Upright Biplanar Slot Scanning in Pediatric Orthopedics: Applications, Advantages, and Artifacts

Nathan C Hull et al. AJR Am J Roentgenol. 2015 Jul.

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.

Conclusion: 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.

Keywords: as low as reasonably achievable (ALARA); digital slot scanning; limb abnormalities; orthopedics; scoliosis.
