Abstract
Objective The aim of this study was to assess the value of MRI to localize undescended nonpalpable testis before laparoscopy operation. Background Conventional MRI sequences when combined with diffusion-weighted imaging sequence is a good tool for tissue characterization as they provide functional and structural information about tissues. It could detect the site and viability of nondescended testes. Patients and methods During a period of 12-month duration from January 2016 to December 2016, 20 male patients ranging in age from 5 months to 25 years (mean = 9.86 ± 6.91 years) were included in this study. All patients selected were referred to the MRI scanning for assessment of nonpalpable undescended testes that are clinically diagnosed before laparoscopy. Results Conventional MRI combined with diffusion-weighted images gives better results as regards the location of undescended testis and also detection of viability of testicular tissue. This technique had the highest sensitivity (100%), specificity (90%), and accuracy (90%). Conclusion Conventional MRI with fat-suppression technique when combined with diffusion-weighted imaging gives the highest accuracy for localization and detection of viability of undescended nonpalpable testis.
