In this study, we present images acquired by a fast-imaging method for the evaluation of endolymphatic hydrops after intravenous administration of a single dose of gadolinium-based contrast agent. We utilized the hybrid of reversed image of MR cisternography and a positive perilymph signal by heavily T2- weighted 3D-fluid attenuated inversion recovery-multiplied by T2 (HYDROPS2-Mi2) method combined with deep learning reconstruction denoising. The scan time for the fast protocol was approximately 5 mins, which is far shorter than previously reported scan times. The fast acquisition provides similar image quality and less motion artifacts compared to the longer method.
在这项研究中，我们展示了一种快速成像方法获取的图像，用于评估单次静脉注射钆基造影剂后内淋巴积水的情况。我们利用 MR 脑池造影术反转图像和重度 T2 加权 3D 液体衰减反转恢复-多重 T2（HYDROPS2-Mi2）方法与深度学习重建去噪相结合的正外淋巴信号的混合体。快速协议的扫描时间约为 5 分钟，远短于先前报道的扫描时间。与较长的方法相比，快速采集提供了相似的图像质量和更少的运动伪影。
