Abstract

We discuss a case of a 19-year-old man with scaphoid trauma. We describe the imaging findings on three sets of radiographs, bone scintigraphy, CT and MRI. CT failed to identify a scaphoid fracture, which was present on 6 week radiographs, MRI and scintigraphy. The case illustrates that despite multidetector technology, CT still relies upon cortical and or trabecular displacement to demonstrate fractures.

摘要

我们讨论了一例19岁男性舟状骨创伤的病例。我们描述了三组X线片、骨闪烁显像、CT和MRI的影像学表现。CT未能识别出舟状骨骨折，而在6周后的X线片、MRI和闪烁显像中该骨折是存在的。该病例表明，尽管有多层探测器技术，但CT仍依赖于皮质和/或小梁移位来显示骨折。
