开发基于图像的运动鲁棒扩散 MRI (dMRI) 采集框架，能够最大限度地减少刚性和非刚性运动引起的运动伪影，适用于大脑和舌头 dMRI。我们在 dMRI 中开发了一种新颖的前瞻性运动校正技术，使用基于相位图像的实时运动检测方法 (PITA-MDD) 重新采集运动损坏的图像。前瞻性 PITA-MDD 采集技术在志愿者的大脑和舌头中进行了测试。受试者被指示移动头部或吞咽以引起运动。运动检测功效通过目视检查作为黄金标准进行了验证。通过比较使用纤维束成像术（有或没有重新采集）重建的纤维束，评估 PITA-MDD 技术对扩散参数估计的影响。与目视检查相比，前瞻性 PITA-MDD 技术能够有效、准确地检测运动损坏的数据。纤维束成像结果表明，PITA-MDD 运动检测和重新采集有助于恢复大脑和舌头中丢失和畸形的纤维束，否则这些纤维束会被运动破坏并产生对扩散张量的错误估计。开发了一种用于 dMRI 采集的前瞻性 PITA-MDD 技术，可提供改进的 dMRI 图像质量以及大脑和舌头的运动稳健扩散估计。
To develop an image-based motion-robust diffusion MRI (dMRI) acquisition framework that is able to minimize motion artifacts caused by rigid and nonrigid motion, applicable to both brain and tongue dMRI. We developed a novel prospective motion-c orrection technique in dMRI using a phase image–based real-time motion- detection method (PITA-MDD) with re-acquisition of motion-c orrupted images. The prospective PITA-MDD acquisition technique was tested in the brains and tongues of volunteers. The subjects were instructed to move their heads or swallow, to induce motion. Motion-detection efficacy was validated against visual inspection as the gold standard. The effect of the PITA-MDD technique on diffusion-parameter estimates was evaluated by comparing reconstructed fiber tracts using tractography with and without re-acquisition. The prospective PITA-MDD technique was able to effectively and accurately detect motion-corrupted data as compared with visual inspection. Tractography results demonstrated that PITA-MDD motion detection followed by re-acquisition helps in recovering lost and misshaped fiber tracts in the brain and tongue that would otherwise be corrupted by motion and yield erroneous estimates of the diffusion tensor. A prospective PITA-MDD technique was developed for dMRI acquisition, providing improved dMRI image quality and motion-robust diffusion estimation of the brain and tongue.
