Having trained close to 1000 veterinarians from around the world in Global FAST, AFAST, TFAST, and Vet BLUE, we have come up with our top list for image acquisition and interpretation mistakes made during Global FAST that will help synthesize the previous three excellent chapters by Dr Fulton. Whichever machine you work with, you must understand its software, how it interprets artifacts, and what its strengths and weaknesses are to gain full confidence in its imaging potential. You also need to know how to optimize image acquisition by taking advantage of external patient features and the role your hands should play. This takes time, repetition, and critical thinking during image acquisition and a sonographer who dares to use the different buttons and controls on the machine.

We strive to perform the entire Global FAST using the abdominal preset with the same curvilinear (microconvex) probe for the abdomen and thorax, including heart and lung. However, in time the sonographer may come to prefer different presets (cardiac, small parts) and probes (phased‐array, linear), depending on the structure(s) of interest, the stability of the patient and the clinical questions being addressed. However, the curvilinear (microconvex) probe is absolutely acceptable for the entire Global FAST examination.
