Surface coil magnetic resonance (MR) imaging of the scrotum allows differentiation of the testis, epididymis, and spermatic cord. Intratesticular and extratesticular lesions are demarcated by the tunica albuginea. The sensitivity of MR is very high for detection of scrotal abnormalities but is non-specific since it is unable to distinguish primary testicular tumors from benign lesions. Undescended testes which lie proximal and distal to the internal inguinal ring are well visualized by MR imaging. The advantages of MR imaging in locating undescended testes is that it is noninvasive, without ionizing radiation, and capable of multiplanar images.
阴囊表面线圈磁共振（MR）成像可区分睾丸、附睾和精索。白膜可区分睾丸内和睾丸外病变。MR检测阴囊异常的敏感性很高，但缺乏特异性，因为它无法区分原发性睾丸肿瘤和良性病变。位于腹股沟内环近端和远端的隐睾通过MR成像能清晰显示。MR成像在定位隐睾方面的优势在于它是非侵入性的，无电离辐射，且能够进行多平面成像。
