Retraction Note: Improved Sensitivity of Spin Echo and Parallel Acquisitions Using SENSE Compared to Gradient Echo Sequences in fMRI

Abstract

This work aims to validate the performance of spin echo and parallel acquisition using “SENSitivity Encoding (SENSE)” by comparing it to different imaging techniques, including gradient echo-planar imaging using parallel acquisition and SENSE usually used and gradient echo sequences and that of the echo of echo-planar spin. It compares the performance of sequences and their sensitivity to motor activity reflected by activation within the motor part of the brain. Image analysis of volunteers were processed individually. Image analysis techniques, such as normalization and smoothing, were used. Analyses were carried out using ‘Statistical Parametric Mapping’ operating under Matlab.
