Study on sagittal diameter of cervical spinal canal and Pavlov index in radiographs and in MRI of 40 normals adults

ABSTRACT

Comparision diameter of the cervical spinal canal and calculate Pavloc index of 40 nomal adults aged 25 to 55 in standard lateral radiographs and MRI showed that The average indexs in MRIs are from C3 to C10 12,82 ±0,93mm and 0,95 ± 0,10. From C3 toC7 12,9 ± 0,91mm and 0,95 ± 0,10. From C1 to C7 13,6 ± 0,83mm and 1,25± 0,10, in radiographs are From C3 to C6 17,35 ± 1,12mm and 0,98 ±0,08. From C3 to C7 17,46 ±1,26mm and 0.98 ± 0,08. From C1 to C7 18,5 ±1,19mm and 1,26 ± 0,09. The pavlov index in MRI are smaller than that in standard lateral radiographs but they are not different significally
