Purpose
To improve liver
mapping by incorporating adaptive neighborhood regularization into pixel‐wise curve fitting.
Methods
Magnetic resonance imaging
mapping remains challenging because of the serial images with low signal‐to‐noise ratio. In this study, we proposed to exploit the neighboring pixels as regularization terms and adaptively determine the regularization parameters according...
Purpose
Fitting the measured decay signal to the first moment in the presence of noncentral chi noise (M1NCM) can correctly address the effect of noise on the effective transverse relaxation rate (R2*) relaxometry of iron loaded liver. However, this method requires intensive computation, which restricts its application to R2* mapping. This work aims to develop a rapid implementation of the M1NCM...
