Presaturation Power Adjusted Pulsed CEST: A Method to Increase Independence of Target CEST Signals

Figure 1

The phantoms including nicotinamide (Nic), glutamate (Glu), creatine (Cre), and glucose (Glc) aqueous solution in low and high concentrations. A 1% agar phantom is also included as a control. The low and high concentrations for each substance are determined to show approximately 5% and 10% CEST signals at 3.5, 3.0, 2.0, and 1.0 ppm, respectively, in a condition of CEST imaging at 37°C.
