报告摘要：Scoliosis is a spinal deformity characterized with three dimensional lateral curvature and axial vertebral rotation. Eighty percent of scoliosis cases are idiopathic, and it is usually detected on the juvenile and adolescent stages (JIS or AIS) with the prevalence ranged from 2% to 4%. Ultrasound techniques have been applied to the diagnosis and treatment of scoliosis, especially for the monitoring and prediction of the spine curve change. The spine imaging method reconstructed a full-spine 3D image based on the transverse reflection intensity images in accordance with the obtained location and orientation information. The results of the spine curve measurement from the ultrasound images are comparable to the conventional radiography, and the difference and correlation between the two modalities are less than 3 degree and higher than 90%. Moreover the ultrasound techniques can be used to estimate the curve flexibility and curve change during brace casting, which shows considerable advantages over the conventional radiography. The US techniques are radiation-free, easy to operate, mobile and cost-effective and become a great promising clinical tool for the diagnosis and treatment of Scoliosis.
