Typically, the sonographer should stay away from the area of the stomach during the DH view by directing the probe far cranially, striving for the proportionality shown (see Figures 6.15 and 6.16). The stomach has a sonolucent (dark or black) component to its wall, which typically appears linear in real‐time imaging but can appear as an anechoic triangulation like free fluid. The stomach wall is also subject to artifacts such as edge shadowing (see Figure 3.2). The best way to avoid being confounded by the stomach is to stay further cranially when interrogating the DH view, understanding that little is gained by imaging caudally toward the stomach during an AFAST (see Figure 5.10). Free intraabdominal fluid is most commonly, easily, and accurately seen between liver lobes along the diaphragm, or between the liver and diaphragm (see Figure 6.10).

Pearl: Stay away from the stomach region because it is too far caudal for the DH view. Free fluid is better appreciated between the liver and diaphragm, between liver lobes more cranially along the diaphragm, and the liver and falciform fat.
