Arterial spin labeling (ASL) provides a method for myocardial perfusion quantification without exogenous contrast agents. In MR-guided coronary catheterizations, perfusion measurements can provide a valuable tool to diagnose myocardial perfusion deficits and monitor the success of the intervention. In these interventions, catheters are usually visualized by active receive RF coils attached to the catheter. Using these active coils in transmit mode would enable intra-arterial spin labeling (iASL) in the coronary arteries with an increased labeling efficiency compared to conventional ASL. Here, we show the first in vivo results using iASL for myocardial perfusion measurements during coronary interventions in pigs.
