Comparison between radiologic and endoscopic-bioptic examinations shows that, in early cancer, great demands are made on the radiologic technique and experience of the examiner. An integrated technique using relief- and double-contrast with additional induced hypotony can achieve demonstration of circumscribed shallow changes of less than 2 cm diameter in all segments of the stomach. With this technique over 80% of early cancers can be detected radiologically.
放射学检查与内镜活检检查的比较表明，在早期癌症中，对放射学技术和检查者的经验要求很高。采用气钡双对比加额外诱导低张的综合技术，能够显示胃各部位直径小于2厘米的局限性浅表病变。运用该技术，超过80%的早期癌症能够通过放射学检查被发现。
