Values for T1, T2, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) in the myocardium at t0 (mean ± standard deviation)
| Preparation | T1 (ms) | T2 (ms) | FA | ADC (×10−4, mm2/s) |
|---|---|---|---|---|
| (i) Standard agarose | 879 ± 63iii | 41.8 ± 8.2 | 0.28 ± 0.03 | 8.81 ± 0.13 |
| (ii) Fomblin | 787 ± 62iii | 27.5 ± 1.5iii | 0.27 ± 0.02 | 7.99 ± 0.60 |
| (iii) Iso-osmotic agarose | 1247 ± 124i,ii | 53 ± 16ii | 0.25 ± 0.03 | 8.74 ± 0.77 |
All values are means ± standard deviation. Mean value of T1 in (iii) is statistically significantly different from that in (i) (p < 0.01) and (ii) (p < 0.001). There is no statistically significant difference between T1 in (i) and (ii) (p > 0.05). The only significant difference in T2 values is between groups (ii) and (iii) (p < 0.05). There are no statistically significant differences between the mean FA and ADC values from each group. All comparisons determined by one-way analysis of variance followed by post-hoc Bonferroni multiple comparisons with other preparations. Superscripts show which preparations are significantly different within each category.
