FIG. 2.
Static 31P-MRSI on a phantom. a: 1H structural images. b–d: Maps of Pi obtained by the conventional CSI (10 × 10 × 10 spatial encodings and six averages), EPSI (50 × 50 × 20 spatial encodings and six averages), and the proposed method (50 × 50 × 20 spatial encodings), respectively, in an equivalent-time acquisition experiment. e–g: Representative spectra from (b–d). The location of the spectrum is indicated by the red arrow in (a). Note that images from three representative slices are shown in (a–d). Please see Supporting Figure S1 for images from all the slices.
