MRI mapping of brain iron deposition in patients with neurological diseases with a focus on multiple sclerosis and neuromyelitis optica
 Pudlač, Adam ; Burgetová, Andrea (advisor) ; Lisý, Jiří (referee) ; Ryška, Pavel (referee)
Background: Neuromyelitis optica (NMO) and multiple sclerosis (MS) often manifest similar symptoms. However, the distinction between the two diseases is particularly important for different therapies. The aim of this study is to determine whether these diseases can be distinguished based on cerebral iron deposits in the deep grey matter and whether there is a correlation between iron deposits, local deep grey matter atrophy and clinical severity of the disease. Methods: 40 patients with relapsing-remitting MS (RRMS), 20 patients with NMO and 20 healthy subjects were examined at the MRI department of the 1st Faculty of Medicine of Charles University in Prague from December 2013 to March 2015. All patients with RRMS fulfilled the revised McDonald criteria, the diagnosis of NMO was based on Wingerchuk criteria. All 20 patients with NMO had positive AQP4-IgG. Quantitative susceptibility mapping (QSM) and volumometry of individual deep gray matter structures were performed. All patients with NMO and MS underwent simultaneous examination by a specialist in demyelinating diseases. Neurological disability was assessed by the Kurtzke Disability Status Scale (EDSS). Results: Patients with NMO have higher magnetic susceptibility values in the substantia nigra compared to healthy controls. Patients with RRMS...
