The objective of this study was to discriminate signal changes of edema, encephalomalacia and excessive metal deposition in the lenticular nucleus of patients with Wilson’s Disease on quantitative susceptibility maps. Standard T1- weighted, T2- weighted, T2 FLAIR and QSM images were obtained on 14 WD subjects using 3T MRI. The results indicated that QSM could effectively discriminate different types of local lesions, including metal deposition hyperintensity, encephalomalacia hypointensity, and edema medium intensity. Furthermore, our study revealed that UWDRS and neurological symptoms scores of patients with severe abnormal MRI manifestations were significantly higher than that of patients with mild abnormal MRI.
