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

Figure 6

The CEST signals measured at 3.0 ppm peaked at around 10 min after injection of the Glu alone solution with different doses (0.7, 1.4, 2.8, and 7.0 mmol/kg). These maximum CEST signals in the renal medulla increased in a dose-dependent manner and plateaued after 2.8 mmol/kg.
