Today's Daily Dose: Contrast radiography

Untitled Document
“Ulcerations are seen as out-pouching of contrast on positive-contrast studies, because the contrast accumulates in the crater of the ulcer, if the ulcer is tangential to the X-ray beam. When the X-ray beam strikes the ulceration perpendicularly, the lesion is seen 'en face' and appears as a focal pool of contrast medium surrounded by a lucent line representing a rim of wall thickening.”
