Explanation:
Detailed explanation-1: -A computed tomography (CT) scan is not used to diagnose MS; although it can be helpful in ruling out alternative diagnoses. Overall, MRIs are significantly more sensitive in detecting abnormalities within the brain and spinal cord tissue.
Detailed explanation-2: -CT scans may be used to exclude other causes of neurologic impairment, but they have a low positive predictive value in the diagnosis of MS; thus, the false-negative rate is high.
Detailed explanation-3: -Other differential diagnoses of MS include central nervous system lymphoma, cysticercosis, metastatic tumors, migraine attacks with aura, multifocal gliomas, toxoplasmosis, and tuberculosis.
