Abstract
MRI offers an alternative to CT, and thus is central to an ALARA strategy. However, long exam times, limited magnet availability, and motion artifacts are barriers to expanded use of MRI. This article reviews developments in pediatric body MRI that might reduce these barriers: high field systems, acceleration, navigation and newer contrast agents.
摘要
MRI 为 CT 提供了一种替代方法，因此是 ALARA 策略的核心。然而，长时间的检查时间、有限的磁体可用性和运动伪影是限制 MRI 广泛应用的障碍。本文综述了可能降低这些障碍的儿科体部 MRI 的新进展：高场系统、加速、导航和新型对比剂。
