Fabry disease (FD) is a rare X-linked multisystem lysosomal storage disease caused by partial or total deficiency of a-galactosidase A (GLA). A progressive involvement of the kidneys, heart, and brain arteries has been reported. Using the transcranial color-coded duplex Doppler (TCCD), we report the case of a Fabry disease (FD) patient with a reduc...

Severe intracranial atherosclerotic stenosis (SIAS) remains at risk of recurrent ischemic events despite intensive medical management. Exhausted cerebrovascular reserve seems to be associated with higher risk of recurrent stroke. We used whole brain MRI to estimate basal perfusion using dynamic susceptibility contrast and cerebrovascular reactivity...

The assessment of cerebrovascular reactivity (CVR) has shown promising results for its use in medical diagnosis and prognosis, especially in patients suffering from severe intracranial arterial stenosis. However, its quantification remains uncertain because of a large variability inherent in brain anatomy and in methodological settings. To overcome...

Cerebrovascular reactivity is impaired in patients suffering from obstructive sleep apnea syndrome (OSAS) as demonstrated by transcranial Doppler studies. We use magnetic resonance imaging techniques to investigate the anatomical distribution of cerebrovascular reactivity changes in patients with OSAS, as well as their evolution after therapeutic a...
