Description
Summary:Abstract Study Design Retrospective review of magnetic resonance imaging (MRI) and computed tomographic (CT) scan imaging modalities. Objective To determine MRI's capability of identifying pedicle morphology. Summary of Background Data Understanding pedicle morphology is important for accurate placement of pedicle screws. The gold standard modality to assess pedicle morphology is CT scan. However, CT scans carry the risk of radiation exposure. We have studied MRI as a potential alternative to CT scan. Methods Nine hundred seventy pedicles in 33 spinal deformity patients were reviewed. Pedicle morphology was classified as follows: Type A (normal pedicle): >4-mm cancellous channel; Type B: 2–4-mm channel; Type C: any size cortical channel; and Type D:
