Abstract:
Objective To evaluate the role of three-dimensional multi-tissues (3DMT) CT reconstruction in imaging atlantoaxial and atlantooccipital deformities or traumas.Methods 10 normal volunteers and 42 patients with atlantoaxial and atlanoccipital deformities or traumas underwent spiral CT scan, then three-dimensional (surface shaded display, SSD) CT reconstruction and three-dimensional multi-tissues (3DMT) CT reconstruction.Results SSD and 3DMT reconstruction clearly demonstrated the anatomy of the bony structures and the spatial relationships between the occipitale and atlas, atlas and axis. 3DMT reconstruction respectively demonstrated the occipitale, atlas and axis. 3DMT more neatly demonstrated the deformities, fractures and dislocations of atlantoaxial and atlantooccipital joint than SSD reconstruction. Conclusion 3DMT CT illustrates the anatomical relationship of atlantooccipital and atlantoaxial complex and provides important information of the pathology. 3DMT is prior to SSD reconstruction.
