Abstract
Motion is a major limiting factor in abdominal MRI. Scan time is related to MR signal acquisition and k-space filling. K-space is the raw data matrix that stores digitized MR signal, which is Fourier transformed into an image. So rapid signal acquisition, reduced k-space filling, and partial Fourier techniques can reduce scan time. This article aims to provide a simplified explanation of the physics behind various techniques for fast abdominal MRI.
