2. Some factors affecting abdominal ultrasound
Patients with obesity often accumulate food in the stomach and intestinal gas, affecting the ultrasound results, missing lesions. Therefore, patients should limit eating foods that are difficult to digest, greasy and easy to cause bloating. Food is in the stomach. Food in the stomach makes it impossible to visualize the entire structure of the stomach with an abdominal ultrasound. Therefore, before the abdominal ultrasound, it is necessary to fast for 6-8 hours before the examination, if necessary to evaluate the pathology of the gallbladder and biliary tract. Less urine in the bladder. The patient has just finished urinating or drinks little water, which leads to limited observation of the pelvic region and misses some pathologies in the pelvic region.

3. Why is it important to drink a lot of water and hold in urine during general abdominal ultrasound?
The need for urine in the bladder is because the water in the bladder creates a sound medium for the ultrasound waves to pass through (providing a good environment for sound). Withholding urination causes bladder distension and gives accurate ultrasound results when evaluating structures in the pelvic region such as the bladder, prostate gland, and uterus. More urine in the bladder causes the bladder to stretch, which makes the position of the uterus pushed up more easily visible. The distended bladder is easy to see the organs in the pelvis because it is not obscured by bowel loops. For fetal ultrasound. Gestational age before 20-24 weeks or earlier is particularly demanding because transducer ultrasound requires water in the bladder. This will help the ultrasound to travel faster for a clear picture of the uterus. During ultrasound, it is necessary to hold urine for the purpose of having a full bladder to give a better ultrasound image. Water in the bladder can create a favorable environment for ultrasound and sound rays to pass through, so it will give the best fetal ultrasound images and sounds.
