title: Testicular microlithiasis and preliminary experience of acoustic radiation force impulse imaging.
abstract: BACKGROUND
  Elastography of the testis can be used as a part of multiparametric examination of the scrotum.
  
  
  OBJECTIVE
  To determine the testicular stiffness using acoustic radiation force impulse imaging (ARFI) technique in men with testicular microlithiasis (TML).
  
  
  METHODS
  In 2013, 12 patients with diagnosed testicular microlithiasis in 2008 (mean age, 51 years; age range, 25-76 years) underwent a 5-year follow-up B-mode ultrasonography with three ARFI elastography measurements of each testis. We used a Siemens Acuson S3000 machine.
  
  
  RESULTS
  No malignancy was found at the 5-year follow-up B-mode and elastography in 2013. However, we found an increase in TML; in the previous ultrasonography in 2008, eight men had bilateral TML, whereas in 2013, 10 men were diagnosed with bilateral TML. The mean elasticity of testicles with TML was 0.82 m/s (interquartile range [IQR], 0.72-0.88 m/s; range, 65-1.08 m/s).
  
  
  CONCLUSIONS
  Elastography velocity of testis with TML seems to be in the same velocity range as in men with normal testis tissue.
