Specific T-weighted MRI sequences are able to detect SN neuromelanin (NM) signal changes and accurately discriminate Parkinson’s disease (PD) patients from controls. The study of NM-MRI in PD patients carrying a LRRK2 gene mutation (LRRK2-PD) could contribute to further uncover LRRK2-associated phenotype. Albeit considered to largely overlap idiopathic PD (iPD), differences have been described. Furthermore, the...
