Gastric ulcer Radiological features
RADIOLOGICAL FEATURES OF STOMACH
Congenital hypertrophic pyloric stenosis (CHPS)
- It is a common cause of gastric outlet obstruction in infancy.
Radiological investigations-
- USG is the investigations of choice.
- Other findings-
- Cervix sign
- Antral nipple sign
- Pyloric muscle wall thickness – 4mm
- Pyloric length- ? 16mm
2. Upper GI imaging (Barium study)
- String sign- passing of small barium streak through pyloric canal
- Double/ triple track sign- crowding of muscle folds in pyloric canal
- Single bubble sign
- Catepillar sign- gastric hyperperistallic waves
GASTRIC ULCERS
Radiological signs shown by double contrast upper GIT-
- Barium filled crater
- Ring shadow
- The hallmark of benign ulcers is mucosa that is intact to the very edge of an undermining ulcer crater.
Duodenal ulcers-
- Barium meal X ray – deformed or absence of duodenal cap
- Appearance of trifoliate duodenum
