Description
Inclusion Criteria:
- Patients who are 18 years or older.
- Relapsing-remitting MS diagnosed as per Macdonald criteria
Exclusion Criteria:
- Contraindication to MRI. For example, metal implantation in the body, claustrophobia and pregnancy.
- Patients who are unable to tolerate the scans without moving the head as a result of symptoms such as tremor, spasticity, involuntary movements and spasms, cognitive impairment, coughing, and shortness of breath.

IVIM parameters (including ADC,D,D*,f) in Multiple Sclerosis brain regions.
Time Frame: Up to 2 months

Primary Outcome Measure: 1. IVIM parameters (including ADC,D,D*,f) in Multiple Sclerosis brain regions. The parameters are calculated based on a IVIM model bi-exponential model represented by: S(b)/S(0)=f ×exp(-bD*)+ (1-f)×exp(-bD), and the mono-exponential model for ADC calculation as represented by: S(b)/S(0)=exp(-bADC), where S(b) and S (0) are the MRI signal intensities at a given b value and b = 0, respectively. ADC: apparent diffusion coefficient. ADC is expressed in units of mm2/s. f: the perfusion or (micro) vascular volume fraction which depends on capillary geometry and blood velocity. f is expressed in units of mm2/s. D*: pseudo diffusion coefficient that resembles the perfusion related incoherent microcirculation. D* is expressed in units of mm2/s. D: pure diffusion coefficient which is related to pure molecular diffusion. D is expressed in units of mm2/s. |
