1. A method for acquiring a high-resolution magnetic resonance image dataset of at least one limited body region, having at least one anatomical structure therein, of a patient, comprising: operating a magnetic resonance scanner, while a patient is situated therein, to acquire an overview image dataset of the patient comprising image data representing at least one limited body region, comprising at least one anatomical structure, and said overview image also comprising at least one reference body region that is situated in the patient separately from said at least one limited body region; providing said overview image dataset to a computer and, in said computer, determining at least one item of position information of the at least one anatomical structure using the overview image dataset, said at least one item of position information designating at least one of an exact position of said at least one anatomical structure in the patient, and a relative position of said at least one anatomical structure with respect to said at least one reference body region; operating said magnetic resonance scanner to acquire a high-resolution magnetic resonance image dataset of said at least one limited body region during a recording window that is set dependent on said at least one item of position information; providing said high-resolution magnetic resonance image dataset to said computer and, in said computer, evaluating the high-resolution magnetic resonance image dataset to determine evaluated high-resolution image data therefrom; and making the evaluated high-resolution image data available in electronic form as a data file from said computer.
