79 OBJECTIVE EVALUATION OF ANGIOGENESIS USING MICRO CT AND PHOTOGRAPHY 4 Figure 4. Vascular volume of control and nerve autograft samples at 12 and 16 weeks using micro CT. Results are expressed as a percentage (vessel %) of the total nerve area and are given as the mean ±SEM. *Indicates significance at P<0.05. SEM: Standard error of the mean. Vascular surface area measured with conventional photography After 12 weeks, the vascular surface area was 26.87% ± 2.13 (mean ± SEM) for the non-operated control nerve samples, compared to 25.04% vessel ± 2.77 for the nerve autograft sample. After 16 weeks the control samples measured a vascular surface area of 33.71% ± 2.60 and 28.11% ± 3.47 for the autograft nerves. No significant differences were found between the groups or time points (Figure 5). Correlations The vascular volume and vascular surface area were significantly correlated with both time points and groups (r=0.951, P=0.049).
