accompanied by ectopic isotope concentration. In this 5 patients further clinical and pathological examination confirmed: 1 cases of esophageal space occupying, 2 cases of lung disease, 2 cases of benign changes. 18F FDG examination showed lesions and CT, endoscopy consistent. Conclusion: The 18F FDG examination can improve the accuracy of diagnosis of hypopharyngeal tumors, especially occult tumors, clarify the extent of lesions and provide the basis for clinical treatment. At the same time, it is a simple and easy follow-up examination of hypopharyngeal tumors .
