Simultaneous multislice (SMS) imaging is an attractive solution for accelerating MR acquisition due to its higher inherent SNR. However, further acceleration of SMS images along the phase encoding direction results in increased noise amplification. We demonstrate here the advantages of a combined virtual conjugate coil based phase-constrained SPIRiT reconstruction to minimize the g-factor penalty associated with highly accelerated SMS acquisitions.
