Radiation-therapy-induced erythema: comparison of spectroscopic diffuse reflectance measurements and visual assessment

Surveillance and assessment of radiation-induced erythema is an important aspect of managing skin toxicity in radiation therapy treated patients. Upon receiving the early fractions of radiation, an inflammatory response and vascular dilation takes place due to damage of basal cells in the skin’s epidermal layer. This process of skin reddening known as erythema. The gold standard used for assessing and grading erythema is visual assessment (VA) …
