A process for the contrast mediumfree angiographic imaging in the magnetic resonance tomography

摘要

A method for angiographic imaging contrast mediumfree not triggered in the magnetic resonance tomography,comprising the steps of:S1: 2d - or 3d - measurement of a blood - flow body portion having with a flow - insensitive ssfp - sequence,S2: measurement of the same body portion with a flux sensitive ssfp - sequence,S3: registering the in the steps s1 and s2 measurement results obtained with respect to each other,S4: not weighted or even weighted subtracting the obtained in step s2 registered measurement result of the registered measurement result obtained in step s1,S5: performing a 2d - or 3d - image correction of the image obtained in step s4 for the elimination of by means of gradient field - and / or magnet reason field - inhomogeneities image distortions caused,S6 of: representing the in step s5 angiogram obtained in the form of a mip - or a segmented 2d - or 3d - vessel tree representation.
