title: Thin-section definition in magnetic resonance imaging. Technical concepts and their implementation.
abstract: In multisection magnetic resonance imaging, gradient strength and earliest desired echo time (TE) set a limit to the thinnest section achievable. Offset radio-frequency irradiation techniques and phase encoding within a thick section make possible the production of thin sections of clinically useful quality in practical imaging times.
