Reproducibility of Functional Measurements in Infarcted Rats
| Parameter | Mean | Reproducibility |
| Interscan (n = 8) | ||
| Ejection fraction | 45% | 3.6% ± 2.4% |
| Diastolic volume | 834 mm3 | 49 ± 12 mm3 |
| Systolic volume | 462 mm3 | 37 ± 17 mm3 |
| Intersubject (n = 5) | ||
| Ejection fraction | 45% | 8.1% ± 2.4% |
| Diastolic volume | 832 mm3 | 126 ± 20 mm3 |
| Systolic volume | 462 mm3 | 121 ± 14 mm3 |
Volumes are after normalization. Because interscan data are normalized to average weight of each rat, and intersubject data are normalized to average weight of all rats for each scan, the means differ slightly.
