摘要
目的评价18F-FDG符合线路显像在探查肿瘤原发灶中的临床应用价值。方法对临床确诊转移癌但原发灶不明确的患者14例进行18F-FDG符合线路显像,以18F-FDG浓聚程度作为异常判断标准探查可疑原发灶,并结合病理学、影像诊断方法及随访加以证实。结果双探头18F-FDG符合线路显像对原发灶的检出率为50%(7/14)。原发灶部位与正常组织的放射性比值(T/N)均在2.5~5.5之间。结论双探头18F-FDG符合线路显像是寻找不明原发灶转移癌的一种有用的方法。
Objective To evaluate the clinical application value of ^18F - FDG coincidence SPECT in detecting primary tumors. Methods ^18F- FDG coincidence SPECT was performed on 14 patients with unknown primary tumors, the degree of ^18F-FDG uptake on diseased region was regarded as abnormal criterion. Results The detection rate of ^18F-FDG coincidence SPECT for primary tumors was 50% （7/14）. The radioactivity ratio of primary tumors and normal tissue was between 2.5 -5.5. Conclusions ^18 F - FDG coincidence SPECT is an effective method for primary tumor detection.
