Most
of the MR image accelerating methods suffer from degradation of acquired
images, which is often correlated with the degree of acceleration. However,
Wideband MRI is a novel technique that transcends such flaws. In this study
we demonstrate that Wideband MRI is capable of obtaining images with
identical quality as conventional MR images in terms of SNR, CNR
(contrast-to-noise ratio) and image sharpness, while using only half the
total scan time (Wideband factor W=2) of normal MRI sequence.
