Diffusion tensor imaging (DTI) is a powerful magnetic resonance imaging (MRI) technique that enables the measurement of the structural integrity of neural tissue. DTI allows for the visualisation of changes within neural tracts in conditions such as stroke, brain tumours, multiple sclerosis, Parkinson...
磁共振弥散成像技术是目前在活体上测量水分子弥散运动与成像的唯一方法,最常用的主要包括弥散加权成橡(diffusion weighted imaging,DWI)和弥散张量成像(diffusion tensor imaging,DTI)。DTI在中枢神经系统尤其对白质和灰质的区别以及白质纤维的走行有很好...
View PDF View chapter About the book Description The concepts behind diffusion tensor imaging (DTI) are commonly difficult to grasp, even for magnetic resonance physicists. To make matters worse, a many more complex higher-order methods have been proposed over the last few years to overcome the ...
This unit provides step‐by‐step instructions on how to perform diffusion tensor imaging (DTI) in a clinical setting. A brief introduction on DTI techniques and current clinical applications is also presented. Additional technical details, practical considerations, and anticipated results are discussed ...
