ABSTRACT：Gastric contrast-enhanced ultrasound includes oral contrast-enhanced ultrasound（OCUS） and double contrast-enhanced ultrasound （DCEUS），which can provide valuable clinical information about tumor morphology，vascular characteristics，and treatment responses. OCUS can clearly identify the gastric wall structure and the extent and depth of lesions by applying oral contrast agents.DCEUS，based on OCUS combined with venography，can display theanatomical and perfusion characteristics of lesions.In recent years，gastric contrast agents and imaging techniques have developed rapidly. However，the clinical application of gastric contrast-enhanced ultrasound is still inthe developmental stage.Thisarticle reviews the clinical status of OCUSand DCEUS in the screening，diagnosis，staging，pathological typing，and treatment evaluation of gastric cancer.Studies have shown that gastric contrast-enhanced ultrasound has high sensitivity and specificity in the assessmentof diagnosis and T-staging of gastriccancer.Furthermore，gastriccontrast-enhanced ultrasound has the advantages of being cost-effective，convenient，non-invasive，free from radiation exposure，real-time，and easy to repeat.In the diagnosisandtreatmentof gastriccancer，it is expected to become one of the important imaging assessment tools.
