Men and women will be included. 5)
Exclusion criteria
Exclusion criteria: Exclusion criteria is shown below; 1) Patients or HCs who cannot take MRI due to the pacemaker, pregnancy, claustrophobia, and active asthma. 2) Patients of HCs who showed allergy for the contrast medium. 3) Patients or HCs with renal impairment: eGFR less than 30mL/min/1.73m2 for patients, eGFR less than 60mL/min/1.73m2 for HCs. 4) Patients or HCs who are considered as inappropriate by investigators. 5) HCs who are considered to have increased intracranial pressure and the possibility to cause the brain herniation by lumber tap. 6) HCs who have neurological disease, hematologic disease, renal desease, endocrine disease, lung disease, gastrointestinal disease, liver disease, mental disease, or the past history of the mental disorder. 7) HCs who have the past history of severe trauma of the brain or spine, or the past history of the gastrointestinal bleeding, urinary tract bleeding, or major surgery within 3 months. 8) HCs who are considered as inappropriate by investigators from the point of view of the tests including blood test or blood pressure. 9) HCs who took part in the clinical trial for the new drug within 4 months or took part in other clinical trials and received drugs within 3 months. 10) HCs who take the regular medicine including over-the-counter drugs. 11) HCs who are considered as inappropriate by investigators from the medical judgement.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Correlation between Ki (calculated by MRI) and Quotient albumin (showing the blood barrier breakdown and calculated by lumber tap) in the three groups (MS, NMOSD, HCs). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Correlation between Ki and white blood cell in the cerebrospinal fluid (CSF), serum and CSF cytokines, or myelin mapping in the three groups (MS, NMOSD, HCs). 2. Comparing these data between disease group (MS and NMOSD) and HCs. | — |
