MRI offers the best soft-tissue contrast of any radiographic modality. It provides better delineation of soft-tissue tumors and bone tumors than CT, but several different pulse sequences may be needed to make optimum use of this potential. MRI is also well suited to evaluation of abnormalities of the bone marrow, as it is not subject to the dense bone artifact that may occur with CT. Changes in signal intensity may be used to gain some appreciation of blood flow in the major vessels. Examples of each of these applications are discussed.
磁共振成像（MRI）在所有放射成像方式中提供最佳的软组织对比度。与计算机断层扫描（CT）相比，它能更好地描绘软组织肿瘤和骨肿瘤，但可能需要几种不同的脉冲序列才能充分利用这一潜力。MRI也非常适合评估骨髓异常，因为它不会受到CT可能出现的致密骨伪影的影响。信号强度的变化可用于对主要血管中的血流情况有一定了解。将讨论这些应用中的每一个示例。
