Title: | Validity study of vertebral rotation measurement using 3-D ultrasound in adolescent idiopathic scoliosis | Authors: | Wang, Q Li, M Lou, EHM Chu, WCW Lam, TP Cheng, JCY Wong, MS |
Issue Date: | Jul-2016 | Source: | Ultrasound in medicine and biology, July 2016, v. 42, no. 7, p. 1473-1481 | Abstract: | This study aimed to assess the validity of 3-D ultrasound measurements on the vertebral rotation of adolescent idiopathic scoliosis (AIS) under clinical settings. Thirty curves (mean Cobb angle: 21.7° ± 15.9°) from 16 patients with AIS were recruited. 3-D ultrasound and magnetic resonance imaging scans were performed at the supine position. Each of the two raters measured the apical vertebral rotation using the center of laminae (COL) method in the 3-D ultrasound images and the Aaro-Dahlborn method in the magnetic resonance images. The intra- and inter-reliability of the COL method was demonstrated by the intra-class correlation coefficient (ICC) (both [2, K] >0.9, p < 0.05). The COL method showed no significant difference (p < 0.05) compared with the Aaro-Dahlborn method. Furthermore, the agreement between these two methods was demonstrated by the Bland-Altman method, and high correlation was found (r > 0.9, p < 0.05). These results validated the proposed 3-D ultrasound method in the measurements of vertebral rotation in the patients with AIS. | Keywords: | 3-D ultrasound Adolescent idiopathic scoliosis Measurement Reliability Validity Vertebral rotation |
