Summary
Advanced diffusion imaging techniques, like CSD, DSI, and DKI, offer superior insights into white matter integrity for post-stroke aphasia (PSA) recovery compared to conventional diffusion tensor imaging (DTI). These methods aid in personalized rehabilitation.
Area of Science:
- Neuroimaging
- Neurology
- Medical Physics
Background:
- Stroke is a primary cause of death and disability, with aphasia being a frequent and severe consequence.
- Diffusion imaging techniques assess white matter integrity and offer relevant measures for post-stroke aphasia (PSA).
Purpose of the Study:
- To review and synthesize studies using diffusion tensor imaging (DTI) or advanced diffusion imaging to explore structural connectivity in adults with PSA.
- To categorize studies based on their diagnostic, prognostic, or therapeutic applications in PSA.
Main Methods:
- A comprehensive literature search was performed across PubMed, CENTRAL, Ovid MEDLINE, and Embase.
- Ninety-five studies investigating structural connectivity in PSA using DTI or advanced diffusion models were included and synthesized.
Main Results:
- Most studies (n=77) used conventional DTI, while a smaller but growing number (n=18) employed advanced models like CSD, DSI, and DKI.
- Diagnostic, prognostic, and therapeutic applications were identified in 59, 17, and 19 studies, respectively.
- Diffusion-derived markers of language pathways and preserved global network architecture correlated with language performance and recovery.
Conclusions:
- Advanced diffusion imaging methods provide superior characterization of white matter architecture and clinical-anatomical correlations in PSA compared to conventional DTI.
- Markers from language pathways and network analyses are linked to language function and recovery.
- Translating diffusion imaging findings into clinical biomarkers for personalized aphasia rehabilitation requires further research, emphasizing advanced methods.
