我们提出了一种采集和重建方法,旨在采集高分辨率3D快速自旋回波扩散张量图像,同时减轻DTI中的主要伪影来源-场失真、涡流和运动。所得到的图像是3D的,具有高SNR,并且是快速自旋回波,表现出大大减少的场失真。该序列利用可变密度螺旋采集梯度,允许实施自导航方案,通过该方案去除涡流和运动伪影。其结果是,产生高分辨率的3D DTI图像,而不需要涡流补偿梯度或B 0场校正。此外,一种新的方法,快速和准确的重建的非笛卡尔数据。结果在正常人类志愿者的大脑中得到证实。
We present an acquisition and reconstruction method designed to acquire high resolution 3D fast spin echo diffusion tensor images while mitigating the major sources of artifacts in DTI - field distortions, eddy currents and motion. The resulting images, being 3D, are of high SNR, and being fast spin echoes, exhibit greatly reduced field distortions. This sequence utilizes variable density spiral acquisition gradients, which allow for the implementation of a self-navigation scheme by which both eddy current and motion artifacts are removed. The result is that high resolution 3D DTI images are produced without the need for eddy current compensating gradients or B0 field correction. In addition, a novel method for fast and accurate reconstruction of the non-Cartesian data is employed. Results are demonstrated in the brains of normal human volunteers.
