The aim of this study was to reduce the scan time of 3D Nerve-view using Compressed Sensing-Sensitivity Encoding (CS), and evaluate the image quality and capability of diagnosis of accelerated 3D Nerve-view sequences. 3D Nerve-view sequences with 5 different CS (compressed sense technology) accelerating factors (4,6,8,10,15), and a traditional 3D Nerve-view with 4-fold parallel imaging (sense) as a clinical reference were obtained.The 3D-CS sequence offer comparable diagnostic quality to the clinical 3D scan with much less time, potentially increasing the productivity of MR scanners.CS-3D Nervview with factor 6 offer equilibrium between comparable clinical diagnostic quality with less scan time (235seconds).
