Perfusion MRI of the human brain with dynamic susceptibility contrast: Gradient-echo versus spin-echo
spectrometers have the distinguishing characteristic
MR images of the pelvis obtained with a phased-array coil: value in localizing and staging prostatic carcinoma.
All three groups were subject to the same T2-weighted, fast spin-echo
and MRI in the axial and sagittal planes.
2] of 1 ms and a spin-echo
measurement of 160 points (0.
The measured quantity in neutron spin-echo
is related to the polarization of the scattered beam.
The other basic modification to the spin-echo
sequence that can be made is to acquire multiple lines of k-space during the TE interval.
Axial, proton density-weighted, fat suppressed, turbo spin-echo
(repetition time msec/echo time, 2500/13; turbo factor (TF) 5), 4-mm section thickness, 1-mm spacing, 512x256 matrix, NEX 1, FOV 14 cm.
The papers discuss transient oscillations in high-resolution solid state NMR (nuclear magnetic resonance) spectroscopy, application of high resolution magic angle spinning NMR spectrometry to define the cellular up-take of endogenous and exogenous molecules, magnetization transfer by cross polarization in liquid state NMR spectroscopy, spin-echo
in modulated gradient fro the spectral analysis of molecular motion, current developments in longitudinally detected electron spin resonance spectrometer for in vivo applications, probing the lung microstructure with diffusion- sensitive helium-3 imaging, examining amide proton relaxation rates of highly deuterated proteins, NMR studies of columnar liquid crystals, and high-resolution MR spectroscopy via adaptive sub-band decomposition.
Diffusion-weighted (DW) MRI scans were carried out on a 3T scanner using a radial fast spin-echo
Sialolithiasis and salivary ductal stenosis: Diagnostic accuracy of MR sialography with a three-dimensional extended-phase conjugate-symmetry rapid spin-echo
The result is that the locus of constant spin-echo
phase is Q-dependent.
