Simultaneous Multislice Echo Planar Imaging With Blipped Controlled Aliasing in Parallel Imaging Results in Higher Acceleration: A Promising Technique for Accelerated Diffusion Tensor Imaging of Skeletal Muscle.
OBJECTIVE The aim of this study was to investigate the feasibility of accelerated diffusion tensor imaging (DTI) of skeletal muscle using echo planar imaging (EPI) applying simultaneous multislice excitation with a blipped controlled aliasing in parallel imaging results in higher acceleration unaliasing technique. MATERIALS AND METHODS After federal ethics board approval, the lower leg muscle...
متن کاملControlled Aliasing In Parallel Imaging
Recently a new parallel imaging strategy, Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration (CAIPIRINHA), was introduced, which modifies the appearance of the aliasing artifacts during the acquisition in order to improve the following parallel imaging reconstruction procedure. This concept was successfully applied to simultaneous multi-slice imaging (MS-CAIPIRINHA) [1] and ...
متن کاملRARE/turbo spin echo imaging with Simultaneous Multislice Wave-CAIPI.
PURPOSE To enable highly accelerated RARE/Turbo Spin Echo (TSE) imaging using Simultaneous MultiSlice (SMS) Wave-CAIPI acquisition with reduced g-factor penalty. METHODS SMS Wave-CAIPI incurs slice shifts across simultaneously excited slices while playing sinusoidal gradient waveforms during the readout of each encoding line. This results in an efficient k-space coverage that spreads aliasing...
متن کاملThree-dimensional echo planar imaging with controlled aliasing: A sequence for high temporal resolution functional MRI.
PURPOSE In this work, we combine three-dimensional echo planar imaging (3D-EPI) with controlled aliasing to substantially increase temporal resolution in whole-brain functional MRI (fMRI) while minimizing geometry-factor (g-factor) losses. THEORY AND METHODS The study was performed on a 7 Tesla scanner equipped with a 32-channel receive coil. The proposed 3D-EPI-CAIPI sequence was evaluated f...
متن کاملRapid T(1) mapping using multislice echo planar imaging.
Determination of neurological pathology in white matter disease can be made in a semiquantitative way from T(1)- or T(2)-weighted images. A higher level of quantification based on measured T(1) or T(2) values has been either limited to specific regions of interest or to low-resolution maps. Higher-resolution T(1) maps have proved difficult to obtain due to the excessively long scan times requir...
