Researchers have developed a novel deep learning framework that can estimate macromolecular pool fraction (MPF) from conventional clinical MRI scans. This method, which is guided by physics and uses self-supervision, does not require specialized quantitative scans. The framework embeds an analytical two-pool magnetization transfer signal model and was trained on a large dataset of 7,705 MRI sessions. Results showed consistent MPF values in white and gray matter across different protocols and vendors, with a significant reduction in MPF observed in lesions associated with demyelinating diseases.
