目的 本研究旨在探讨18F-FDG PET/CT显像在淋巴瘤疗效评价中的临床 应用价值。方法 收集65例淋巴瘤患者的 临床资料，比较分析患者治疗后经18FFDG PET/CT显像检查的结果。结果 化疗 后患者的病灶最大标准吸收值(Maximum dtandardized uptake value，SUVmax)与 病灶最大直径(Maximum diameter，Dmax) 值均显著低于化疗前，差异有统计学意 义(P＜0.05)；PET/CT显像的灵敏度、特 异度、准确性分别为96.67%、94.29%、 95.38%，均显著高于对照组的76.67%、 71.43%、73.85%，差异有统计学意义(P ＜0.05)。结论 18F-FDG PET/CT显像对淋 巴瘤诊断的灵敏度、特异度、准确性较 高，能有效、准确评价淋巴瘤的治疗效 果。

Objective To explore the value of 18F-FDG PET/CT imaging in the evaluation of the curative effect of lymphoma. Methods Sixty-five cases with lymphoma were researched. The results of 18F-FDG PET/CT imaging were analyzed. Results The values of SUVmax and Dmax after chemotherapy were lower than that before chemotherapy(P ＜0.05). The sensitivity, specificity, accuracy were higher than the control group(P ＜0.05). Conclusion The value of 18F-FDG PET/CT imaging in the evaluation of the curative effect of lymphoma is good, it has high sensitivity, specificity, accuracy, which can accurately evaluate the therapeutic effect of lymphoma.
