The radiological measurement of oesophageal stricture diameter.
A radiographic method of measuring the diameter of oesophageal strictures is described. Both a liquid bolus and a solid sphere were used. The measurements obtained were compared with measurements obtained at endoscopy. It is suggested that the most effective method is to determine the maximum size of barium sphere which will pass through a stricture.
