FIG. 6

The 4.7T MR images of a glucagon-treated fed mouse liver (bottom) and a control 24-hr fasted mouse liver (top) perfused with a 5 mM EuDOTAM-2M-2PB at 37°C. The “on-resonance” image (ωon = 42 ppm with duration of 2 s and B1 power level of 1 kHz) showed CEST contrast between the glucagon-treated perfused mouse liver and the liver without glucagon. The CEST image shows the intensity differences between the “off” and “on” images. Other imaging parameters included a [FOV] = 40 × 40 cm, 128 × 128 matrix, single 2 mm slice, TR = 4s,TE = 13 ms.
