Objective:To explore the application value of multi-slice CT (MSCT) different measuring methods in the measure-ment of C2 cervical vertebral pedicle. Methods:51 patients suspected or confirmed upper cervical disease were collected and performed cervical CTA examination,all the primary data. Multi-planar reformation (MPR),maximum intensity projection (MIP) and volume render (VR)were used to show the structure of vertebra,vertebrae pedicle,the relationship between the cervical vertebra and adjacent structure. Measure the pedicle data of C2 in MPR,MIP and VR images,including pedicle width (PW), pedicle length (PL),pedicle height (PH),pedicle superior angle (PSA),pedicle median angle (PMA). Comparative analysis about the data difference,the operability and the display ability of post-processing image were accomplished by one technician in charge independently. Pair sample t-test statistical analysis was used for the difference of two sides and the consistency of C2 data of three methods. Results:MPR,MIP and VR could show the anatomy structure and nearby space relationship of cervi-cal pedicle vertebral. The records of pedicle were as follow:(1)MPR:C2-PW(R/L) (5.43±1.62)mm/(5.43±1.53)mm,C2-PL(R/L) (25.66±3.79)mm/(26.57±3.76)mm,C2-PH(R/L) (9.18±2.20)mm/(9.08±2.34)mm,C2-PSA(R/L) (31.79°±9.57°)/(32.13°±9.96°), C2-PMA(R/L) (31.14°±10.22°)/(32.69°±10.57°). (2)MIP:C2-PW(R/L) (6.04±1.62)mm/(6.11±1.66)mm,C2-PL(R/L) (28.59± 3.76)mm/(28.95±3.79)mm,C2-PH(R/L) (9.52±2.13)mm/(9.19±2.10)mm,C2-PSA(R/L) (28.73°±11.00°)/(29.88°± 2.82°),C2-PMA(R/L) (35.78°±11.84°)/(35.68°±12.30°). (3)VR:C2-PW(R/L) (6.82±1.75)mm/(6.52±1.92)mm,C2-PL(R/L) (28.28±3.93)mm/(28.40±3.76)mm,C2-PH(R/L) (9.64±1.73)mm/(9.33±2.13)mm,C2-PSA(R/L) (31.82°±8.81°)/(29.12°± 2.33°),C2-PMA(R/L) (34.00°±11.28°)/(36.43°±11.90°). With pair sample t-test statistical analysis,there was no significant difference between the left and right pedicle. Most of data had significant deviation ,which means there was significant differ-ence between three methods. MPR and MIP had advantage in operability and display ability of post-processing image,compared with VR. Conclusion:Three methods which can be used for the measurement of cervical vertebral pedicle and an accurate ref-erence for clinical screw placement,had provincial difference in pedicle data,operability and display ability of post-processing image. Different methods can be selected according to actual needs in clinic work.
