Objective To investigate the diagnostic value of the instant gastrointestinal ultrasound contrast agent in the digestive diseases. Methods Five hundred and seventy-nine patients received the examination of the color Doppler after they drinked the ultrasonic contrast agent. Then the results were analyzed by consistency analysis. Results There was high consistency between the two examinations in the normal control, gastritis, peptic ulcer, gastric cancer and gastric leiomyoma. The Kappa value was 0.768, 0.913, 0.925, 0.939 and 1.000, respectively. But the consistency in the gastric polyp was low , the Kappa value was 0.368. Conclusion The color Doppler through the instant gastrointestinal ultrasound contrast agent has high diagnostic value in the common diseases of the digestive system.
