To study the effect of fasting on the technical success of abdominal ultrasound examination.
In a randomized, prospective study, 150 patients for abdominal ultrasound were divided into two groups of 75 patients each with instructions to fast for six hours or have normal breakfast respectively.
The technical success of the abdominal ultrasound performed by radiologists blinded to the instruction did not differ significantly between the groups.
It appears that routine fasting before abdominal ultrasound is not necessary.
