PDFAbstract
Objective The purpose of this study is to explore the diagnostic accuracy of the fracture of optic canal using HRCT and 3D reconstruction. Methods 41 patients with fracture of optic canal were enrolled in our study and who have undergone routine CT, HRCT and 3D reconstruction. The point of the study is to analysis the diagnostic accuracy of the fracture of optic canal among the methods of routine CT, HRCT and 3D reconstruction. Results In all the patients, 11 cases (26.8%) were diagnosed the fracture of optic canal by using routine CT, 32 cases (78.0%) by HRCT and 39 cases (95.1%) by 3D reconstruction. There are significant differences between routine CT and HRCT ( P<0.05). However, HRCT is no significant difference 3D reconstruction for diagnosing the fracture of optic canal (P＞0.05). Conclusion HRCT and 3D reconstruction could significantly improve the diagnostic accuracy of the fracture of optic canal. Therefore, HRCT and 3D reconstruction may play a crucial role for diagnosing the fracture of optic canal.
