Comparing biceps brachii intramuscular blood perfusion between imaging techniques using the vascularity index

Intramuscular blood perfusion of the biceps brachii muscle was measured with color Doppler flow imaging (A, C) and Angio PLanewave UltraSensitive Imaging (B, D). Isolated color pixels were used to calculate the vascularity index for dominant (A, B) and non-dominant (C, D) biceps brachii muscles. This bilateral comparison of images obtained for a single participant indicate Angio PLanewave UltraSensitive Imaging was relatively more sensitive than color Doppler flow imaging in detecting intramuscular blood flow of the biceps brachii muscle
