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.
