This is an overview of the current applications of magnetic resonance imaging (MRI) in the genitourinary tract based on the experience with the 0.5-Tesla MR scanner (Gyroscan, Philips) at the Leiden University Hospital and on reports in the literature. MRI appears to share some of the limitations of CT. MRI cannot reliably differentiate between a malignant and a benign tumor. In the staging of ovarian malignancies by means of MRI, bowel preparation would be desirable. On the other hand, the soft-tissue contrast resolution of MRI is superior to that of CT and images can be obtained in any plane. Thus MRI promises to be an accurate method for staging malignancies. The results in the examination of transplant kidneys are encouraging. We expect that there will be a place for MRI as a complementary technique to ultrasonography in the diagnosis of scrotal disease.
本文基于莱顿大学医院0.5特斯拉磁共振扫描仪（飞利浦Gyroscan）的使用经验及文献报道，对磁共振成像（MRI）在泌尿生殖道的当前应用进行综述。MRI似乎存在一些与CT相同的局限性。MRI无法可靠地区分恶性肿瘤和良性肿瘤。在通过MRI对卵巢恶性肿瘤进行分期时，肠道准备是可取的。另一方面，MRI的软组织对比分辨率优于CT，并且可以在任何平面获取图像。因此，MRI有望成为一种准确的恶性肿瘤分期方法。移植肾检查的结果令人鼓舞。我们预计，在阴囊疾病的诊断中，MRI作为超声检查的补充技术将占有一席之地。
