Optical spectroscopy techniques can accurately distinguish benign and malignant renal tumours

What's known on the subject? and What does the study add? There is little known about optical spectroscopy techniques ability to evaluate renal tumours. This study shows for the first time the ability of R aman and optical reflectance spectroscopy to distinguish benign and malignant renal tumours in an ex vivo environment. We plan to develop this optical assistance in the operating room in the near future. Objective To evaluate the ability of R...
