Susceptibility weighted imaging: Clinical applications and future directions

Figure 19 Example quantitative susceptibility mapping image of a 55-year-old female relapsing-remitting MS patient, shows hyperintense susceptibility MS lesions, and the corresponding FLAIR, T1 and R2* images. Multiple contrast analysis using R2* and QSM may be helpful identifying different pathological changes in MS lesions. Gray scale is [-0.12, 0.12] ppm in QSM image and [0, 80] Hz in R2* image. MS data was acquired using similar 7T protocol as the HD study. QSM: Quantitative susceptibility mapping.
