摘要

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.
