Applicability of the 3D-VIBE sequence to whole brain imaging

Abstract

The VIBE method has been developed imaging also holds its breath in an abdomen, and to do three-dimensional T1WI in possible time in gradient echo sequence, and applied to dynamic study mainly and planning for time reduction using an interpolation and partial fourier. We considered the condition for imaging to do whole brain as high resolution image using VIBE. Even if base matrix was maintained when an interpolation and partial fourier were used too much excessively by Phantom experiment, the resolution of MPR image fell. There was a limit of the interpolation therefore to maintain the resolution as voxel. SNR fell by FA increase by the applicability to the head, and peak existed in about 15 degrees in CNR of white matter and gray matter. Therefore by it's clinical and optimizing the imaging condition of VIBE, whole brain, it was imaging possible in about 3 minutes as high resolution image.
