Improvement in B1‐inhomogeneity artifacts in the abdomen at 3T MR imaging using a radiofrequency cushion

Abstract

The RF cushion significantly improves image quality for abdominal imaging at 3T by reducing or eliminating B1-inhomogenity artifacts. This improved image quality is seen on turbo spin echo-based T2-weighted imaging such as HASTE but does not apply to gradient echo-based T2-weighted imaging such as the true-FISP sequence.
