Vital signs and noncontrast head CT were normal. To exclude AIS, we obtained an emergent gadolinium-enhanced MRI with diffusion-weighted imaging, PWI, and magnetic resonance angiogram (MRA) of the head and neck, 150 minutes after symptom onset (figure). The MRI did not demonstrate any area of reduced diffusion, vascular occlusion, abnormal arterial caliber, or dissection. Thrombolytic was not administered and the remaining magnetic resonance sequences revealed normal fluid-attenuated inversion recovery (FLAIR). After the MRI, … ER -
