title: Pulsed magnetization transfer versus continuous wave irradiation for tissue contrast enhancement.
abstract: Pulsed magnetization transfer and continuous wave irradiation techniques are analyzed and compared for saturation efficiency and radio-frequency (RF) power requirements at 1.5 and 0.5 T. Binomial RF pulses transmitted on resonance are a more power-efficient method of exciting saturation transfer and are easily implemented with any pulse sequence. Binomial pulses selectively excite all short T2 species and behave as 0 degrees pulses for on-resonance, long T2 species.
