This work investigates the microvascular specificity of
T1
ρ
functional
magnetic resonance imaging at very low locking fields.
Compared to conventional spin and gradient echo, we find
that relative to the tissue BOLD contrast, BOLD signal
in large vessels is better suppressed with T1
ρ
functional
imaging.
