Improving Amide Proton Transfer-Weighted MRI Reconstruction Using T2-Weighted Images.

ABSTRACT: Current protocol of Amide Proton Transfer-weighted (APTw) imaging commonly starts with the acquisition of high-resolution T2-weighted (T₂w) images followed by APTw imaging at particular geometry and locations (i.e. slice) determined by the acquired T₂w images. Although many advanced MRI reconstruction methods have been proposed to accelerate MRI, existing methods for APTw MRI lacks the capability of taking advantage of structural information in the acquired T₂w images for reconstruction. In this paper, we present a novel APTw image reconstruction framework that can accelerate APTw imaging by reconstructing APTw images directly from highly undersampled k-space data and corresponding T₂w image at the same location. The proposed framework starts wit
