Objective To explore the preliminary application method and diagnostic value of virtual touch tissue imaging quantification (VTIQ) in diffuse testicular diseases of male infertility. A total of 70 male examiners in our hospital from June 2019 to March 2020 were selected as the research objects. According to whether the subjects are sick (testicular microlithiasis, varicocele), all subjects are divided into three groups: normal group, testicular microlithiasis group, and varicocele group. Whether there is a difference between the groups, and analyze whether there is a correlation between the index reflecting the quality of the semen and the testicular shear wave velocity. The measurement of different positions in the testis will affect the magnitude of the shear wave velocity (P < 0.05). The shear wave velocities of the testes of different diseases are obviously different from the normal side. At the same time, postural changes will have a certain impact on the shear wave velocities of both testes (all P < 0.05). There is a certain correlation between the testicular shear wave velocity and the conventional semen quality index (total sperm motility (P < 0.05)) of the subjects. Acoustic palpation tissue imaging quantitative technology can be applied to the diagnosis of male testes and testicular-related diseases (especially diffuse testicular diseases), and is more suitable for male infertility, which can provide clinical diagnosis and treatment options certain imaging basis.
