Hybrid dynamic bright and black blood angiography by vessel-selective saturation angiography

Motivation: Examining a simultaneous bright and black blood sequence. Goal(s): Demonstrate ability to simultaneously acquire bright and black blood contrast in one image, providing simultaneous information on time-resolved artery-selective blood flow as well as the vessel walls integrity. Approach: Feasibility was evaluated by comparing calculated magnetization from a Bloch simulation and measured signal values from volunteer. Results: Simulated and measured image data showed a largely similar course over time points. An outlier time point has to be further investigated. Best black blood contrast to surrounding tissue was not found at the time point with the lowest blood signal. Impact: The study demonstrates the ability to simultaneously acquire bright and black blood contrast in a single image set and resulting simultaneous information on time-resolved artery-selective blood flow as well as the vessel walls integrity.
