Top panel, An example of thick rim lesion (yellow rectangle): QSM (A1) and MWF (A2) in a patient with relapsing-remitting MS. The QSM and MWF values in the core and rim are as follows: −5.2827 ± 14.3945 ppb and 2.2262 ± 17.7374 ppb; 1.5204% ± 1.3975% and 4....

The QSM and MWF values in the core and rim are as follows: −5.2827 ± 14.3945 ppb and 2.2262 ± 17.7374 ppb; 1.5204% ± 1.3975% and 4.2542% ± 2.5327%. Bottom panel, An example of thin rim lesion (yellow rectangle): QSM (B1) and MWF (B2) in another patient with relapsing-remitting MS. The QSM and MWF values in the core and rim are as follows: −3.0355 ± 10.271 ppb and 0.9208 ± 13.5405 ppb; 7.4161% ± 1.5726% and 8.4678% ± 1.3358%. The hypointense appearance of a thick rim lesion on the MWF map is lower compared with the thin rim lesions. Y. Yao et al.
