Due to low costs and common availability, ultrasonography and computed tomography still represent the most common diagnostic tools in uroradiology. However, magnetic resonance imaging (MRI) is gaining more and more importance since this imaging modality allows for a comprehensive examination of almost the complete spectrum of urologic diseases, including congenital malformations. The most important advantages of MRI are the free choice of slice orientation, high soft tissue contrast and high resolution as well as the lack of radiation. Technical progresses in hard and software components have led to a reduction in acquisition time, allowing for real-time imaging as well as MR angiography and MR urography with a significant reduction in motion artifacts. In addition, contrast enhanced MRI represents the imaging modality of choice in patients with reduced renal function or known allergy against iodinated contrast agent.
由于成本低廉且普遍可得，超声检查和计算机断层扫描仍是泌尿放射学中最常用的诊断工具。然而，磁共振成像（MRI）正变得越来越重要，因为这种成像方式能够对几乎所有泌尿系统疾病谱进行全面检查，包括先天性畸形。MRI最重要的优点是可以自由选择切片方向、软组织对比度高、分辨率高以及无辐射。硬件和软件组件的技术进步已使采集时间缩短，从而实现实时成像以及磁共振血管造影和磁共振尿路造影，同时显著减少运动伪影。此外，对比增强MRI是肾功能减退或已知对碘造影剂过敏患者的首选成像方式。
