Use of a Simple Breath-Holding Task for Cerebrovascular Reactivity Scans in Clinical Functional MR Imaging
Functional MR imaging is a powerful tool for presurgical mapping of cerebral language and motor activity as a means of assessing and mitigating neurosurgical risk to eloquent cortex. Breath-hold scans allow radiologists to correctly interpret fMRI mapping studies by assessing cerebrovascular
reactivity and the detectability of cerebral blood oxygenation level dependent contrast on a regional basis. We present a simple and reproducible method for obtaining breath-hold scans and illustrate their clinical use in normal and pathologic conditions.
Keywords: BOLD = blood oxygenation level dependent; CVR = cerebrovascular reactivity; fMRI = functional magnetic resonance imaging; rCVR = relative cerebrovascular reactivity
