目的探讨胃癌术后~(18)氟-氟代脱氧葡萄糖(~(18)F-FDG)单光子发射计算机断层显像/电子计算机断层扫描(SPECT/CT)对胃癌术后复发与远处转移的诊断价值。方法回顾性分析50例胃癌患者的~(18)F-FDG SPECT/CT资料,比较同期传统检查技术结果,计算~(18)F-FDG SPECT/CT显像与传统检查技术评估胃癌治疗后复发与转移的灵敏度、特异度、准确度、阳性预测值(PPV)与阴性预测值(NPV)。结果 ~(18)F-FDG SPECT/CT显像对胃癌术后复发与转移评估的灵敏度、特异度、准确度、PPV及NPV分别为87.5%、96.2%、92.0%、95.5%和89.3%,传统检查技术分别为50.0%、96.2%、74.0%、92.3%和67.6%,灵敏度和准确度比较有统计学差异(P<0.05)。结论与传统检查技术比较,~(18)F-FDG SPECT/CT可以更准确地评估胃癌术后复发与远处转移。
Objective To investigate the effect of 18F-18F-FDG single-photon emission computed tomography / computed tomography (CT-SPECT) on postoperative recurrence and distant metastasis of gastric cancer The diagnostic value. Methods The data of ~ (18) F-FDG SPECT / CT in 50 patients with gastric cancer were analyzed retrospectively. The results of conventional examination were compared. The results of ~ (18) F-FDG SPECT / Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of metastasis were compared. Results The sensitivity, specificity, accuracy, PPV and NPV of ~ (18) F-FDG SPECT / CT imaging were 87.5%, 96.2%, 92.0%, 95.5% and 89.3% The traditional techniques were 50.0%, 96.2%, 74.0%, 92.3% and 67.6%, respectively. The sensitivity and accuracy were statistically significant (P <0.05). Conclusion Compared with the conventional technique, ~ (18) F-FDG SPECT / CT can evaluate the recurrence and distant metastasis of gastric cancer more accurately.
