Reliability and Reproducibility of Subject Positioning with EOS Low-Dose Biplanar X-ray.

ABSTRACT:

Background

EOS low-dose biplanar X-ray used with tantalum bead implantation is an appealing imaging modality to evaluate limb length and physeal growth due its relatively low radiation exposure, excellent inter- and intra-observer reliability, and minimal magnification/shrinkage error.

Questions/purposes

The purpose of this study was to establish the error in total length and inter-bead distances using EOS and tantalum beads due to variable positioning in the EOS gantry, by assessing variation in measurements made on the same subject repeatedly positioning by one positioner (intra-positioner measurement error) and variation in measurements made on the same subject with positioning by multiple positioners (inter-positioner measurement error).

Methods

Tantalum bead mark
