From: Compressed sensing to accelerate magnetic resonance spectroscopic imaging: evaluation and application to 23Na-imaging of mouse hearts

Fig. 6

Representative in vivo CS three-fold accelerated cardiac MRSI. CS reconstructed prospectively under-sampled 23Na CSI (R = 3) of a murine heart in short-axis orientation (colour) overlaid onto a 1H anatomical image (black and white). The position of the surface coil is indicated. The concentration reference phantom (CR) has been omitted from the CSI data. The difference in Na concentration between the myocardium and blood pool is clearly reflected in the color-coded signal amplitudes of the 23Na image. Example phased spectra for the myocardium (*) and left ventricular blood (+) are shown on the right. Both spectra are plotted on the same scale
