A spectroscopic imaging technique was developed combining Sensitivity Encoding (SENSE) with Multi-Echo Correlated Spectroscopic Imaging (ME-COSI). In this initial application, parallel imaging acquisition was used to double the number of spatial points from 8x8 to 8x16 with a corresponding doubling of the effective Field-of-View (FOV). Testing in brain phantom demonstrated the presence of several expected diagonal and cross peak resonances throughout the excited volume including regions subject to residual folding artifacts. The sequence could be developed further, including accelerating acquisition by applying SENSE to both spatial dimensions. This sequence represents the first application of parallel imaging to correlated spectroscopic imaging.
