Little is known about the clinical usefulness of diffusion tensor tractography (DTT) for the arcuate fasciculus (AF) in stroke patients with aphasia. Using DTT, we attempted to investigate the clinical usefulness of the AF in patients with aphasia. Five stroke patients and 7 age- and sex-matched normal subjects were recruited for this study. We recruited stroke patients with language dysfunction who had lesions in the left corona radiata and basal ganglia level. DTT for the AF was reconstructed… Expand
Relation between aphasia and arcuate fasciculus in chronic stroke patients
TLDR
According to the findings, the remaining volume of the left AF, irrespective of directionality and diffusivity, showed moderate positive correlation with language function in chronic stroke patients with aphasia. Expand
Injury of the Arcuate Fasciculus in a Patient with Progressive Bulbar Palsy: A Diffusion Tensor Tractography Study
TLDR
The injury of the left AF in this patient appeared to coincide with Broca’s aphasia, as demonstrated on diffusion tensor tractography (DTT), and is recommended for evaluation of the AF using DTT in patients with motor neuron disease who present with aphasIA. Expand
Excellent recovery of aphasia in a patient with complete injury of the arcuate fasciculus in the dominant hemisphere.
TLDR
The possibility that aphasia might show good recovery, even in cases of severe injury of the AF, is suggested. Expand
Recovery of aphasia and change of injured arcuate fasciculus in the dominant hemisphere in stroke patients.
TLDR
The results suggest that facilitation of the injured AF in the dominant hemisphere could be an important strategy in neuro-rehabilitation for stroke patients with aphasia. Expand

TLDR
Although scant studies on this topic have been conducted in stroke patients, DTI for the AF appears to provide useful information on the presence or severity of injury of the AF, prognosis prediction of aphasia, and recovery mechanisms of acersia in strokes patients. Expand

Prediction of Aphasia Outcome Using Diffusion Tensor Tractography for Arcuate Fasciculus in Stroke
TLDR
Evaluation of the left AF by using DTT in the early stage of stroke could be helpful in predicting aphasia outcome in patients with stroke. Expand
Reduced Diffusion Tensor Fractional Anisotropy in the Left Arcuate Fasciculus of Patients with Aphasia Caused by Acute Cerebral Infarct.
TLDR
The findings indicate that the left arcuate fasciculus is a crucial neural structure in aphasia, and that patients in the acute stage have not yet experienced the neural recovery that occurs in the chronic stage. Expand
Injury of the Arcuate Fasciculus in the Dominant Hemisphere in Patients With Mild Traumatic Brain Injury
TLDR
DTT could provide useful information in detecting injury of theAF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit. Expand
Correlation Between Speech Repetition Function and the Arcuate Fasciculus in the Dominant Hemisphere Detected by Diffusion Tensor Imaging Tractography in Stroke Patients with Aphasia
TLDR
It is found that unintegrated left arcuate fasciculus might be related to the repetition dysfunction after stroke, especially sentence repetition deficit, which suggests that sentence repetition evaluation could be used to indicate the integrity of the arcuate Fasciculus in the dominant hemisphere after stroke.

TLDR
Support is provided for a specific role for damage to the superior longitudinal and arcuate fasciculi in the left hemisphere in patients with deficits in repetition of speech in aphasia after stroke. Expand
The anatomical location of the arcuate fasciculus in the human brain: A diffusion tensor tractography study
TLDR
The detailed anatomy of the AF location in the human brain using diffusion tensor tractography is reported and it is believed that these results will be helpful to clinical neuroscientists for application in patients with aphasia. Expand
Corticospinal Tract Change in the Unaffected Hemisphere at the Early Stage of Intracerebral Hemorrhage: A Diffusion Tensor Tractography Study
TLDR
Investigation of changes in the corticospinal tract in the unaffected hemisphere at the early stage in patients with intracerebral hemorrhage, using diffusion tensor tractography (DTT), demonstrated that the CST in the affected hemisphere was changed at the late stage. Expand
The role of the arcuate fasciculus in conduction aphasia.
TLDR
Clinical and neurophysiological findings may suggest that the AF is not required for repetition although could have a subsidiary role in it. Expand

TLDR
The early DTT findings for CST may be used to predict the motor outcome of the affected extremities in hemiparetic patients with intracerebral hemorrhage and the statistical influence of the DTT type was tested. Expand

TLDR
TCF appears to represent a compensatory mechanism associated with motor weakness or CST injury in patients with ICH, and was found to be closely related to motor function reduction in affected extremities. Expand

TLDR
The findings of DTI tractography are combined with a recent model of brain language processing to explain 6 aphasia syndromes. Expand
Fiber density asymmetry of the arcuate fasciculus in relation to functional hemispheric language lateralization in both right- and left-handed healthy subjects: A combined fMRI and DTI study
TLDR
The findings suggest that the previously reported white matter asymmetry may be explained by a structural asymmetry in the arcuate fasciculus, which has important implications for the understanding of the functional and structural lateralization of brain regions as well as for the clinical evaluation of language function.

TLDR
This work demonstrated consistent connections between Broca's and Wernicke's areas along the superior longitudinal fasciculus bilaterally but more extensive fronto-temporal connectivity on the left than the right. Expand
