1 Radiology Gastrointestinal Tract
2
2 Techniques Fluoroscopy , plain radiograph ( can find abnormal gas or calcification) Barium examination (BE) ( Mainly used ) CT( computed tomography)
3
3 Barium---BaSO 4 (Barium sulfate)
4
4 Oral administration barium enema
5
5 good quality Stable No absorption Cheap Few side effect No hypersensitiveness
6
6 side effect Nausea , constipation , diarrhea perforation of intestine , peritonitis , etc
7
7 Taboo Acute gastric-intestinal perforation Esophago-tracheal fistula Obstruction of colon

8 Type Ⅰ BaCl 2 + Na 2 SO 4 → BaSO 4 ↓ + 2NaCl BaCO 3 + H 2 SO 4 → BaSO 4 ↓ + H 2 O + CO 2 ↑ BaCl 2 + H 2 SO 4 → BaSO 4 ↓ +2HCl PS: BaCl 2 :barium chloride BaCO 3 :barium carbonate H 2 SO 4 :sulphuric acid HCl : hydrochloric acid NaCl : sodium chloride Na 2 SO 4 : Sodium Sulfate H 2 O : water CO 2 : carbon dioxide
