Zero Echo Time (ZTE) imaging is a technique with clinical potential for imaging tissues with very short T2 relaxation times. Due to the presence of a gradient during RF excitation, there is a slice profile effect that creates artifacts in the reconstructed image. This can be corrected prior to image reconstruction, at the cost of image SNR. Increasing pulse duration increases the signal acquired while reducing it lessens this profile effect. Hence, there exists an optimal pulse duration that balances these sources of signal loss. Herein, we present an optimized approach to maximizing SNR in ZTE imaging.
