ABSTRACT:
In a magnetic resonance imaging method and apparatus, a double echo sequence having a gradient echo and a spin echo is implemented with a flow compensation for the gradient echo in at least one direction. The flow compensation gives the double echo sequence an insensitivity to flow phenomena.
