Images obtained from a 65-year-old male with a PSA level of 9.12 ng ml⁻¹. The patient was in hospital because of symptoms of frequent micturition and dysuria, 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 41.4 kPa, Emean was 27.0 kPa and Emin was 10.7 kPa. b.) Histological image of the prostate gland (hematoxylin and eosin stain,×10).Final diagnosis was benign prostatic hyperplasia. Emax = maximum Young’s modulus; Emean = mean Young’s modulus; Emin = minimum Young’s modulus.
