Figure 3. Indirect 1H Spectroscopic and Imaging Detection Using INEPT Enhancement.

Figure 3

Single scan 1H detection of a 2.8 mL phantom of 4.3 M sodium 1-13C-acetate in water (a and b) without background multiband 1H suppression (Off) or INEPT enhancement (Off). Indirect 1H detection enhanced by INEPT for spectroscopy, and INEPT enhanced FSSFP for imaging for 2.8 mL phantoms of 4.3 M 13C-sodium acetate in water (c and d) and in D2O (e and f), and also 4.3 M natural abundance sodium acetate in D2O (g and h). A small amount of thermal naturally abundant acetate signal is detected even with background 1H suppression and can be observed in the inset of (g) and faintly in the image (h). All the images were acquired using TR = 6.20 ms, TE = 3.10 ms, FOV = 64×64 mm2, and an in-plane resolution of 2×2 mm2.
