Nowadays, Thermography is one the most modern means of diagnosis by digital image. It can detect several diseases, innumerous times not detected by other methods, and earlier in time.
It is a noninvasive exam and with no physical contact. Also doesn’t emit any kind of radiation and is completely painless. So it can be used in children and pregnant women, in which can be made exams without any type of risk. It’s also particularly indicated for people who have been submitted to other types of exams and painful procedures that show resistance in having more exams or diagnosis tests.
Thermography can be repeated as many times as necessary without any risk or pain for the patient.
Right Breast Cancer
- Hyperthermia on the superior corner of the right breast with signs of metastasis on the clavicle area.
- Hypothermia on the sternum indicating a immunodeficiency caused by thymus mal function.
Physiological and physiopathological bases of Thermography:
The body heat dissipation (thermic energy) happens, in great part, by infrared radiation dependent of the subcutaneous circulatory flow and blood volume. This heat comes, mainly from muscular metabolic activity and depending of the digestive phase in which the person is at the moment, it can be, in a smaller part, from visceral metabolic activity.
More than 90% of the blood supply of the skin passes through less than 0,3mm diameter arterioles, directly connected to the venous plexus (shunts), to regulate the body temperature and only 10% is for the capillary system which nourishes the skin. These subcutaneous venous bridges are connected to the muscle tissue and will have longer or shorter length, depending on the thickness of the adipose tissue and make a flow against the stream with the arteriolar system, which serves to give more thermic balance to the blood, due to the existing trade between venules and arterioles.
Usually around 3 to 4% of the cardiac output is for the subcutaneous flow and in heat stress conditions the flow can increase 10 times and the blood flow of the cutaneous nourishing capillary system can have only 1% of the cardiac output. The blood flow of the subcutaneous arteriolar and venule net is controlled by the sympathetic nervous system (noradrenaline), decreasing it and therefor decreasing the infrared emissivity. So, any pathology that affects directly or indirectly the sympathetic nervous system will produce a decrease of the infrared emissivity (hypothermia) and in case of failure of this decrease, it will occur an increase of the blood flow and therefor an increase of the emissivity.
In case of painful pathologies of inflammatory neurogenic origin, infectious or not, it will occur, on the type C nervous terminations level, the release of the substance P, or capillary endothelial or macrophages, the production and/or the release of nitric oxide producing an intense vasodilatation and therefor a significant increase of the emissivity of the infrared (hyperthermia).
In inflammatory pathologies by trauma, rheumatic or infectious, we have the production and release of prostacyclin and bradykinin, potent vasodilators which will release substance P and nitric oxide. We will also have hyperthermic changes, or hypothermic in specific pathologies that affect directly or indirectly the venous, arterial and/or micro vascular system.
Face hyperthermia indicates rhinitis.
THE PRECISION AND ACCURACY WITH THERMOGRAPHY:
The human body is composed by thousands of elements which can become unbalanced. It is hard, if not impossible, to analyze every single element, many times the stronger the symptoms the deepest the cause. For example a thoracic pain is many times a reflex of digestive or bile problems that affect the spine, and not an osteo-articular situation. With thermography we can understand that connection.
Thermography allows you to discover injuries and health problems you wouldn’t even imagine you had, because you don’t feel pain or have a sign that alerts you. This possibility is very important because we all know that, e.g. cancer, doesn’t appear suddenly and when it is detected usually is too late. With thermography we can highlight situations that till then were hidden, allowing us the possibility to develop a preventive action.
With thermography we can make the connection and establish the relation between different pathologies, and specially choose the areas, organs or meridians where to act in first place.
