Table 2.
Mean ± StdDev of the trabecular bone structure measured variables for each CT protocol. Results are pooled for N = 3 repeated scans and 5 samples. BMD results are for post-hoc correction for PMMA-influence. Short-term reproducibility, CVSD(%), of the measured variables for each CT protocol. For XtremeCT only one scan per sample was available.
