Název v původním jazyce

Assessment of the cerebral vasomotor reactivity in internal carotid artery occlusion using a transcranial Doppler sonography and functional MRI.

Popis výsledku v původním jazyce

Background and Purpose: Several methods are being used to assess cerebral vasomotor reactivity (CVR), including transcranial Doppler (TCD) sonography and blood oxygenation level-dependent functional magnetic resonance imaging (fMRI). The aim was to assess the correlation of TCD and fMRI in the CVR assessment. Methods: Study group consisted of 28 patients (24 males, 4 females; aged 30?82, mean 63.1 ? 10.0 years), presenting with 29 occluded internal carotid arteries. The TCD examination, including breath-holding/hyperventilation test (BH/HV) and breath-holding index (BHI), and fMRI examination were used for the assessment of CVR. fMRI employed a bimanual motor task within both a block paradigm and an event-related paradigm. Cohen?s ? was applied when statistically assessing correlation of the methods. Results: The following correlations were found?between BH/HV and BHI 58.6%, ? = .205; BH/HV and fMRI 65.5%, ? = .322; BHI and fMRI 58.6%, ? = .151; TCD (consistent result of both B
