Summary
Spectroreflectometry can determine the age of human haematomas. Wavelengths of 560 and 580 nm show significant differences in monocle-haematomas older than two days.
Area of Science:
- Medical Imaging
- Forensic Science
- Biophysics
Context:
- Assessing the age of haematomas is crucial in clinical and forensic settings.
- Current methods for determining haematoma age can be imprecise.
- Spectroreflectometry offers a non-invasive approach to analyse tissue changes.
Purpose:
- To evaluate the efficacy of spectroreflectometry for determining the age of human haematomas.
- To identify optimal wavelengths for accurate haematoma age determination.
- To establish the method's reliability for superficial skin haematomas and monocle-haematomas.
Summary:
- Spectroreflectometric measurements (430-700 nm) were performed on 52 artificial and 40 monocle-haematomas.
- Optimal results were achieved using wavelengths of 560 nm and 580 nm.
- Significant age differentiation was observed for monocle-haematomas exceeding two days.
Impact:
- Provides a novel, objective method for estimating haematoma age.
- Potential applications in forensic medicine and clinical diagnostics.
- Enhances the accuracy of post-injury time assessment.
