Tumor-to-Nontumor Ratios in Nude Mice with HT-29 Tumor Xenografts After Intravenous Injection of 3.5–4 MBq 99mTc(CO)3NT-VIII
| Time after injection (h) | Tu/Bl | Tu/Ki | Tu/Li | Tu/In |
|---|---|---|---|---|
| 1.5 | 14.8 ± 8.7 | 0.5 ± 0.2 | 1.5 ± 0.5 | 3.3 ± 0.4 |
| 3 | 33.3 ± 4.0 | 0.7 ± 0.1 | 1.9 ± 0.1 | 3.7 ± 0.7 |
| 5 | 15.6 ± 2.0 | 0.5 ± 0.1 | 1.8 ± 0.4 | 4.5 ± 0.9 |
| 15 | 45.4 ± 8.0 | 0.8 ± 0.2 | 2.2 ± 0.5 | 5.5 ± 0.6 |
| 24 | 31.8 ± 14.0 | 0.8 ± 0.3 | 2.1 ± 1.0 | 3.9 ± 0.9 |
Tu = tumor; Bl = blood; Ki = kidney; Li = liver; In = intestine.
Data are mean ± SD of individual ratios (n = 3–6 animals).
