Abstract
We made an in vitro model of a wooden foreign body using both fresh and dry pine wood in both fat and soft-tissue background mediums. Air/wood/background medium interfaces were studied with MR and CT to determine which method provided the best image contrast for detecting a wooden foreign body. CT was demonstrated to be superior to MR in the evaluation of the orbit in the in vitro model.
摘要
我们使用新鲜和干燥的松木，在脂肪和软组织背景介质中制作了木质异物的体外模型。利用磁共振成像（MR）和计算机断层扫描（CT）研究空气/木材/背景介质界面，以确定哪种方法在检测木质异物时能提供最佳的图像对比度。在体外模型中，CT在眼眶评估方面被证明优于MR。
