1. Method for the MRT representation of a blood vessel (A) and/or the territories supplied by the blood vessel (A) by labelling the blood guided by blood vessel (A) by means of continuous arterial spin labelling in a specific labelling plane (E), with the steps of varying the position of the labelling plane (E), provided that a specific position of blood vessel (A) remains in labelling plane (E) choosing a labelling plane (E) inclined by an inclination angle θ of 1 to 60° to a predetermined longitudinal axis of blood vessel (A) and rotating the inclined labelling plane (E) about blood vessel (A) as the longitudinal axis.
