The ratio of displaying the main trunk,
first branch (cervicofacial branches、temporofacial branches ) and secondary branch (temporal branches、zygomatic branches、buccal branches、marginal mandibular branches、cervical branches ) of facial nerve in parotid gland section was 100%、97.6%、51.4% with head coil combined with 3D-PSIF-DWI sequence, and 100%、100%、83.8% with micro surface coil. There was statistical significant difference(p <0.05) in the ratio of displaying the facial nerve secondary branches between two kinds of coils. The SIR (ratio of singnal intense) of facial nerve to parotid was 1.37±1.06 in the group with head coil combined with 3D-PSIF-DWI sequence,and the other was 1.89±0.87 .
There was statistical significant difference (p <0.05).
