Equilibration between breast surface and ambient temperature by liquid crystal thermography

Area of Science:

• Medical Imaging
• Thermology
• Oncology

Background:

• Breast thermography is used for evaluating breast health.
• A cooling period before thermography is debated for accuracy.
• Skin temperature changes may affect lesion detection.

Purpose of the Study:

• To determine the significance of a waiting period before breast thermography.
• To investigate thermal equilibrium achievement in breast skin temperature.
• To assess the impact of cooling on thermographic evaluation.

Main Methods:

• Nine ovulatory women underwent thermography twice during their menstrual cycle.
• Breast thermograms were recorded every minute for 20 minutes post-exposure.
• A cholesteric liquid crystal contact plate was used at 72°F (22°C).

Main Results:

• Breast skin temperature showed a significant drop within the first 15 minutes.
• Thermal equilibrium was not achieved until after 15 minutes.
• This temperature drop suggests a need for a waiting period.

Conclusions:

• A waiting period is necessary for accurate breast thermography.
• Thermal equilibrium is achieved after approximately 15 minutes.
• Standardizing the cooling period enhances diagnostic reliability.
