A Novel Grading System for Autism Severity Level Using Task-Based Functional MRI: A Response to Speech Study
2021
IEEE Access
Preserved Fulltext
Task-based fMRI is a discriminating image modality that measures the functional activation of the brain. ...
Here, we propose a novel computer-aided grading framework in infants and toddlers (between 12 and 40 months) dependent on the analysis of brain activation in response to a speech experiment. ...
The proposed framework block diagram of using task-based fMRI images for grading autistic subjects into three severity levels. ...
