Study on the method of ultrasonic measurement for gastric emptying function

Objective To search one ultrasonic method which could evaluate gastric emptying function accurately.Methods The gastric emptying time of 74 normal volunteers were measured by radioisotope scanning and different ultrasonic methods which including gastric antrum area,gastric antrum volume and whole gastric cylinder method.Results The gastric emptying time measured by whole gastric cylinder method related best with those measured by radioisotope scanning (r =0.79).The gastric emptying time was no significant difference between the cylinder method and radionuclide scanning (P ＞0.05).Compared with radionuclide scanning,those measured by gastric antrum area and gastric antrum volume had significant differences.Conclusions The whole gastric cylinder method can accurately reflect the gastric emptying function.
