Stroke due to LVO is a true medical emergency in which the rapidity of diagnosis afforded by CTA is a strongly relevant clinical consideration. In patients with renal insufficiency or x-ray contrast Cerebrovascular Diseases-Stroke allergy, TOF MRA can be used to identify arterial occlusions without putting the patient at risk and inform subsequent therapeutic decisions [52]. MRA Neck Without and With IV Contrast Although sensitive and specific in the detection of extracranial vascular disease and delineation of anatomy, MRA of the neck may delay EVT in the setting of stroke due to LVO, which possibly detracts from the usefulness of this procedure due to the potential harm of delayed treatment [39,56]. Stroke due to LVO is a true medical emergency in which the rapidity of diagnosis afforded by CTA is a strongly relevant clinical consideration. In patients with renal insufficiency or x-ray contrast allergy, TOF MRA can be used to delineate arterial anatomy without putting the patient at risk and inform subsequent therapeutic decisions [52]. Current AHA guidelines recommend noninvasive imaging of the cervical carotid arteries for patients with TIA or minor stroke who are candidates for CEA or stenting, within 48 hours of onset [12].
