Figure 1: Ultrasound images of rabbit penis. Grayscale images showed no plaque or calcification in the penile tissue in either group before and after TGF-β1 injection. 2D-SWE images showed that: before TGF-β1 injection, the 2D-SWE image colors of rabbit penis were similar between TGF-β1 and control groups; after TGF-β1 injection, the image colors of rabbit penis differed between TGF-β1 and control groups. (a) Ultrasound image from a rabbit in the TGF-β1 group euthanized on the day of injection, before TGF-β1 injection. (b) Ultrasound image from a rabbit in the control group euthanized on the day of injection, before TGF-β1 injection. (c) Ultrasound image from a rabbit in the TGF-β1 group obtained from rabbits euthanized at 20 days after TGF-β1 injection. (d) Ultrasound image from a rabbit in the control group euthanized at 20 days after TGF-β1 injection. Q-Box™: measurement results of 2D-SWE; Min: minimum; Max: maximum; s.d.: standard deviation; Diam: diameter; TGF-β1: transforming growth factor β1; 2D-SWE: two-dimensional shear wave elastography. Arrow: skin; circle: tunica albuginea.
