The early detection and management of wrist fractures may avert potential complications and patient morbidity. Five cases are described in which radiographically-occult fractures were clearly demonstrated by magnetic resonance imaging (MRI). These fractures were seen on MRI as a low signal linear band on T1- and T2-weighted images, with surrounding increased signal intensity from bone marrow oedema on T2-weighted images. In one case, intense oedema obscured the fracture line on the initial MR scan. MRI is useful in confirming the presence of a fracture, delineating its exact shape and location, and in the follow-up of these injuries during and after treatment.
手腕骨折的早期检测和处理可避免潜在的并发症及患者发病情况。本文描述了5例病例，其中磁共振成像（MRI）清晰显示了X线隐匿性骨折。这些骨折在MRI上于T1加权像和T2加权像上表现为低信号线性带，在T2加权像上周围骨髓水肿信号强度增加。在1例病例中，最初的磁共振扫描上严重的水肿使骨折线模糊不清。MRI有助于确认骨折的存在，描绘其确切形状和位置，并在治疗期间及治疗后对这些损伤进行随访。
