OBJECTIVES
To compare the accuracy rates of the detection and staging of oesophago and gastric carcinomas between PET/MRI and PET/CT.
METHODS
An extensive librarian-led literature search of PubMed, Embase, Web of Science, the Cochrane Central Library, and CNKI was performed and a meta-analysis was done.
RESULTS
Six studies, including 123 participants, were analyzed. PET/MRI had a comparatively high sensitivity in primary lesion detection compared with PET/CT. (RR = 1.14, 95% CI 1.01-1.29, P = 0.036).PET/MRI had no significant statistical differences in all aspects of TNM staging compared with PET/CT.
CONCLUSIONS
This systematic review confirmed the advantage of PET/MRI in detecting oesophago and gastric carcinomas.Compared with PET/CT, it can reduce unnecessary radiation exposure and can be used in relevant patients without contraindications of MRI.
目的
比较正电子发射断层扫描/磁共振成像（PET/MRI）与正电子发射断层扫描/计算机断层扫描（PET/CT）对食管癌和胃癌的检测及分期准确率。
方法
由图书馆员主导，对PubMed、Embase、科学引文索引（Web of Science）、考克兰系统评价数据库（Cochrane Central Library）和中国知网（CNKI）进行全面的文献检索，并进行荟萃分析。
结果
分析了6项研究，共123名参与者。与PET/CT相比，PET/MRI在原发灶检测方面具有较高的敏感性。（相对危险度（RR）=1.14，95%置信区间（CI）1.01 - 1.29，P = 0.036）。与PET/CT相比，PET/MRI在TNM分期的各个方面均无显著统计学差异。
结论
本系统评价证实了PET/MRI在检测食管癌和胃癌方面的优势。与PET/CT相比，它可以减少不必要的辐射暴露，可用于无MRI禁忌证的相关患者。
