The PW, PH, TSA and SSA of developed pathways were measured on the CT images and they were also measured on the real objects by caliper and goniometer, Analysis of variance demonstrated that the difference between the CT scans and real objects had no statistical significance （P〉0.05）, Moreover, the difference between pedicle axis and developed pathway also had no statistical significance （P〉0.05）, The data obtained from 3-D reconstruction of MSCT demonstrated that individualized standards, are not only accurate but also helpful for the successful placement ofpedicle screws.展开更多
