Figure 7.

Subsecond single-average nonslice-selective 2D MRI of 150 mM HP propane-d₆ (∼2 mL volume) at 0.0475 T with 0.88 × 0.88 mm² spatial and ∼0.7 s temporal resolution with 28 × 28 mm² field of view. The same batch of HP propane was used for subsequent 2D MRI scans every 3 s. Note that propane-d₆ images are more intense in the center due to greater sample depth in the center of the phantom variable cylindrical shape. The image on the right shows the corresponding 2D image (8 averages) of 55 M thermally polarized water (∼2.8 mL volume).
