title: Upright Biplanar Slot Scanning in Pediatric Orthopedics: Applications, Advantages, and Artifacts.
abstract: OBJECTIVE
  Digital slot scanning is a relatively new technology that has been used for imaging of pediatric orthopedic conditions such as scoliosis and leg-length discrepancies. This article will review the clinical applications, advantages, and unique artifacts of this new technology.
  
  
  CONCLUSIONS
  Upright biplanar slot scanners acquire high-resolution radiographs simultaneously in two orthogonal planes with reduced radiation dose. Other advantages include a more physiologic weightbearing imaging position, improved Cobb angle measurements, and 3D modeling.
