食道X線造影—スクリーニング検査と精密検査のポイント

X-ray Examination of the Esophagus, Point of X-ray Screening and Detail Examination for Esophageal Cancers

要旨●食道X線造影検査について，スクリーニング検査と精密検査との立場から，それぞれの撮影法および読影のポイントについて述べた．スクリーニングX線検査では，食道表在癌拾い上げ診断の実際について，また精密X線検査では，実際の撮影手順と所見の捉え方，読影に必要な病変の描出方法や周囲粘膜を含めた画像のあり方，深達度診断では特に側面変形の重要性について述べた．形態診断としてのX線造影検査の有用性を改めて見つめ直すきっかけとなれば幸いである．

　Regarding X-ray examination of the esophagus, we wrote points of each radiography and reading film with screening and detailed examination. X-ray screening for superficial cancers of the esophagus is effective. In the detailed examination, radiography procedure and how the esophageal cancer should be described, and the image including the background of the lesion is necessary for reading films, and the lateral deformity is important, particularly for diagnosing the depth of invasion. We want to appeal for the usefulness of X-ray examination for morphological analysis.
