The acquisition of a complete 2D MRSI data set is very time consuming, which is often unacceptable for clinical studies. Various approaches have been proposed for reducing the scanning time. In some situations, when not interested in signal from the entire object, one may consider using the reducing FOV approach. However, this method often suffers from aliasing. Alternatively, one can use the sequential forward array selection (SFAS) method for reducing the scanning time. In this work, we demonstrate that online SFAS not only provides high resolution MRSI with less data acquisition time, but also eliminates the aliasing unsaturated signal.
