Walsh & Hoyt: Neuroimaging and Laboratory Findings

Neuroimaging techniques are crucial not only in the diagnosis of MS but also for determining prognosis for patients with MS and for patients with clinically isolated syndromes. This section focuses primarily on MR imaging; however, a brief description of CT scanning findings is also included because some patients with findings suspicious for MS may be unable to tolerate MR imaging because of claustrophobia or may be unable to undergo MR imaging for technical reasons (e.g., because of obesity or because they harbor metal implants or pacemakers).
