Abstract
A method for contrast-agent-free non-triggered angiographic imaging in magnetic resonance tomography that includes the steps of (S) 2D or 3D measurement of a bodily region having a flow of blood, using a flow-insensitive SSFP sequence, (S) measurement of the same bodily region using a flow-sensitive SSFP sequence, (S) registration of the measurement results obtained in steps Sand Sto one another, (S) unweighted or self-weighted subtraction of the registered measurement result obtained in step Sfrom the registered measurement result obtained in step S, (S) execution of a 2D or 3D image correction of the image obtained in step Sby removing image distortions caused by gradient field inhomogeneities and/or magnetic basic field inhomogeneities, and (S) representation of the angiogram obtained in step Sin the form of an MIP or segmented 2D or 3D vessel tree representation.
