The edge shadowing artifact is created when the ultrasound beam strikes a curved surface, creating a dark shadow that extends from that curved surface through the far‐field. Edge shadowing most commonly occurs at the curved surfaces of stomach wall, renal cortex, gallbladder and urinary bladder and can be mistaken for free fluid along the stomach wall and renal cortex or defects in the wall of the gallbladder and urinary bladder, the latter especially when ascites is present on the AFAST CC view. See Chapter 3 for more explanation and examples.
