Diffusion Tensor Imaging (DTI) and Fractional Anisotropy (FA) for Arcuate Fasciculus in Predicting Post-Stroke Aphasia Outcome

چکیده

Background: In certain regions of the brain, aphasia arises from a lack understanding and regulating language following damage. About 35–40 percent people receiving hospitalization after stroke are identified with aphasia. The recently developed imaging methods for analysis impact brain lesion sites sizes on Diffusion Tensor Imaging (DTI) Fractional Anisotropy (FA). order to reflect micro-structural integrity DTI may give data damage level white matter subcortical neural structure. Objective: We examined relationship between arcuate fasciculus (AF) prognosis outcome ischemic utilizing DTI, FA. Patients Methods: this study, which included 34 patients post aphasia, we investigated FA in predicting post-stroke outcome. Results: There was no significant association sex Aphasia Handicap Scale (AHS) (P>0.05), while age significantly correlate AHS (P<0.05). vascular risk factors (hypertension, diabetes mellitus, smoking, dyslipidemia) were associated poor outcome. our found that size had effect Also, site infarction important factor determining Broca Wernicke regions, greater than cortical injury, insula injuries (1.92 ± 1.26) least common patients. Conclusion: predicted s outcome, also extent mechanism AF can be detected FA, stood as indicator severity stroke.

Prediction of aphasia outcome using diffusion tensor tractography for arcuate fasciculus in stroke.

BACKGROUND AND PURPOSE The AF is an important neural tract in language function. We investigated aphasia outcome according to DTT findings for AF in the early stage of stroke. MATERIALS AND METHODS Twenty-five consecutive patients with aphasia and stroke and 12 control subjects were recruited. The AQ of K-WAB was used for the assessment of aphasia in the early stage of stroke (10-30 days) and...

Diffusion tensor MRI tractography reveals increased fractional anisotropy (FA) in arcuate fasciculus following music-cued motor training

Auditory cues are frequently used to support movement learning and rehabilitation, but the neural basis of this behavioural effect is not yet clear. We investigated the microstructural neuroplasticity effects of adding musical cues to a motor learning task. We hypothesised that music-cued, left-handed motor training would increase fractional anisotropy (FA) in the contralateral arcuate fascicul...

Diffusion tensor spectroscopy and imaging of the arcuate fasciculus

The arcuate fasciculus (AF) is a fiber pathway in the human brain relevant for language processes and has recently been characterized by means of diffusion tensor tractography. The observations made concerning the left and right hemisphere AF include a characterization of the trajectories and quantification of physical properties such as fractional anisotropy, DTI-based fiber density and volume...

Diffusion Tensor Imaging Studies on Arcuate Fasciculus in Stroke Patients: A Review

Aphasia is one of the most common and devastating sequelae of stroke. The arcuate fasciculus (AF), an important neural tract for language function, connects Broca's and Wernicke's areas. In this review article, previous diffusion tensor imaging (DTI) studies on the AF in stroke patients were reviewed with regard to the usefulness for diagnosis (seven studies), prediction of prognosis (two studi...

Relation between aphasia and arcuate fasciculus in chronic stroke patients

BACKGROUND The role of the arcuate fasciculus (AF) in the dominant hemisphere in stroke patients with aphasia has not been clearly elucidated. We investigated the relation between language function and diffusion tensor tractography (DTT) findings for the left AF in chronic stroke patients with aphasia. METHOD Twenty five consecutive right-handed stroke patients with aphasia following lesions ...
