Microbleeds, lacunar infarcts, white matter lesions and cerebrovascular reactivity - A 7Â T study

► BOLD fMRI at 7 T can be used as a measure of cerebrovascular reactivity (CVR). ► CVR is lower in females, with increasing age, and lower diastolic blood pressure. ► Patients with microbleeds have impaired CVR. ► Lacunar infarcts and WML are not significantly associated with impaired CVR.
