An imaging sequence often involves a series of excitation pulses to generate signals to cover k−space. Since a π/2−pulse completely rotates any available Mz component onto the transverse plane, magnetization along the z−axis is always zero immediately after a π/2−pulse in any imaging sequence with π/2−pulses. True or false??
