To eat or not to eat? Effect of fasting prior to abdominal sonography examinations on the quality of imaging under routine conditions: A randomized, examiner-blinded trial.

Objective: Although often recommended, it is unclear whether fasting enhances the imaging quality of abdominal sonography examinations. The aim of this study was to produce experimental evidence of the effect of fasting on the imaging quality of abdominal organs.

Material And Methods: Formally consenting medical inpatients who underwent elective abdominal sonography examinations at a university medical center were randomized to either a fasting or a non-fasting preparation.
