Breath holding for 20 s following extended expiration is a practical, effective and robust standard when measuring cerebrovascular reactivity in healthy adults using BOLD fMRI at 3 T

Breath holding for 20 s following extended expiration is a practical, effective and robust standard when measuring cerebrovascular reactivity in healthy adults using BOLD fMRI at 3 T

Background and Purpose: BOLD fMRI is becoming the preferred modality to study cerebrovascular reactivity. Amongst the vasoactive stimuli to induce it, breath holding is considered equal to other methods but both cerebrovascular reserve measures and breath holding designs lack standardization. We hav...
