This paper reviews our recent experience imaging glass and wooden foreign bodies of the extremities with magnetic resonance (MR) and CT. In all five cases the foreign bodies were detected by CT or MR or both. Only two of the foreign bodies were detected by plain radiography. Computed tomography and MR provided additional information regarding the adjacent tendons, neurovascular bundles, and muscle groups. The surrounding inflammatory reactions were accurately compartmentalized, and the extent of the disease along anatomic pathways of potential spread was demarcated. Magnetic resonance was superior to CT in soft tissue contrast resolution. Magnetic resonance and CT are not necessary for a case of acute foreign body injuries, but in complicated cases CT and MR may not only diagnose a foreign body but also serve to guide the surgical approach and extent of exploration.
本文回顾了我们近期利用磁共振（MR）和CT对四肢玻璃和木质异物进行成像的经验。在所有5例病例中，异物均通过CT或MR或两者检测到。仅2例异物通过X线平片检测到。计算机断层扫描和MR提供了有关相邻肌腱、神经血管束和肌肉群的额外信息。周围的炎症反应被准确地划分区域，并且沿着潜在扩散的解剖途径的疾病范围被界定。磁共振在软组织对比分辨率方面优于CT。对于急性异物损伤病例，磁共振和CT并非必需，但在复杂病例中，CT和MR不仅可以诊断异物，还可用于指导手术入路和探查范围。
