The three-dimensional (3D) high resolution volume isotropic FSE sequence of ankle magnetic resonance imaging has the capabilities of acquiring thin-sliced sections and performing MPR, at the cost of long scan time. Several recent studies showed that the compressed sensing(CS) helps to reduce scan time, which is especially beneficial in 3D imaging. The aim of this study was to investigate the feasibility of 3D VISTA imaging with CS in ankle joint imaging, in comparison to 3D-VISTA with parallel imaging (PI ). The results showed that the acquisition time of 3D-VISTA MRI was reduced with CS while the image quality was retained.
