QuestionChoice
Given the patient's age group, presentation of sensory and motor loss, with previous episodes of unilateral painful vision loss, the most likely diagnosis is multiple sclerosis (MS). This refers to auto-inflammatory demyelination of neurones in the central nervous system. MRI is more suitable for scanning the central nervous system as it is sensitive to soft tissue changes. In an MRI, these appear as periventricular white matter lesions. With her presentation with 2 episodes, a finding of 2 or more lesions will lead to a diagnosis of MS

QuestionChoice
While this is sensitive to soft tissue and neurological problems, it is not the first line investigation used to diagnose MS. In MS, it will show increased activation of inflammatory cells in white matter and periventricular lesions.
