Improving Therapy for Children with Scoliosis through Reducing Ionizing Radiation by Using Alternative Imaging...

Area of Science:

• Orthopedics
• Radiology
• Pediatric Medicine
• Medical Imaging

Background:

• Scoliosis diagnosis and treatment often involve multiple, high-radiation imaging modalities.
• There is a need to reduce radiation exposure in pediatric scoliosis management.
• Current protocols require interdisciplinary collaboration for effective patient care.

Purpose of the Study:

• To evaluate the feasibility of replacing computed tomography (CT) scans with magnetic resonance imaging (MRI) for scoliosis diagnosis and surgical planning.
• To assess the potential of radiation-free or low-radiation methods for follow-up examinations.
• To establish an interdisciplinary standard protocol for scoliosis management, reducing radiation exposure and perioperative risks.

Main Methods:

• Analysis of 50 pediatric scoliosis patients (aged 7-18 years).
• Retrospective reformatting of thin-slice 3D MRI sequences from preoperative MRI scans.
• Acquisition of 3D back scans (video-raster stereography) and intraoral scans.
• Comparison of MRI and 3D back scan data with conventional radiographs, CT, and EOS imaging.

Main Results:

• Investigating whether thin-slice 3D MRI reconstruction can replace CT for preoperative planning.
• Determining if EOS or whole-spine X-rays combined with MRI suffice for evaluating pedicles and spinal deformity.
• Correlating Cobb angle measurements from radiographs with back scanner data for potential follow-up replacement.
• Exploring correlations between dental anomalies and scoliosis.

Conclusions:

• Thin-slice MRI reconstruction may replace CT-based imaging for scoliosis assessment.
• Three-dimensional back scans show promise as an alternative to X-rays for monitoring severe scoliosis.
• Identifying correlations between scoliosis and dental anomalies could lead to earlier orthodontic interventions, benefiting long-term therapy.
