Magnetic resonance (MR) images of the scrotum were obtained at 1.5 T in 20 subjects, 13 patients with intrascrotal pathologic conditions and seven healthy subjects. Characteristic MR imaging signals obtained on T1- and T2-weighted images allowed differentiation of testis from epididymis and spermatic cord. Masses were differentiated from normal testicular parenchyma in all cases. Atrophic or ischemic testes had lower signal intensity than normal testes on T2-weighted images. Hematoma displayed a characteristic high intensity on both T1- and T2-weighted images. Intratesticular and extratesticular pathologic conditions were readily differentiated. These results suggest that MR imaging is useful in the diagnosis of scrotal and testicular abnormalities.
对20名受试者进行了1.5T的阴囊磁共振（MR）成像，其中13例患有阴囊内病理状况的患者和7名健康受试者。在T1加权和T2加权图像上获得的特征性MR成像信号可区分睾丸与附睾及精索。在所有病例中，肿块均与正常睾丸实质区分开来。萎缩或缺血性睾丸在T2加权图像上的信号强度低于正常睾丸。血肿在T1加权和T2加权图像上均显示出特征性的高强度。睾丸内和睾丸外的病理状况很容易区分。这些结果表明，MR成像在阴囊和睾丸异常的诊断中是有用的。
