眼外伤中异物伤的发生率较高,由于工业的飞速发展,人们所接触的物质愈来愈复杂,异物的性质亦多种多样。随着科学发展各种先进影象学检查手段相继问世,逐渐补充或代替传统的方法。CT 及 MRI 以其高分辨率及薄切层为诊断提供新的工具,我们以动物实验观察各种不同的异物在不同影象上的显影效果。 The incidence of foreign body injury in ocular trauma is high. Due to the rapid development of industry, people come into contact with more and more complex substances, and the nature of foreign bodies is also diverse. With the scientific development of advanced imaging methods have come out, gradually supplement or replace the traditional method. CT and MRI provide new tools for diagnosis with its high resolution and thin slice. We observed the development effects of different foreign bodies on different images by animal experiments.
