title: The value of spatial reconstructions with computed tomography (3D CT) in recognising the fissure of vertebral arch.
abstract: The aim of the study is to assess the value of spatial reconstructions with computed tomography (3D CT) in recognising vertebral arch fissure. The material comprises 20 patients in whom 3D CT revealed vertebral arch fissure. Spatial reconstructions at bone threshold were done from computer data of axial sections. 3D CT was assessed in real time in optional projections and lightened at a selected angle. It was found that the most favourable projections for the assessment of vertebral arch fissure are lateral and antero-oblique ones performed from the inside of the vertebral canal after cutting off part of the reconstructed picture along spinous processes. In patients with degree I slip 3D CT in recognising arch fissure is a technique of choice.
