Assessment of Diffusion and Perfusion

Assessment of Diffusion and Perfusion

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

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.
