Increasing the perfusion signal to noise ratio (SNR) in velocity selective arterial spin labeling (VSASL) in magnetic resonance imaging

摘要

Techniques, systems computer program products are disclosed increasing tagging efficiency in velocity selective arterial spin labeling using multiple velocity selective saturation modules. In one aspect, a magnetic resonance imaging method for tagging arterial blood includes using two or more velocity selective saturation (VSS) modules to tag arterial blood. The tagged arterial blood is imaged.
