ULM Backscattering imaging offers better vessel delineation than MB count ULM. (A) Left: MB count ULM map of blood vessels in a rat brain coronal plane. Right: Corresponding normalized backscattering amplitude ULM map. (C) Zoom in the thalamus corresponding to the blue box in (A): MB count (left) and backscattering (right) maps in dB. The image log-dynamic is set by the noise level determined in areas surrounded by a white dash line. (C) Same analysis as in (B) for another thalamus area in a second animal. Green arrows depicts better small vessel delineation in backscattering imaging.
