Measuring the transverse relaxation times (T2s) of metabolites from different regions of the brain provides important insight into different pathologies, but requires long acquisition. A novel k-space acquisition using a hybrid technique involving both echo planar spectroscopic imaging (EPSI) and concentrically circular echo planar trajectories (SI-CONCEPT) was applied to simulated brain tumor spectroscopic imaging data. In addition, an algorithm incorporating the backprojection information from the EPSI scan was developed to enhance the spectroscopic images. This novel acquisition and reconstruction technique, called SI-WEB, decreases the total duration of the scan while producing similar results when compared to the true T2 spectroscopic images.
