This study aims to determine the normal limits of atlanto-dental interval (ADI), basion-dens interval (BDI), basion-cartilaginous dens interval (BCDI), and prevertebral soft tissue thickness (PVSTT) according to age groups for normal pediatric cases.
CT images of 256 pediatric patients aged between 1 and 15 years were retrospectively evaluated. ADI, BDI, BCDI and PVSTT measurements were performed.
Upper normal limit (UNL) values for ADI were 2.65-4.8 mm. UNL values for PVSTT were found to be 6.9 mm at C1 level, 6.7 mm at C2 level, 9.3 mm at C3 level, 14.2 mm at C4 level, 14.1 mm at C5 level, 13.8 mm at C6 level and 12.8 mm at C7 level. The maximum value of BDI in the group with non-ossified os terminale was 12 mm, and in the group with ossified os terminale it was 10 mm. The UNL of BCDI determined for females was 5.1 mm, while the UNL for males was 5.6 mm.
We propose the obtained values as the UNL values for ADI, BDI, BCDI and PVSTT on CT images in the pediatric population from 1 to 15 years.
本研究旨在确定正常儿童病例中寰齿间隙（ADI）、颅底-齿突间隙（BDI）、颅底-软骨性齿突间隙（BCDI）和椎前软组织厚度（PVSTT）根据年龄组划分的正常范围。
回顾性评估了256例年龄在1至15岁之间的儿科患者的CT图像。进行了ADI、BDI、BCDI和PVSTT测量。
ADI的正常上限（UNL）值为2.65 - 4.8毫米。PVSTT在C1水平的UNL值为6.9毫米，C2水平为6.7毫米，C3水平为9.3毫米，C4水平为14.2毫米，C5水平为14.1毫米，C6水平为13.8毫米，C7水平为12.8毫米。终末骨未骨化组的BDI最大值为12毫米，终末骨已骨化组为10毫米。女性的BCDI正常上限为5.1毫米，男性为5.6毫米。
我们提出所获得的值作为1至15岁儿科人群CT图像上ADI、BDI、BCDI和PVSTT的正常上限值。
