Abstract:
Objective To assess scoliosis in adolescence and adults by three-dimensional ( 3-D ) ultrasound imaging . Methods A commercial available ultrasound instrument with a magnetic sensor system was used for long distance 3-D ultrasound imaging .Specific phantoms were imaged to evaluate the precision of this imaging system . Twenty healthy adults and 20 patients with scoliosis were imaged by 3-D ultrasonography and radiography . The deformity angle of the patients with scoliosis was measured on the reconstructed coronal plane ( C plane) of 3-D ultrasound imaging . The relevance between the curvature measured by ultrasound and the Cobb angles originated by radiography were evaluated . Results There was no significant difference between the angles of the phantom measured by the 3-D ultrasound imaging system and that measured by an angle gauge ( P = 0 .479) . The transverse process ,vertebral arch and acoustic shadow of the central spinous process of spines in healthy adults can be displayed on the reconstructed C plane by 3-D ultrasound imaging . The morphology of scoliosis in all the twenty patients can be observed on the reconstructed C planes ( multi-layers) by 3-D ultrasound imaging ,which accorded well with that observed on radiograph . In 9 patients ,part of the spinal segment could not be totally displayed on one single coronal plane and no additional measurement was carried out . In 11 patients ,all the segments of the spine could be clearly displayed on a single coronal plane and the curvature of scoliosis was then measured . There were no significant differences between the angle measured on 3-D ultrasound imaging and the Cobb angle measured on radiograph( P =0 .974) and the two measurement methods have high correlation( r =0 .991 , P <0 .0001) . Conclusions The commercial available 3-D ultrasound imaging system applied in this study offers a viable method to assess scoliosis in adolescence and adults in a reliable and radiation-free manner .
