Kurzfassung:
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 .
