This work developed a new method, kf ARC, for highly accelerated MAVRIC imaging around metal implants. The proposed method utilizes both k-space correlation and spectral correlation between adjacent spectral images to improve reconstruction. kf ARC was evaluated on 2 patients with metallic implants in comparison with conventional parallel imaging. Our results show that kf ARC can significantly improve image quality at high acceleration factors and is a promising approach to fast MAVRIC data acquisition.
