Ultrasound-Guided Optical Coherence Tomography Needle Probe for the Assessment of Breast Cancer Tumor Margins

OBJECTIVE. The purpose of this study was to evaluate a new imaging technique for the assessment of breast cancer tumor margins. The technique entails deployment of a higresolution optical imaging needle under ultrasound guidance. Assessment was performed on fresh ex vivo tissue samples. CONCLUSION. Use of the ultrasound- guided optical needle probe allowed in situ assessment of fresh tissue margins. The imaging findings corresponded to the histologic findings.
