Abstract

Introduction The aim of this study was to compare the compliance of sacrum ultrasonography with radiography for the measuring of sacral ratio in infants. Materials and Methods A total of 129 infants under the age of 6 months, who were a candidate for abdominal and/or pelvic radiographs, were assessed. Sacrum ultrasonography and radiography were performed by a single radiologist using the same device. The sacral ratio was calculated for all patients undergoing ultrasonography and radiography. Agreement between two methods was calculated by Bland-Altman's chart. Results The mean of sacral ratio was 0.70 ± 0.11 radiographically and 0.72 ± 0.05 ultrasonographically. Based on Bland-Altman's chart, the mean difference between ultrasonography and radiology was 4.6 mm (confidence intervals of 8.18 ± 5.6). Conclusion Sacrum ultrasonography could be safely used in the investigation of sacral ratio to detect sacrum abnormalities in infants. © 2021 Georg Thieme Verlag. All rights reserved.
