Both multidetector row computed tomography (MDCT) and magnetic resonance imaging (MRI) are used to evaluate the bladder noninvasively. MDCT offers fast imaging with near-isotropic data sets optimized for three-dimensional imaging, including the latest software for volume rendering. MRI provides distinctive soft tissue contrast resolution and can perform dynamic imaging without radiation exposure. This article discusses the techniques and protocols of each modality with case illustrations of their application in a range of bladder pathologies to show their respective distinct advantages and limitations.
多排螺旋计算机断层扫描（MDCT）和磁共振成像（MRI）均用于对膀胱进行无创评估。MDCT能够快速成像，具备为三维成像优化的近各向同性数据集，包括用于容积再现的最新软件。MRI提供独特的软组织对比分辨率，并且能够在无辐射暴露的情况下进行动态成像。本文讨论了每种检查方式的技术和方案，并举例说明其在一系列膀胱病变中的应用，以展示它们各自独特的优势和局限性。
