METHOD AND APPARATUS FOR MOVEMENT CORRECTION IN A MAGNETIC RESONANCE FINGERPRINTING EXAMINATION OF A SUBJECT

摘要

In a method and apparatus for movement correction for a magnetic resonance fingerprinting examination on an object under examination, a magnetic resonance signal shape of a region of the object is acquired using the magnetic resonance fingerprinting method, movement data for at least one sub-region of the region are detected movement information is generated from the acquired movement data, the acquired magnetic resonance signal shape is corrected with reference to the generated movement information, a signal comparison of the corrected magnetic resonance signal shape is made with multiple database signal shapes stored in a database, with a database value of at least one tissue parameter being assigned to each of the database signal shapes. A value of the at least one tissue parameter is assigned to the corrected signal shape as a result of the signal comparison.

1. A method for movement correction in a magnetic resonance fingerprinting examination of an object, comprising:
operating a magnetic resonance scanner, while an object is situated therein, to execute a magnetic resonance fingerprinting method wherein a magnetic resonance signal shape of a region of the object is acquired; detecting movement data for at least one sub-region of said region; in a computer, generating movement information for said at least one sub-region from the detected movement data; in said computer, correcting the acquired magnetic resonance signal shape dependent on the generated movement information; in said computer, comparing the corrected magnetic resonance signal shape with multiple database signal shapes accessed from a database, with each of said multiple database signal shape having a value of at least one tissue parameter assigned thereto in said database; and dependent on said comparison, assigning a value of at least one tissue parameter to the corrected signal shape, and generating and emitting an electronic signal from said computer that designates said value of said at least one tissue parameter determined from said comparison.
