Efficacy for asymmetric Fast 3D wheel technique on female pelvic MRI on contrast enhanced 3D T1-weighted image

Motivation: Fast 3D Wheel with Sequential filling and Asymmetric Fourier imaging (Fast 3Dwsa) which is one of the k-space based acceleration techniques can improve image quality and acquisition time. Goal(s): The goal was to determine the utility of contrast-enhanced 3D T1-weighted image with Fast 3Dwsa on female pelvic MRI as compared with conventional parallel imaging (PI) and compressed sensing (CS). Approach: Quantitative and qualitative indexes for image quality improvement and reducing acquisition time were statistically compared among all methods. Results: Quantitative and qualitative indexes of Fast 3Dwsa was significantly better than that of PI and CS (<0.05). Impact: Fast 3Dwsa is considered as useful for image quality improvement with reducing acquisition time on female pelvic MRI, when compared with conventional PI as well as CS.
