Summary
Combining diffuse optical tomography and fluorescence imaging with scatterplots enhances breast lesion detection. This method successfully identified subtle lesions missed by individual imaging techniques, aiding in tumor differentiation.
Area of Science:
- Biomedical Optics
- Medical Imaging
- Cancer Detection
Background:
- Diffuse optical tomography (DOT) and fluorescence imaging are valuable tools for breast lesion detection.
- Limitations exist in detecting small or low-contrast lesions with these methods alone.
Purpose of the Study:
- To investigate the combined use of DOT and fluorescence imaging with scatterplots for improved breast lesion detectability.
- To assess the capability of scatterplots in differentiating malignant lesions from normal tissues.
Main Methods:
- Utilized scatterplots generated from 2 or 3 parameters derived from diffuse optical tomography and fluorescence imaging data.
- Evaluated the method's performance on phantoms with simulated lesions and in patient measurements.
Main Results:
- Scatterplots successfully detected small or low-contrast phantom-lesions missed by individual imaging techniques.
- All tumors in patient measurements were clearly visible and distinguishable from artifacts and areolas in scatterplots.
- Differential uptake and washout rates of fluorescent contrast agents in healthy versus malignant tissues were observable in scatterplots.
Conclusions:
- Combining DOT and fluorescence imaging with scatterplots significantly improves breast lesion detection.
- Scatterplot analysis provides crucial information for differentiating malignant lesions from normal structures based on contrast agent kinetics.
