Magnetic resonance imaging characteristics of multiple sclerosis plaques imaged with two-dimensional and three-dimensional Fourier transform techniques at low and mid field strengths

Two-gradient-echo, two-dimensional, Fourier transform multisection imaging: comparison with spin-echo imaging

A multisection, two-dimensional, Fourier transform, double-gradient-echo magnetic resonance imaging sequence with partial flip-angle excitation and section doubling by radiofrequency encoding approximately doubles the signal-to-noise ratio obtainable from a conventional spin-echo sequence at low field strength, while maintaining essentially equivalent contrast.
