In this work, we developed a navigated Multi-Echo Data Imaging Combination (MEDIC) sequence for robust cervical spine (c-spine) imaging. In this sequence, a navigator echo is acquired in each repetition period to monitor the phase instability caused by respiration-induced field variations, and such instability among multiple echoes is subsequently compensated with a linear-phase evolution model. In vivo experimental results showed that the developed navigated MEDIC sequence outperformed the conventional MEDIC sequence and might be a potential technique for the diagnosis of cervical spine on 3T
