Hypothesized alterations in myelin and iron content in MS lesions associated with commonly observed R2*/QSM lesion contrast patterns
R2* Intensity | QSM Intensity | Alteration in Myelin Content | Alteration in Iron Content |
---|---|---|---|
Hypo | Hyper | ↓ | ↔ |
Hypo | Iso | ↓ | ↓ |
Iso | Hyper | ↓ | ↑ |
Note:—Hypo indicates hypointensity; Hyper, hyperintensity; Iso, isointensity; ↑, increase; ↓, decrease; ↔, little-to-no change.
