WebTissue echogenicity When an echo returns to the transducer, its amplitude is represented by the degree of brightness (i.e. echogenicity) of a dot on the display. Combination of all the dots forms the final image. Strong specular reflections give rise to bright dots (hyperechoic) e.g., diaphragm, gallstone, bone, pericardium. Weaker diffuse reflections produce grey … WebFocused cardiac ultrasound (FoCUS) refers to the use of ultrasound imaging to evaluate cardiac structure and function at the bedside by a treating physician. In recent years, FoCUS has become an indispensable first-line diagnostic tool, complementing the traditional physical examination and accelerating patients’ evaluation in acute care ...
