| Abstract | Materials and Methods: Dynamic imaging of the first pass of a bolus of a paramagnetic contrast agent was performed using a 3T whole-body magnet and a T1-weighted fast field echo sequence. The input function was obtained from the internal carotid artery. An initial T1 measurement was performed in order to convert the MR signal to concentration of the contrast agent. Pixelwise and region of interest (ROI)based calculation of cerebral perfusion (CBF) was performed using Tikhonov’s procedure of deconvolution. Seven patients with acute optic neuritis and two patients with acute stroke were investigated. |
