要旨●胃癌のX線診断では,胃全体像から萎縮や胃炎の程度,範囲などからH. pylori感染状況も考慮した背景粘膜診断を行い,組織型,肉眼型との関係をもとに,癌の表面形態から粘膜層の組織型診断や範囲診断を,深部形態の胃壁の厚みや伸展不良・硬化所見から粘膜下層以深における癌浸潤や線維化を読影して深達度診断や範囲診断を行い,治療方針決定に役立てている.本稿では,X線診断の要点を実際の症例を用いて解説した.
With the increased rate of Helicobacter pylori eradication, the incidence of gastric cancer has increased. The background of gastric mucosa changes. In the diagnosis of gastric cancer using X-rays, the type of gastric cancer was identified based on macroscopic findings. In addition, we diagnosed the depth of gastric cancer from the form of the deep part. With the help of X-ray images, accurate preoperative diagnosis with much information was possible. Thus, here we report the diagnosis of early gastric cancer using X-rays.
