Performance of saturation recovery preparation for blood and myocardium vs off-resonance and transmitter B1 for varying [Gd]. Over the target design range of ±150 Hz and 17.5–29.6 μT (65–110% of effective FA) (dotted white box), the residual magnetization was < 0.5% in the myocardium for [Gd] up to 1 mmol/L, and for blood was < 0.5% up to 2.5 mmol/L, < 1% up to 5 mmol/L, and < 2.5% up to 10 mmol/L
