Images obtained from a 60-year-old male with a PSA level of 305.22 ng ml⁻¹. The patient has no special discomfort, only the serum PSA was significantly increased during his healthy physical examination. Then he underwent SWE examinations and TRUS-guided systematic biopsy of the prostate. (a.) Young’s modulus of the prostate gland were measured by SWE. Emax was 241.8 kPa, Emean was 114.5 kPa and Emin was 48.8 kPa. (b.) Histological image of the prostate gland (hematoxylin and eosin stain,×10).Final diagnosis was prostate cancer, and the Gleason scores was 4 + 4=8. Emax = maximum Young’s modulus; Emean = mean Young’s modulus; Emin = minimum Young’s modulus.
