Contrast changes in portal vein and bile duct between centric and linear k-space ordering on three-dimensional segmented true fast imaging with steady-state precession magnetic resonance imaging

Visualization of Cerebrospinal Fluid Motion in the Whole Brain Using Three-dimensional Dynamic Improved Motion-sensitized Driven-equilibrium Steady-state Free Precession

“…Because of the steady state, the signal intensities of linear ordering were higher than those of low-high ordering on MSGs-off. 11 Longer acquisition duration times increased the signal intensities of MSGs-on because they allowed rephasing of the spins. In the volunteer study, images with the shortest acquisition duration time were rated higher than those with the longer acquisition duration time, which is good agreement with the results of the flow phantom study.…”

Balanced Turbo Field Echo with Extended <i>k</i>-space Sampling: A Fast Technique for the Thoracic Ductography

“…In addition, the method for k -space ordering might have affected the imaging contrast for MRTD. Morita et al 11 compared the contrast of the several structures in the upper abdomen between centric and linear k -space ordering on 3D SSFP, and reported that the contrast for vessels and fat decreased on centric k -space ordering compared to linear k -space ordering, while that for the bile duct was not significantly different between these k -space ordering methods. Although we assumed that visualization of both the thoracic duct and surrounding structures has an advantage on balanced turbo field echo imaging, prominent visibility of the tissues around the thoracic duct might interfere the correct interpretation of the thoracic duct.…”
