Table 1. Comparative ultrasonography indicator analysis of the Targeted NBs and Blank NBs in 3 types of xenografts.
| Contrast Agents | Arrival Time (s) | Time to Peak (s) | Peak Intensity (dB) | Imaging Duration (min) | |
|---|---|---|---|---|---|
| LNCaP tumor | Blank NBs | 2.40±0.03 | 9.41±0.11 | 19.62±0.44 | 20.20±0.28 |

| MKN45 tumor | Blank NBs | 2.20±0.02 | 9.40±0.12 | 18.46±0.29 | 22.14±0.56 |
| Targeted NBs | 2.21±0.03 | 9.38±0.10 | 18.50±0.33 | 22.23±0.53 | |
The data are presented as the means ± SD (n = 5).
*P <0.05 indicates the level of significance compared with Blank NBs in the same types of xenografts;
#P <0.05 indicates the level of significance compared with targeted NBs in the gastric cancer xenografts (MKN45);
+P <0.05 indicates the level of significance compared with targeted NBs in the C4-2 xenografts.
