Effect of dotarizine on CO2-dependent cerebrovascular reactivity

Acta Neurochirurgica, 1995
Dotarizine is chemically related to calcium antagonist cinnarizine and flunarizine. The study presented investigates the influence of the drug on the diameter of cortical arteries and cerebral blood velocity measured in the MCA in two groups of anaesthetized cats.

Transcranial Doppler cerebrovascular reactivity: Thresholds for clinical significance in cerebrovascular disease

Journal of Neuroimaging
AbstractBackground and PurposeThresholds for abnormal transcranial Doppler cerebrovascular reactivity (CVR) studies are poorly understood, especially for patients with cerebrovascular disease. Using a real‐world cohort with cerebral arterial stenosis, we sought to describe a clinically significant threshold for carbon dioxide reactivity (CO2R) and ...

Cerebrovascular reactivity in choroid plexus

ISMRM Annual Meeting
Motivation: Choroid plexus (CP) plays an important role in the production of CSF and the formation of the blood-CSF barrier, but its vascular function is unclear. Goal(s): We aim to quantify cerebrovascular reactivity (CVR) of CP in normal controls. Approach: We applied PCASL with 5%CO2 inhalation in 92 subjects and compared CVR in gray matter, white ...
