Radiography: barium series

Contributor(s): Barbara J Watrous

Introduction

  • Administration of positive contrast agent to provide information about the lumen of the gastrointestinal tract and to give crude assessment of gastrointestinal transit time.
  • Visualisation of mucosal surfaces of gastrointestinal tract.
  • Allows assessment of gastrointestinal wall thickness.

Uses

Advantages

  • Simple.
  • Relatively non-invasive.

Disadvantages

  • Time-consuming and moderately expensive, ( cost may be comparable to exploratory laparotomy).
  • May give minimal information if total gastrointestinal obstruction as barium may not reach the site of obstruction.
  • Often normal in cases of chronic diarrhea.
  • Does not provide information about large intestine (a barium enema Radiography: large intestine contrast or pneumocolon is required).
