Receiver operating characteristic (ROC) curve analysis of MRI quantitative parameters (magnetization transfer ratio [MTR] and the T2-mapping value [ms]) for diagnosing and differentiating the severity of inflammation in the extraocular muscles of myasthenia gravis (MG) patients. (A) Diagnostic efficacy of combined MRI quantitative parameters (MTR and the T2-mapping value) in the extraocular muscles of MG patients. (B) Efficacy of combined MRI quantitative parameters (MTR and the T2-mapping value) in differentiating the severity of inflammation in the extraocular muscles of MG patients with ophthalmoparesis (MG-O) and without ophthalmoparesis (MG-N) (MG-O vs. MG-N groups). Blue line, MTR. Red line, T2-mapping value. Green line, combined MTR + T2-mapping value.
