How to do gastrointestinal contrast ultrasound

Gastrointestinal contrast ultrasonography is a safe, noninvasive method for observing the internal structure and function of the gastrointestinal tract. It requires fasting, emptying of the intestine, and oral contrast media. During the examination, the patient is required to lie on the left side and the doctor performs the ultrasound scan. Advantages include real-time observation, suitability for special populations, and limitations that observation of smaller lesions may not be as accurate as other examinations. After the examination, the doctor will give a diagnosis and recommendations based on the results. Gastrointestinal contrast ultrasound is an examination method that uses contrast agents and ultrasound technology to observe the internal structure and function of the gastrointestinal tract.
