Hyperintensities on conventional MRI are not specific for demyelination, often causing diagnostic delay and sometimes misdiagnosis of patients with suspected Multiple Sclerosis (MS). In-vivo T2*-weighted MRI at 7T has been shown to depict central blood vessels within lesions at a much higher rate in patients with established MS compared with patients with microangiopathic white-matter (WM) brain lesions. In this work, we prospectively assess the predictive value of T2*-weighted imaging at 7T for an eventual diagnosis of MS in patients who were unable to be diagnosed by a Neurologist and Neuroradiologist without further paraclinical testing and clinical follow-up.
