Abstract:
Objective The three-dimensional reconstructed images of maximum intensity projection (MIP) for membranous labyrinth and internal auditory meatus in Chinese adults were observed and measured in order to provide anatomic basis for otolosurgery and nerosurgery. Methods Thirty inner ears of 15 volunteers were scanned by using a circular temporal coil and three-dimension fast spin echo sequence with a 1^5T GE-signal MRI scanner. All original images were transferred to MRI workstation and all the structures of inner ear were reconstructed, rotated from various angles and measured by using maximum intensity projection. All the data were analyzed using SPSS 10.0 software. Results Anatomic structures of membranous labyrinth and internal auditory meatus were well demonstrated in three-dimensional reconstructed images of MIP in all volunteers. All three semicircular ducts, utricle, saccule, cochlear duct and internal auditory meatus produced high intensity signal. The results of measurement were statistically in significant.Conclusion Three-dimensional reconstruction of MlP might document, lively, stereoscopically and directly, the minute structures of membranous labyrinth and internal auditory meatus. We provide the basic data for the establishment of the MRI measurement criterion of inner ear.
