Popis:	We carried out magnetic resonance imaging (MRJ) in 3 cases of Bell's palsy. Case 1 was a 43 y. o. male, case 2 was a 21 y. o. female and case 3 was a 64 y. o. male. The diagnosis was in complete: Bell's palsy. Tl-weighted images (TR500/TE25-33) were taken before and after the intravenous administration of Gd-DTPA (0.1mmol/kg) using 0.5 Tesla superconductive type MRI 3, 8, and 11 days respectively after the onset. In the ipsilateral intratemporal facial nerve, enhancement of signalintensity was seen in the geniculate ganglion in casel, in the mastoid portion in case 2, and in the labyrinthine portion and geniculate ganglion in case 3. The possibility of imaging the facial nerve in Bell's palsy was demonstrated, and the diagnostic significance of Gd-enhanced MRI was discussed in this preliminary investigation.
