The multiple echo approach provided a satisfactory (48±7%) increase in signal-to-noise ratio with respect to conventional methods.
The multiple echo approach provided satisfactory vessel localization capacity by using asymmetric triangular phase masking and a 4-mm-thick mIP.
Water suppression was achieved by usage of the double pulsed field gradient spin echo approach.
Water suppression was achieved using the double pulsed field gradient spin echo approach.
Spin-echo images were employed as opposed to the faster gradient-echo, as spin-echo approaches are less prone to confounds from radiofrequency inhomogeneity in assessment of T1 changes than are gradient echoes.
The echoing approach, up a flight of uncarpeted stone steps past bare walls, is chill and uninviting.
In spite of the obvious differences among the numerical schemes adopted, the approach that we propose here and the ECHO-approach share the common feature of requiring a single (per cell) conversion from the conserved to the primitive variables.
Three-dimensional steady-state free precession (SSFP) techniques allow for a higher image quality and CNR (blood/myocardium) than 3D gradient recalled echo (GRE) approaches [71, 72].
Echo shifting approaches, PRESTO [18], [19], increase volume coverage efficiency in fMRI by taking advantage of TE delays to apply additional RF pulses, but are SNR limited and run into restrictions at higher magnetic fields when T2 and T2* become inherently short.
These recommendations echo the approaches of Perutz, Bohr, and their colleagues as they brought concepts of physical sciences and new computational technology to great advances in biology a half century ago.
Two countries separated by a common language, and etc. Cognisant of such transatlantic riptides, NBC will echo its approach to Premier League football and carry British match commentary.
