Magnetization transfer metrics in controls and in the different MS phenotypes studied
Controls | CIS | RRMS | SPMS | BMS | PPMS | |
---|---|---|---|---|---|---|
See the text for statistical analysis. | ||||||
CIS = clinically isolated syndrome; RRMS = relapsing-remitting MS; SPMS = secondary progressive MS; BMS = benign MS; PPMS = primary progressive MS; MTR = magnetization transfer ratio. | ||||||
