Back­ground. Mag­netic res­o­nance ­imaging (MRI) was per­formed in 18 ­male ­patients ­with 20 non­pal­pable unde­scended ­testes and the ­results ­were com­pared ­with sur­gical find­ings.
­Methods. The MRI exam­ina­tion ­located 13 (65%) of 20 ­gonads, all ­found at sur­gery. ­Eleven ­testes ­were ­found in the ­inguinal ­canal or ­just prox­imal to the ­internal ­inguinal ­ring, and two ­testes ­were dem­on­strated ­above the ­internal ­inguinal ­ring.
­Results. Of the ­seven (35%) neg­a­tive ­results, ­three ­were ­false neg­a­tive and ­four age­netic ­testes ­were not ­found sur­gi­cally. ­There was no ­false pos­i­tive ­result. ­Thus, MRI had a sen­si­tivity of 78.6% and spec­i­ficity of 100% in the dem­on­stra­tion of non­pal­pable unde­scended ­testes.
Con­clu­sions. MRI ­appears to be a ­more reli­able and non­in­va­sive ­method for the local­iza­tion of non­pal­pable unde­scended ­testes.
