      Abstract

      Similar methods for measuring bone density using quantitative computed tomography have been proposed by Cann and Genant and by Firooznia et al. This study was done to evaluate the long-term reproducibility of quantitative computed tomography in the clinical setting. An anthropomorphic phantom was evaluated over an 18-month interval. A variation of ±2.2% was obtained, substantiating that quantitative computed tomography can be done in a reproducible manner over an extended time interval.
