A comparison of five different imaging modalities for chronic wound diagnosis
| Imaging modalities | Application in chronic wound imaging | Spatial resolution | Safety | Real time | Time consuming | Cost | Penetration depth |
|---|---|---|---|---|---|---|---|
| CT | Assessment of bone and joint pathology around wounded region. | High | Ionizing radiation | No | Medium | Medium | High |
| SPECT/CT | Assessment of regional microvascular perfusion in lower extremities. | High | Ionizing radiation | No | High | High | High |
| MRI | Soft tissue and bone pathology evaluation. | Low | General safe | Sometimes | High | High | High |
| Ultrasound imaging | Dermatology, assessment of wound structure and speed of flowing blood. | High | Safe | Yes | Low | Low | Low |
| THz spectroscopy | Assessment of burn wound | Medium | Safe | Sometimes | Low | Low | Medium |
CT, computed tomography; MRI, magnetic resonance imaging; SPECT, single-photon emission computed tomography; THz, terahertz.
