ABSTRACT:
An exemplary embodiment of system, method, and computer accessible medium for magnetic resonance spectroscopic imaging for improving signal-to-noise ratio per unit time and optimizing duty cycle in MRSI and/or for reducing chemical-shift artifacts can be provided. In one exemplary embodiment, an excitation pulse can be forwarded to the target and acquiring a signal from the target by multiplexing in time and space. The multiplexing procedure in time can involve (i) a segmentation of a field of view of the at least one portion of the target into a predetermined number of slabs that are acquired sequentially during each repetition time, and/or (ii) an acquisition of multiple voxels. Data can be generated based on the acquired signal. According to another exemplary embodiment, an excitation pulse can be provided to the target, and a signal can be acquired from the target. The excitation pulse can be a series of cascaded Hadamard pulse components. Data can be generated based on the acquired signal.
