Webhours for the processing of the whole brain data. As a result, this data processing is performed off-line, hampering the ability to ensure the quality of myelin water images during a scan session. In recent years, artificial neural networks (ANN) have been proposed as a promising tool to process complex biomedical data8. Webto generate an optimized myelin enhanced contrast image. The workflow allows whole brain mapping using the T1-w/T2-w technique, which was originally introduced as a non-invasive method for assessing cortical myelin content. The hallmark of our approach is a retrospective calibration algorithm, applied to bias-corrected T1-w and T2-w images,
