The Value of MRI 3D-DESS Technique in Preoperative Evaluation of Polydactyly in Children
Objective To explore the value of magnetic resonance(MR)3 Dimensions-Double echo steady state(3D-DESS)technique in preoperative evaluation of polydactyly in children.Methods 18 children were prospectively enrolled in this study,who were clinically diagnosed as polydactyly in the Department of Orthopaedics of our hospital from May 2021 to April 2022.Preoperative MRI 3D-DESS scan was performed.Image quality was analyzed by two senior radiologists using a double-blinded 3-point scale,and the intraoperative results were used as the"gold standard"to analyze the consistency of image results and intraoperative results.Results All the 18 children performed MRI scanning successfully.The epiphysis,tendon and bone tissue were clearly showed.All the image quality met the diagnostic requirements,of which the score of 16 cases(88.9％)was 3 point,with an average score of 2.6±0.3.ICC value of two doctors'assessments of image quality was 0.8579(95％Cl:0.7253-0.9658).The image results of all the cases were consistent with intraoperative findings.Conclusion Non-invasive and radiation-free MR 3D-DESS technique can provide the growth and development information of cartilage epiphysis,tendon and bone tissue of polydactyly in children before surgery,which has high value for preoperative evaluation and preparation of surgical treatment.
