Summary
Hyperspectral imaging (HSI) shows promise for real-time wound assessment, generating tissue oxygenation maps to predict healing risks. Further research is needed to integrate this advanced imaging technique into clinical practice for better wound care.
Area of Science:
- Medical imaging
- Wound care
- Biomedical engineering
Background:
- Multispectral and hyperspectral imaging (HSI) are advanced techniques with potential in patient wound care.
- Current HSI system capabilities for real-time tissue characterization and treatment guidance in wounds remain unclear.
Purpose of the Study:
- To systematically review hyperspectral imaging (HSI) systems assessed in patients over the last 32 years.
- To evaluate the potential of HSI for real-time tissue characterization and treatment guidance in wound management.
Main Methods:
- Systematic review of 140 studies published over 32 years.
- Analysis of 10 different in vivo hyperspectral imaging (HSI) systems used in patient assessments.
Main Results:
- Current in vivo HSI systems can generate tissue oxygenation maps.
- Tissue oxygenation measurements may predict wound formation or delayed healing risks.
- No safety concerns were reported; label-free HSI shows potential but requires further clinical integration.
Conclusions:
- Hyperspectral imaging (HSI) offers significant potential for non-invasive diagnosis and guidance in treating acute and chronic wounds.
- Further work is essential to integrate HSI into clinical workflows for diverse wound etiologies.
- HSI's ability to provide tissue oxygenation maps aids in predicting and managing wound healing.
