Main Scintigraphic Parameters Compared Between Tetrofosmin and 99mTc-DTPA by Paired Student t Test
| Scintigraphic parameter | Tetrofosmin | 99mTc-DTPA | P |
|---|---|---|---|
| Total uptake index (%) | 13.17 ± 4.76 | 8.33 ± 2.45 | <0.0001 |
| Right-kidney uptake index (%) | 6.77 ± 2.60 | 4.40 ± 1.46 | <0.0001 |
| Left-kidney uptake index (%) | 6.39 ± 2.64 | 3.92 ± 1.41 | <0.0001 |
| Right-kidney SKU (%) | 51.56 ± 9.29 | 53.04 ± 10.55 | NS |
| Left-kidney SKU (%) | 48.44 ± 9.29 | 46.96 ± 10.55 | NS |
| Right-kidney TP (min) | 3.18 ± 0.74 | 2.70 ± 0.74 | NS |
| Left-kidney TP (min) | 2.92 ± 0.65 | 2.95 ± 0.83 | NS |
SKU = separate kidney uptake (percentage of total-kidney uptake); NS = not statistically significant; TP = time to peak activity.
Data are mean ± SD. Uptake index is in percentage injected dose.
