An investigation of sex-related differences in MRI-derived brain aging, highlighting the importance of subgroup-aware analyses.
Predicting Brain Age Using Machine Learning Algorithms: A Comprehensive Evaluation
A comparison of prediction algorithms supporting careful model selection rather than reliance on a single method.
The accuracy of T1-weighted voxel-wise and region-wise metrics for brain age estimation
Research on how imaging representations affect prediction performance and the choice of an analysis pipeline.
Patch-wise brain age longitudinal reliability
A study of repeatability over time, an important distinction from one-time prediction accuracy.
