摘要
磁共振弥散张量成像(DTI)是诊断和分析神经系统疾病的重要方法,但其目前发展受空间分辨率、信噪比及图像质量等限制。本文对近年来MRI系统基础质量保证方法、DTI参数定性测量方法、用于扩散成像的软件方法以及不同纤维跟踪方法等进行综述。
Magnetic resonance diffusion tensor imaging(DTI)is an important method for the diagnosis and analysis of nervous system diseases.However,the development of DTI is limited by spatial resolution,signal-to-noise ratio and image quality.Herein the basic quality assurance methods for magnetic resonance imaging systems,the qualitative measurements of DTI parameters,the software tools for DTI and different fiber tracking methods are reviewed.
