Fig. 7.1 Typical distribution of elasticity pattern using strain elastography in a 60-year-old patient with moderate benign prostatic hyperplasia (BPH). (a) Prostate base, transverse view, left lateral rotation of the transducer. The peripheral zone (PZ) is coded with green and red colors due to soft to intermediate tissue stiffness. Some blue colors are seen at the edges of the gland corresponding to nondeformation artifacts. At the most upper and anterior part of the gland, it is difficult to separate the central zone (CZ) from the anterior fibromuscular stroma. The pericapsular elastic border is coded in red (soft) and can be seen anteriorly. (b) Prostate mid-gland, transverse view, left lateral rotation of the transducer. The peripheral zone (PZ) appears larger with the same elasticity pattern. The transition zone (TZ) exhibits a more heterogeneous pattern due to BPH development with some blue colors due to stiffer areas. The pericapsular elastic border is coded in red (soft) and can be seen laterally. (c) Prostate apex, transverse view, slight right lateral rotation of the transducer. The peripheral zone (PZ) is mainly coded in green due to intermediate elasticity. The pericapsular elastic border is coded in red (soft) and can be seen anteriorly. Note the heterogeneous pattern of the urethra with peripheral ring-shaped lines. AFS, anterior fibromuscular stroma; U, urethra.
