    Dynamic thermography quantifies regional dermal perfusion by measuring skin reheating after a cold challenge. Subcutaneous fat thickness significantly impacts results, limiting precise blood flow quantification but enabling regional perfusion insights.

    Area of Science:

    • Physiology
    • Biomedical Engineering

    Background:

    • Dermal perfusion assessment is crucial for understanding skin physiology and various medical conditions.
    • Existing methods for quantifying skin blood flow have limitations in regional specificity and accuracy.

    Purpose of the Study:

    • To investigate a novel dynamic thermographic technique for regional dermal perfusion quantification.
    • To evaluate the relationship between skin reheating rates and dermal perfusion following a cold challenge.

    Main Methods:

    • Utilized a dynamic thermographic technique with a Philips thermographic camera.
    • Applied a transient cold challenge to volar forearm skin and measured surface reheating rates.
    • Correlated reheat temperatures with subcutaneous fat thickness and dermal blood flow changes.

    Main Results:

    • The technique demonstrated good repeatability for measurements on normal subjects.
    • Normalized reheat temperatures were highly dependent on subcutaneous fat thickness.
    • The method showed low sensitivity to minor changes in dermal perfusion but detected hyperaemia induced by prostaglandin E2.
    • Intersubject variations in fat thickness limited precise quantification of blood flow.

    Conclusions:

    • Dynamic thermography offers valuable insights into regional skin perfusion variations.
    • Quantifying absolute skin blood flow using reheat rates is limited by sensitivity and fat thickness dependency.
    • The technique shows potential for assessing regional perfusion where static measurements are insufficient.
