Abstract
Method for susceptibility weighted magnetic resonance imaging of vasculature, the method comprising the following steps: —acquiring multi-echo data containing a time-of-flight signal in at least the first echo (S1); —identifying voxels belonging to arteries from the data (S2); and —generating corresponding information on artery presence (S3); The invention further relates to a corresponding system (10) for susceptibility weighted magnetic resonance imaging of vasculature.
Claims13
A method for susceptibility weighted magnetic resonance imaging of vasculature, the method comprising:
- acquiring multi-echo data containing a time-of-flight signal in at least the first echo;
- identifying voxels belonging to arteries from the data;
- and
- generating corresponding information on artery presence;
- wherein the method further comprises an echo combination step or an echo combination step in combination with a phase masking step;
- and
- wherein said information on artery presence is used to put emphasis on an artery appearance during said echo combination and/or to prevent an inclusion of voxels belonging to arteries in the phase masking step.
A computer program product for executing a method comprising:
- identifying voxels belonging to arteries from multi-echo data containing a time-of-flight signal in at least the first echo;
- and
- generating corresponding information on artery presence;
- wherein the method further comprises an echo combination step or an echo combination step in combination with a phase masking step;
- and wherein said information on artery presence is used to put emphasis on an artery appearance during said echo combination and/or to prevent an inclusion of voxels belonging to arteries in the phase masking step.
A system for susceptibility weighted magnetic resonance imaging of vasculature, the system comprising:
- a magnetic resonance device comprising:
- a pulse generator module configured to generate an excitation signal;
- and
- a data acquirer module, communicatively coupled with the pulse generator module and configured to acquire multi-echo data containing a time-of-flight signal in at least the first echo;
- and
- a post-processor module, communicatively coupled with the magnetic resonance device and configured:
- to post-process the data including an echo combination step and/or a phase masking step,
- to identify voxels belonging to arteries from the data;
- and
- to generate corresponding information on artery presence, wherein said information on artery presence is used to guide the echo combination and/or phase masking step.
