Abstract：
The paediatric metaphysis is afflicted by a wide range of pathological processes as it is the most metabolically active and well-vascularised part of the developing skeleton. This review focuses on metaphyseal marrow signal change detected with magnetic resonance imaging, which is most often occult on radiographs. When bilateral, these imaging appearances frequently present a diagnostic quandary. This review assists the radiologist to confidently dismiss physiological signal change and confidently work through the differential diagnosis. This is achieved by illustrating a practical method of classifying signal change into four categories: physiological red marrow, red marrow reconversion, marrow infiltration, and oedema-like marrow signal intensity. In doing so, various pathological entities are reviewed along with imaging pearls and next-step investigations.
摘要：
儿科干phy端受到广泛的病理过程的影响，因为它是发育中的骨骼中代谢最活跃且血管充分的部分。本文主要对磁共振成像检测的干phy端骨髓信号变化进行综述。这在射线照片上是最隐匿的。当双边时，这些影像学表现经常会出现诊断难题。这篇综述帮助放射科医生自信地消除生理信号变化，并自信地通过鉴别诊断工作。这是通过说明将信号变化分为四类的实用方法来实现的：生理红骨髓，红骨髓复变,骨髓浸润,和水肿样骨髓信号强度。在这样做的时候，对各种病理实体以及成像珍珠和下一步研究进行了审查。
