| 目的 探讨3D-CISS序列内耳及内听道成像技术及临床应用。方法 对30例共60只耳应用3D-CISS序列做颞骨容积扫描,采用多平面重建(MPR)及最大强度投影(MIP)行后处理,观察3D-CISS序列对内耳及内听道解剖结构及病变的显示。结果 3D-CISS序列扫描结合MPR及MIP重建对内耳迷路及内听道内神经及血管显示清晰,能够清晰显示病变与周围结构的关系,MPR重建对神经的显示优于MIP重建。结论 3D-CISS序列对内耳及内听道的结构及病变显示清晰,具有较高的临床应用价值。 |

| Purpose To study the technical and clinical application of MRI of inner ear and internal auditory canal (IAC) using 3D-CISS sequence. Methods Volume scans of temporal bone was performed in 30 patients (60 ears) using 3D-CISS sequence.Post-procession with multiplanar reconstruction (MPR) and maximum intensity projection (MIP) were operated to evaluate the ability of 3D-CISS sequence to show anatomic structures and lesions in inner ear and internal auditory canal. Results Scan combined with post-procession using 3D-CISS sequence could precisely show labyrinth,nerves and vessels in inner ear and internal auditory canal,as well as the relationship between lesions and structures around.As to the ability to evaluate nerves in IAC,MPR was superior to MIP. Conclusion 3D-CISS sequence can precisely show structures and lesions in inner ear and internal auditory canal,therefore it is of high value in clinical application. |
