Abstract
Magnetic resonance images (MRI) are generated by acquiring a plurality of N>2 image data sets for an imaged patient volume using respectively corresponding different data acquisition imaging parameters. At least one hybrid image data set X is generated for the imaged patient volume based on a combination of at least a subset of the plurality of image data sets. If desired, a further subtraction image (e.g., MRA) data set is generated based on a difference between the at least one hybrid image data set and another image data set, and the subtraction image data set, which may, depending upon implementation, optimize flowing fluids such as blood within arteries or veins, CSF, etc within the imaged patent volume, is output for storage or display as an MR image of the imaged patient volume.
Claims22
A method for generating a magnetic resonance image of fluid, said method comprising:
- using a magnetic resonance imaging (MRI) system gantry to acquire a plurality of N>2 image data sets for an imaged patient volume using respectively corresponding different data acquisition imaging parameters;
- using at least one programmed computer to:
- generate at least one hybrid image data set X for said imaged patient volume based on selective filling of a data set X pixel value at a particular location using pixel values at said particular location found in at least one of at least a subset of said plurality of image data sets;
- and
- output an image data set that is based on said hybrid image data set X for storage or display as an image of said imaged patient volume.
An MRI system configured to generate magnetic resonance images of fluid, said system comprising:
- means for acquiring a plurality of N>2 image data sets for an imaged patient volume using respectively corresponding different data acquisition imaging parameters;
- means for generating at least one hybrid image data set X for said imaged patient volume based on selective filling of a data set X pixel value at a particular location using pixel values at said particular location found in at least one of at least a subset of said plurality of image data sets;
- and
- means for outputting an image data set that is based on said hybrid image data set X for storage or display as an image of said imaged patient volume.
