| 中文摘要: |
| 磁共振扩散加权与弥散张量成像作为磁共振成像新技术已经应用于临床。迫切要求我们对这两种成像方法有较全面的认识和准确的把握。本文全面系统地介绍磁共振扩散加权与弥散张量成像的原理,阐明相关概念,分析重要成像参数的影响及二者的差别。 |
| 英文摘要: |
| As new technologies of magnetic resonance imaging, diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI) have been applied in clinical diagnosis. So it is extremely necessary for us to have a clear cognition of what are DWI and DTI and how they work. This article illustrates the principle of DWI and DTI, and gives precise explanations of some relative conceptions, further more it analyzes some affecting factors and the differences between DTI and DWI. |
