From: Morphology analysis of the C2 pediculoisthmic component and feasibility of safe C2 pedicle screw placement: comparison of multiplanar reconstruction versus traditional radiographic methods

Fig. 1

a The diameter of the endosteal cavity (TPW1) and outer diameter (TPW2) were measured perpendicular to the pedicle axis on the orthogonal axial plane. b Isthmus height and internal height were measured on an orthogonal sagittal image 3 mm lateral to the cortical margin of the spinal canal wall at C2. c and d The “MPR” operation in the software's toolbar was performed. The pedicle axis was determined by manipulating the sagittal multiplanar reconstructions. The width of the endosteal cavity (OPW1) and outer diameter (OPW2) were measured at the cross-sectional slices parallel to the sagittal pedicle axis
