Abstract:
1. A method of acquiring an MR image using an imaging procedure for the acquisition of the longitudinal spin-lattice relaxation time (T 1 ), with at least one data-acquisition module comprising at least one slice-selective α-high-frequency impulse as well as magnetic gradients (G x , G y , G z ) for slice selection and/or for encoding of a k-space, the acquired data describing a time point of a spin-lattice relaxation and the data-acquisition module for acquiring data of at least one further time point being repeated, wherein furthermore at least one 180° high-frequency impulse or at least one 180° high-frequency impulse and at least one 90° high-frequency impulse preceding the 180° high-frequency impulse for the generation of a spin-lattice relaxation precede the data-acquisition module, wherein the magnetic gradients G x and G y for k-space encoding are simultaneously applied subsequent to the slice-selective α-high-frequency impulse, a temporal course of the magnetic gradients G x and G y being sinusoidal, so that the result is a spiral coverage of the k-space; and wherein, furthermore, data are acquired during k-space encoding and generating a T1-weighted image using the acquired data.
