Infrared Thermography Associated With Cutaneous Microcirculation for Detection of Brown-adipose Tissue (MICROBAT) (MICROBAT)
November 12, 2022 updated by: University of Avignon
Infrared Thermography Associated With Cutaneous Microcirculation for Detection of Brown-adipose Tissue: Proof of Concept Against PET-CT in Patients Affected by Pheochomocytoma and/or Paraganglioma
Patients affected by pheochromocytoma (PHEO) have brown-adipose tissue (BAT) hyperactivation.
They perform, in routine settings, a FDG PET-CT scan.
The high metabolic activity of BAT and its ability to consume both glucose and fatty acid suggest that it may have potential as a therapeutic target in the treatment of obesity.
However, alternative non-invasive techniques to PET-CT BAT detection still need more validation.
Accordingly, our aim will be to measure the temperature and microcirculation of the skin overlaying BAT depots in the region of FDG-uptake detected by 18F-FDG PET/CT before and after a cold test in PHEO patients.

Detailed Description
Objectives and Methodology:
- To analyse the change in temperature and microcirculation of the skin overlaying BAT depots in the region of FDG-uptake detected by 18F-FDG PET/CT before and after a cold test in PHEO patients.
- To check the decreased temperature and microcirculatory response after a cold test following resection of the tumor
All the patients affected by will benefit from a:
- clinical: treatments
- biological evaluations: glycemia, triglycerides, total cholesterol, HDL-C, LDL-C, plasma epinephrine and norepinephrine, urine catecholamine
- cutaneous microcirculation by means of Laser Speckle Imaging will be recorded at rest and during a cold test in the supra-clavicular region
- cutaneous microcirculation by means of Laser Doppler Flowmetry will be recorded at rest and during a cold test with one probe in the supra-clavicular region and one probe in umbilical region
- skin temperature by means of infrared thermography will be recorded at rest and during a cold test in the supra-clavicular region
Patients who will have surgery will be investigated before and after one year following resection of the tumor.
