Abstract:
Objective To evaluate the diagnostic value of three-dimensional CT(3DCT)in atlantoaxial lesions.Methods The findings of 3DCT were analyzed and compared with conventional CT and radiography in 124 patients with atlantoaxial disease.Results 124 cases of atlantoaxial lesion included fracture in 42,atlantoaxial rotatory dislocation in 73,hypoplasia of the dens in 4,and congenital atlantoaxial deformity in 5.Among the 124 cases,89 cases were diagnosed by X-ray,109 cases by conventional CT,121 cases by MIP,122 cases by SSD,124 cases by MPR and VR.Conclusion 3DCT can find the slight rotatory dislocation,so it is the most effective means for the diagnosis of atlantoaxial rotatory dislocation.3D and MPR of spiral CT are useful in the diagnosis of atantoaxial fracture.Combining conventional CT and X-ray film with 3DCT can improve the acuracy of the diagnosis.
