Table 1
Characteristics of molecular imaging modalities and representative examples for nanoparticle-based cancer imaging probes.
| Modality
| Spatial resolution
| Penetration depth | Sensitivity (mol/L) | Cost | Nanomaterial |
| | PET | 1-2 mm | No limit | High (10−11–10−12) | | Polymer
| | CT | 50–200 μm | No limit | Low (10−1–10−4) | | Gold nanoparticle, USPIO nanoparticle
| | MRI | 25–100 μm | No limit | Low (10−3–10−5) | | Paramagnetic liposome, USPIO nanoparticle
| | US | 50–500 μm | mm-cm | Medium | | Microbubble
