Abstract
In a method for the implementation of a perfusion measurement with magnetic resonance imaging, image datasets of a region of an examination subject to be imaged and positioned in an imaging volume of a magnetic resonance apparatus are generated in a time sequence, positional changes of the region to be imaged that occur relative to the imaging volume during the time sequence are acquired, and a correction of influences of the positional changes on the image datasets ensues according to the acquired positional changes.
Claims13
A method for making a perfusion measurement by magnetic resonance imaging, comprising the steps of:
- positioning an examination subject in an imaging volume of a magnetic resonance apparatus and, using said magnetic resonance apparatus, generating image datasets of a region of said examination subject in a time sequence;
- identifying positional changes of said region which occur relative to said imaging volume during said time sequence;
- and
- correcting influences of said positional changes on said image datasets dependent on the identified positional changes.
