Standardization of T1w/T2w Ratio Improves Detection of Tissue Damage in Multiple Sclerosis

Conclusion We have demonstrated the validity of standardizing the T1w/T2w ratio in an MS cohort. The sT1w/T2w ratio reduces CoV in NAWM of both MS patients and HC and was the only investigated measure to detect differences in NAWM in MS compared to HC. We propose that the sT1w/T2w ratio is a reliable and sensitive measure that can be used to investigate NAWM changes in MS.
