Infrared thermography in the detection of brown adipose tissue in humans.

Jang C, Jalapu S, Thuzar M, Law PW, Jeavons S, Barclay JL, Ho KK - Physiol Rep (2014)

Bottom Line: A Δtemp of 0.9°C conferred a positive predictive value of 85% for SCV BAT, superior to that of SCV temperature.In conclusion, the Δtemp is significantly and consistently greater in BAT-positive subjects.The Δtemp quantified by IRT after 2-h cooling shows promise as a noninvasive convenient technique for studying SCV BAT function.

Representative PET‐CT and thermography images before and after 120‐min cooling for (A) two BAT‐positive subjects and (B) one BAT‐negative subject. In A, the thermograms for both PET‐positive subjects indicate that the skin temperatures in the SCVs are higher than the surrounding areas and with cooling, there is a fall in chest temperature as denoted by the color change. (B) Shows minimal difference in temperature between SCV and control chest areas. With cooling, there is no fall in chest temperature.

(B) Shows minimal difference in temperature between SCV and control chest areas. With cooling, there is no fall in chest temperature.

Mentions: Representative PET/CT scans and corresponding thermograms before and after cooling from two PET‐positive and a PET‐negative subject are shown in Figure 3. For the two positive scans, SCV temperatures are higher than the adjacent lateral areas before and after cooling. Note the fall in chest temperature after cooling. In the PET‐negative subject, the temperature in the SCV fossa is similar to the adjacent lateral area. There is no change in chest temperature after cooling.
