Tract based measurements in post-connectometry analysis

[Sean Li]

Hello Dr. Yeh,

Thank you for creating DSI Studio, it is very easy to use. I have recently been using it to process DTI data for TBI patients. I am using the Correlational Tractography and the subsequent statistic/scatter plot functions. I have found some interesting data. I am able to extract mean FA, and MD values for each individual subject, but I wonder if it is also possible to also extract each patient's tract related measurements such as mean length and tract count?

Thank you,
Sean Li

For individuals, you may consider using differential tractography. Usually, we would report the volume of affected tract segments.

Best,

Frank

Dear Dr. Yeh,

Thank you for the extremely prompt response. How do you extract volume of affected tract segments for each individual? For my set of data, I only have a single time point, and if I understand differential tractography correctly, I would need longitudinal data to compute it. 

I appreciate your help,

Sean Li

Hello Dr. Yeh,

Thank you for the extremely prompt response. My patient data consists of a single data point. If I understand differential tractography correctly, it finds the neuronal change of a patient between two time points. If so, I don't think I would be able to use differential tractography to analyze my data. Do you know how else I could extract each patient's individual affected tract data and volume of affected tract segments?

Thank you,

Sean

There are different types of differential tractography, and you can compare one patient with a group of subjects.

You can also use the healthy subjects from the workshop course as the control pool for comparison.

Best

Hello Dr. Yeh,

Thank you for your response. I will look into this.
