T2WI is a key component of mpMRI in prostate. 2D T2WI obtained in multi plane is recommend in PI-RADS v2, resulting in prolonged examination time. The usefulness of 3D-VRFA-TSE, which has a potential to reduce scan time by multiplanar postprocessing reconstruction of images into any desired plane, has been reported. As an further effective way to accelerate scan time is provided by C-SENSE, which uses undersampling of the k-space, we compared 3D-VRFA-TSE with 3D-VRFA-TSE with C-SENSE. C-SENSE enables a reduction in acquisition time of 40% in 3D-VRFA-TSE, maintaining image quality and lesion conspicuity except for clarity of prostatic capsule.
