Abstract
Background: Diagnosis of actinic keratosis (AK) based only on clinical findings can be misleading, and histopathological diagnosis results in scars. Dynamic thermal imaging is a potential non-invasive tool for the diagnosis of AK. This imaging technique quantifies the infrared (IR) radiation emitted by a subject after exposure to external thermal stimuli, such as heat or cold. Methods: Twenty-six histopathologically confirmed AK patients participated in the study. We compared the dynamic thermal images of AK lesions and normal skin (control sites). Temperature changes were plotted as a thermal response graph. After fitting exponential curves to the thermal response graph, the curve was converted to a logarithmic form. Results: Comparison of the early thermal response graphs of lesions and control sites showed faster thermal recovery of AK lesions. There was a significant difference in the gradient component of the calculated logarithmic equation between the AK lesions and control sites (P < 0.001). Conclusion: Dynamic thermal imaging can be used as an auxiliary diagnostic tool for AK.
