MRI demonstrates exquisite anatomical detail of the entire scrotum and inguinal region, adding a new dimension to the assessment of scrotal disease. MRI allows the recognition and distinction of intrascrotal structures and clearly displays their alteration in disease states. MR interpretation is based on a constellation of intrascrotal findings. A specific diagnosis frequently can be made from the MR results combined with the clinical presentation. On the other hand, MR is more expensive and time consuming than sonography and access in many geographic areas is still limited. MRI may be helpful when ultrasound is inconclusive or fails to demonstrate a clinically suspected lesion. In the author's experience, when MR has been the first imaging modality used, ultrasound has not been needed to reach a diagnosis.
磁共振成像（MRI）能清晰显示整个阴囊和腹股沟区域的精细解剖细节，为阴囊疾病的评估增添了新的维度。MRI能够识别和区分阴囊内的结构，并清晰显示它们在疾病状态下的改变。MR解读基于一系列阴囊内的表现。结合临床表现，常常能从MR结果中做出明确诊断。另一方面，MR比超声检查更昂贵、耗时更长，而且在许多地区的可及性仍然有限。当超声检查结果不明确或未能显示临床怀疑的病变时，MRI可能会有所帮助。根据作者的经验，当首次使用MR作为成像方式时，无需超声检查即可做出诊断。
