Shear wave elastography in quantitative evaluation of penile corpus cavernosum hardness / 中国医学影像技术

ABSTRACT

Objective: To explore of value of real-time shear wave elastography (SWE) in quantitative evaluation of corpus cavernosum hardness. Methods: Totally 150 healthy volunteers were divided into 5-12 years old group, 13-18 years old group, 19-30 years old group, 31-50 years old group and 51-70 years old group. Young's modulus of the corpus cavernosum was measured quantitatively with SWE imaging function. Results: The hardness of penile cavernosum increased with the increase of age. Young's modulus was (9.05±0.85)kPa in 5-12 years old group, (11.01±1.34)kPa in 13-18 years old group, (12.03±0.85)kPa in 19-30 years old group, (16.33±1.56)kPa in 31-50 years old group and (24.46±1.81)kPa in 51-70 years old group. Conclusion: SWE can be used for quantitative measurement of Young's modulus of corpus cavernosum, which is noninvasive, simple, safe and has important clinical application value.
