Abstract
Techniques, systems and computer program products are disclosed for mapping of vascular perfusion territories by placing one or more blood vessels of the vascular perfusion territories in a tag condition and others in a control condition by applying a train of pseudo-continuous radio frequency tagging pulses. In addition, an encoding scheme is applied to fully invert or relax the blood vessels of the vascular perfusion territories. Also, a tagging efficiency is measured for each blood vessel based on the applied encoding scheme. Further, the vascular perfusion territories are separated by using the measured tagging efficiency in a decoding process.
