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 principle...

Area of Science:

Medical Imaging
Neuroscience
Biomedical Engineering

Background:

Longitudinal analysis of Diffusion Tensor Imaging (DTI) aids disease monitoring.
Current methods often analyze scalar diffusion properties (e.g., Fractional Anisotropy), overlooking richer information in Apparent Diffusion Coefficient (ADC) images.

Purpose of the Study:

To present a general framework for detecting changes between two sets of ADC images.
To investigate the performance of four statistical tests for analyzing longitudinal DTI data.

Main Methods:

Development of a general framework for change detection in ADC image sets.
Evaluation of four statistical tests on simulated and real DTI data.
Application to the follow-up of multiple sclerosis lesion evolution.

Main Results:

The proposed framework enables analysis of richer information from ADC images.
Performance of different statistical tests was assessed for longitudinal DTI analysis.
Demonstrated utility in tracking changes in multiple sclerosis lesions over time.

Conclusions:

The presented framework offers a more comprehensive approach to analyzing longitudinal DTI data.
Statistical test performance varies, guiding selection for specific applications.
This method holds promise for improved disease monitoring and understanding neurodegenerative processes.
