“…However, this number exceeded those of other studies investigating the same topics. 13,14 Moreover, the level of significance in most statistical analyses regarding the other study variables in this work was strong (P < .001), which may have compensated for the small sample size. Third, the process of elastographic imaging was not completely blinded, as the operator was aware of the varicocele grade when performing the testicular duplex assessment.…”

“…In the study by Abdelwahab and colleagues, preoperative testicular elastography results were found to be a possible predictor of semen analysis changes before and after varicocelectomy 28 . Authors showed a statistically significant negative correlation between the SWE stiffness index and both sperm count and total motility.…”

Shear wave elastosonography (SWE) is a non-invasive ultrasound (US) imaging modality used to assess the mechanical properties of tissues such as rigidity and elasticity. 1 This technique allows the evaluation of the degree of fibrosis caused by parenchymal alterations in several organs such as liver, kidney, muscle, thyroid and breast. 2-8 As a semi-quantitative elastographic technique, SWE compares the elasticity and stiffness of target tissues with nearby normal ones. 9 As described by Aigner et al, the use of SWE for the evaluation of testicular tissues is a new concept with high sensitivity rate

“…Colour Doppler US (CDUS) and contrast harmonic imaging assessed changes in intratesticular microcirculation in varicocele, reporting reduced arterial perfusion in testes with varicocele and defective spermatogenesis (Akcar, Turgut, Adapinar, & Ozkan, ; Semiz et al, ; Tarhan, Ucer, Sahin, & Gumus, ; Unsal, Turgut, Taşkin, Koşar, & Karaman, ; Ur Rehman, ; Zhang, Du, Liu, Qi, & Chu, ). Lower elastography values have been reported in testes with varicocele, and a negative correlation between varicocele grade and elasticity values has been noted (Abdelwahab et al, ; Caretta et al, ; Dede et al, ). A limited number of studies have assessed the role of diffusion weighted imaging (DWI) with measurement of testicular apparent diffusion coefficient (ADC) in the assessment of patients with varicocele (Çekiç et al, ; Karakas et al, ; Yıldırım, Sağlık, & Çelik, ).…”

A noninvasive imaging technique providing information about testicular dysfunction in testes with varicocele would be useful. The aim is to measure the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) in testes of infertile men with varicocele and to assess interobserver agreement. Sixteen infertile men with varicocele and 14 age‐matched controls underwent 1.5 T diffusion tensor imaging (DTI) MRI. Testicular ADC and FA were measured by two radiologists independently. Parametric and nonparametric statistical tests were applied to compare between the ADC and FA of testes with varicocele and normal testes. Interobserver agreement was evaluated. The interobserver variability for ADC (0.915) and FA (0.948) was very good. No differences in ADC (p = 0.294) were found between the two groups. FA was significantly lower in testes with varicocele compared to age‐matched controls (p < 0.001). An optimal cut‐off of FA 0.08 was found for the diagnosis of varicocele (sensitivity = 88%, specificity = 93.5%, positive predictive value = 91.6% and negative predictive value = 90.6%). Based on our results, FA is useful for the diagnosis of testes in infertile men with varicocele, with very good interobserver agreement. Therefore, DTI may be used as a noninvasive imaging tool in the work‐up of varicocele.
