Recently, there has been a growing interest in ultra-fast fMRI mapping. We are providing an optimized pulse sequence method for a 2D line-scanning technique, allowing for the detection of dynamic MRI signals with a high temporal resolution (6 ms). This work addresses an intriguing observation using MRI to directly detect neuronal activity in the brain; a topic that has been investigated by many scientists in the past few decades. This FLASH-based fMRI pulse sequence enables the ultrafast sampling of signals by reshuffling single k-space line acquisitions across multiple repetitions as a function of time for a given block design stimulation paradigm.
