Synopsis

Keywords: MR-Guided Interventions, MR-Guided Interventions

Motivation: Dynamic intra-arterial spin labeling (iASL) has the potential to dynamically display flow in coronary arteries with high temporal resolution without contrast agents.

Goal(s): Investigate the feasibility of multi-bolus 2D and 3D dynamic iASL with different temporal resolutions and acquisition times.

Approach: The labeling and acquisition scheme is implemented in a FLASH sequence, and iASL measurements are acquired in a vessel phantom.

Results: 2D and 3D acquisitions are feasible with a potential optimization towards breath-hold acquisitions.

Impact: Dynamic iASL can visualize blood flow dynamics similar to contrast-enhanced fluoroscopy, making it an essential tool for MR guided catheterizations.
