Predicting Quantitative Myelin Images from Clinical Scans and DTI using Linear and Neural Network Models

Key Points

A linear model predicts macromolecular pool-size-ratio maps effectively from clinical scans and DTI, enhancing diagnostic capabilities for multiple sclerosis.
Prediction results indicate that most relationships between clinical scans, DTI, and PSR maps are captured by a simple linear model with minimal increments from nonlinear methods.
The study compares the efficiency of linear and neural network models in predicting quantitative myelin images, revealing minimal advantage of complexity.
Leveraging standard clinical scans with linear models may significantly improve diagnostic outcomes, reducing reliance on more complex methods.

Abstract

Motivation: Quantitative myelin imaging methods are usually not included in clinical MRI scans for persons with multiple sclerosis. Goal(s): Predict macromolecular pool-size-ratio maps from standard clinical scans. Approach: Compare PSR map prediction results from linear model and neural network model. Results: Most of the relationship between clinical scans plus DTI and PSR maps is captured by a simple linear model and the more complex nonlinear model offers minimal improvements. Impact: Leveraging typical clinical scans to predict PSR maps using a simple linear model can improve diagnostic capabilities for multiple.
