The magnetic resonance imaging in multiple sclerosis consensus guidelines currently mandate three sagittal non-contrast enhanced sequences of T2-weighted fast spin echo, proton density-weighted fast spin echo and short tau inversion recovery; however, these particular three sequences have not previously been compared at 3T. This study compared T2-weighted fast spin echo, proton density-weighted fast spin echo, short tau inversion recovery as well as the double inversion recovery sequence for the sagittal detection of multiple sclerosis lesions in the cervical spinal cord at 3T. ⋯ This study provides the necessary evidentiary support at 3T for the magnetic resonance imaging in multiple sclerosis spinal magnetic resonance imaging protocol consensus guidelines. At 3T sagittal proton density-weighted fast spin echo and short tau inversion recovery sequences allowed improved detection of cervical spinal cord multiple sclerosis lesions, compared to T2-weighted fast spin echo and three-dimensional double inversion recovery magnetic resonance imaging. Utilising T2-weighted fast spin echo alone at 3T is insufficient for lesion detection.

Carotid web is thought to be a focal intimal variant of fibromuscular dysplasia, which comprises a high risk of stroke because of blood stasis and subsequent coagulative reactions that occur distal to the web. These lesions generally involve the posterolateral wall of the carotid and their developmental pathogenesis is controversial. ⋯ The carotid webs were projecting on the left posteriorly and on the right anteriorly into the inferior aspects of the bilateral proximal internal carotid arteries. The patient was started on clopidogrel and a high-intensity statin and remained on Plavix monotherapy for a 10-month follow up without a recurrent ischemic event.
