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.

Mean (±SE) temperatures over the left (L) and right (R) supraclavicular areas (upper panel) and the anterior chest (lower panel) over 2 h of cooling at 19°C in an air‐conditioned room in subjects with positive and negative PET scans. *P <0.05 for fall in temperature with time; #P <0.05 for difference between PET‐positive and ‐negative groups.

fig01: Mean (±SE) temperatures over the left (L) and right (R) supraclavicular areas (upper panel) and the anterior chest (lower panel) over 2 h of cooling at 19°C in an air‐conditioned room in subjects with positive and negative PET scans. *P <0.05 for fall in temperature with time; #P <0.05 for difference between PET‐positive and ‐negative groups.

Mentions: Using FLIR Research IR Professional Analyzing Software (Version 1.2, Wilsonville, OR), skin temperatures overlying the SCV fossa bilaterally and an area in the upper chest just lateral to the sternum approximating the second intercostal space (control) were determined for each image. Analyses were performed for both right and left SCV regions (Fig. 1).
