MR Imaging Evaluation of the Testes and Scrotum

MR imaging of the scrotum is a valuable adjunct to ultrasonography, offering superior soft tissue contrast resolution and multiplanar imaging capabilities for evaluating scrotal abnormalities. While ultrasonography is the first-line imaging modality to evaluate scrotal pathology, MR imaging is particularly useful when sonographic findings are inconclusive. In these instances, MR imaging aids in lesion localization, characterization of extratesticular pathologies, and surgical planning. MR imaging also plays a role in local staging of testicular neoplasms, evaluating undescended testes, and assessing acute scrotal conditions. Emerging applications, including radiomics and diffusion tensor imaging, demonstrate promise in the assessment of select testicular pathologies.
