| 摘 要:［目的］ 探讨18F-FDG PET/CT在胃部良恶性疾病鉴别诊断中的作用。［方法］ 回顾性分析49例临床可疑胃部疾病患者行18F-FDG PET/CT显像的结果。分析病灶分布特点、厚度及标准化摄取值最大值（SUVmax）。［结果］胃部良、恶性病灶的厚度分别为（13.800±3.489）mm、（18.088±8.575）mm，差异具有统计学意义（t=-2.486，P=0.017）；胃部良、恶性病灶的早期相SUVmax分别为3.607±2.710、7.277±6.175，差异具有统计学意义（t=-2.891，P=0.006）；胃癌组早期相与延迟相SUVmax分别为5.131±2.486与6.156±3.126（t=-3.691，P=0.002）；胃淋巴瘤组则分别为9.183±7.770与11.744±10.222（t=-4.095，P=0.001），差异均有统计学意义。［结论］ 18F-FDG PET/CT显像在胃部良恶性疾病鉴别方面具有重要作用。 |

| Abstract:［Prupose］ To study the value of 18F-FDG PET/CT imaging in the differential diagnosis of gastric diseases. ［Methods］ Forty-nine patients clinically suspicious of gastric diseases underwent 18F-FDG PET/CT，and the data including distribution，thickness，the maximum of standard uptake value (SUVmax) of lesions were reviewed. ［Results］ Thickness of the benign and malignant lesions was (13.800±3.489)mm and (18.088±8.575)mm respectively(t=－2.486，P=0.017)，with significant difference between them. The SUVmax of early-phase of the benign and malignant lesion was 3.607±2.710 and 7.277±6.175 respectively(t=－2.891，P=0.006)，with significant difference. The SUVmax in early-phase and delay-phase of gastric carcinoma was 5.131±2.486 and 6.156±3.126 respectively(t=-3.691，P=0.002)，and that in lymphoma was 9.183±7.770 and 11.744±10.222 respectively(t=-4.095，P= 0.001)，both with significant difference. ［Conclusions］ 18F-FDG PET/CT imaging has certain value in the differential diagnosis of benign and malignant diseases of stomach. |
