Fig. 1From: Effect of renal perfusion and structural heterogeneity on shear wave elastography of the kidney: an in vivo and ex vivo studyRepresentative images of elasticity measurement by shear wave elastography (SWE) in one kidney. The regions of interest (ROIs) were positioned in the cortex, medulla and sinus of the mid-portion and in the cortex of the lower pole using the B-mode image. The lower and upper rows show the changes in the ROI by grey-scale ultrasound and SWE, respectively. The colour map is the distribution of elasticity values scaled from 0 to 180 kPa and calculated from shear wave velocity (SWV) values using Young’s modulus (YM)Back to article page
