Abstract
An MR image imaging procedure for the acquisition of the longitudinal spin-lattice relaxation time has a data-acquisition module with a slice-selective α-high-frequency impulse as well as magnetic gradients (G, G, G) for slice selection and/or for encoding of a k-space. The acquired data describes a time point of a spin-lattice relaxation and the data-acquisition module for acquiring data of a further time point being repeated. A 180° high-frequency impulse or a 180° high-frequency impulse and a 90° high-frequency impulse preceding the 180° high-frequency impulse generating a spin-lattice relaxation precede the data-acquisition module. The magnetic gradients Gand Gfor k-space encoding are simultaneously applied subsequent to the slice-selective α-high-frequency impulse. A temporal course of the magnetic gradients Gand Gis sinusoidal so that the result is a spiral coverage of the k-space and data are acquired during k-space encoding.
