Abstract
The neurovascular fingerprint of BOLD (blood oxygen level dependent) bSSFP (balanced steady-state free precession) is analyzed by Monte Carlo simulations for different vessel geometries and on a vectorized vessel data set of mouse parietal cortex. The results support that bSSFP yields vascular properties similar to those found with spin echo BOLD, a small intravascular signal contribution except for larger vessels, and a high selectivity to microvessels.
