From: First-in-human diagnostic study of hepatic steatosis with computed ultrasound tomography in echo mode

a, b Echo intensity (left column) and speed-of-sound (SoS) distribution (right column) in a steatotic and normal liver with median controlled attenuation parameter (CAP) values of 331 dB/m and 171 dB/m, respectively. In each case, we show images corresponding to three distinct data acquisitions (rows) to illustrate the repeatability of CUTE-SoS and the correspondence between structures in B-mode and CUTE-SoS images. White dotted lines in the first row in (b) show an example of the manually selected region of interest (ROI) with blood vessels (dark areas) excluded, from which we extracted the mean liver SoS value. AW abdominal wall, L liver.
