System and methods for active suppression of superior tagging in flow-sensitive alternating inversion recovery
First Claim
1. A method for active suppression of labeled venous blood signals in magnetic resonance imaging, the method comprising:
- performing a labeling experiment;
capturing a first image of a slice of body tissue;
performing a control experiment;
capturing a second image of the slice of body tissue;
performing a ninety (90) degree RF saturation pulse directed to a portion of body tissue that is superior to one of the first slices of body tissue imaged during at least one of the labeling experiment and the control experiment; and
applying a spoiler gradient subsequent to the saturation pulse during at least one of the labeling experiment and the control experiment.

Abstract
Apparatuses, systems, and methods for suppression of venous artifacts from superior tagging in flow-sensitive alternating inversion recovery. The systems may include an image capture device and a controller. The controller may be configured to cause the image capture device to perform a labeling experiment, capture a first image of a slice of body tissue, perform a control experiment, and capture a second image of the slice of body tissue. The systems may be configured to perform a ninety (90) degree RF saturation pulse directed to a portion of body tissue that is superior to the first slice of body tissue imaged during at least one of the labeling experiment and/or the control experiment, and to apply a spoiler gradient subsequent to the saturation pulse during at least one of the labeling experiment and/or the control experiment.
