Quantitative MRI (qMRI) may provide higher sensitivity to early pathological changes than standard qualitative assessment. This advantage, however, is yet to be rigorously compared with conventional diagnostic methods. This study aims to quantify the human ability to detect predefined changes in T2-weighted images as part of the diagnostic process of multiple sclerosis (MS). A visual diagnostic test was performed on neurosciences students, suggesting that the human vision has lower sensitivity to subtle MS lesions in T2-weighted images, in comparison to quantitative assessment of the change in T2 values.
