Abstract:Objective To establish normal data of lumbar spine of adult Guizhou miniature pig. Methods Ten healthy adult Guizhou miniature pigs (5 males, 5 females) were tested by measuring the diameters of the lumbar spine in this study. The miniature pigs were scanned by SIEMENS dual source computed tomography (CT) scanner, and the raw data were conducted for multiplanar reconstruction using Aquarius iNtuition 4.4. The transverse and longitudinal diameters of vertebral body and spinal canal, the widths of pedicle and osseous channel were measured at the median transverse plane of the vertebral bodies. The heights of vertebral body and pedicle were measured at the maximum sagittal section. The correlations between the width of the pedicle, osseous channel and the weight of miniature pig were analyzed. Results From lumbar 1 to 5, the transverse diameter of vertebral body and spinal canal increased gradually. No significant difference was found in the longitudinal diameter, spinal canal, width and height of vertebral body. The widest (9.81 mm±0.65 mm) and highest (17.77 mm±0.46 mm) pedicle was lumbar 3. A positively significant correlation was found between the width of pedicle and the weight of miniature pig (rL1=0.96, rL2=0.97, rL3=0.86, rL4=0.73, rL5=0.85; P<0.05), as well as between the osseous channel and the weight of miniature pig (rL1=0.97, rL2=0.90, rL3=0.89, rL4=0.52, rL5=0.65; P<0.05). Conclusions Multislice spiral CT and its post-processing software can accurately measure various data of the lumbar spine of Guizhou miniature pig in vivo, and therefore provide normal reference for setting up lumbar pathological model.
