Abstract Objective: To evaluate the diagnostic value of CUBE 3D T2WI fat suppression sequence in traumatic optic nerve injury. Methods: Twenty patients with orbital trauma were enrolled in this study. MR examination of STIR sequence and CUBE 3D T2WI fat suppression sequence was performed, which can get the imaging of optic nerve and optic chiasma. And then imaging were analyzed. According to the optic nerve segment of the signal with or without abnormalities and abnormalities degree of the signal(abnormal, suspicious anomalies, normal) for analysis and evaluation. Imaging results and clinical ophthalmic examination results were compared. Results: On the STIR sequences abnormal optic nerve injury was 50.0%(10/20), suspicious anomalies 20.0%(4/20), normal 30.0%(6/20); on 3D CUBE sequence, abnormal optic nerve disease was 55.0%(11/20), suspicious anomalies 30.0%(6/20), normal 15.0%(3/20). Conclusion: The CUBE 3D T2WI fat suppression sequence was significantly higher than the orbital conventional STIR scan sequence.
