Abstract
In this study a fully adiabatic volume selection sequence (LASER) with SPIRAL readout was developed to acquire high resolution (zoomed) T2 weighted images with reduced acquisition time. Thus, high temporal resolution combined with high spatial resolution was achieved. When adiabatic full passage pulses were inserted prior to the LASER localization to generate Carr-Purcell pulse train (CP-LASER sequence), this allowed detection of the images with different inter pulse delays at the same echo time. Here we demonstrate how the CP-LASER-SPIRAL sequence can be implemented for the fast MRI, and the application to functional MRI is presented.
