What is Digital Infrared Thermography?
|
|
Thermography is a medical science that uses infrared images of the body to diagnose problems; often referred to as ‘digital infrared thermal imaging’, or DITI.
Medical DITI is a noninvasive diagnostic technique that allows the examiner to visualize and quantify changes in skin surface temperature. An infrared scanning device is used to convert infrared radiation emitted from the skin surface into electrical impulses that are visualized in color on a monitor.
This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colors indicate an increase or decrease in the amount of infrared radiation being emitted from the body surface. Since there is a high degree of thermal symmetry in the normal body, subtle abnormal temperature asymetry’s can be easily identified.
Medical DITI’s major clinical value is in its high sensitivity to pathology in the vascular, muscular, neural and skeletal systems, and can contribute to the clinician’s pathogenesis and diagnosis.

What are the clinical uses?
1. To define the extent of a lesion of which a diagnosis has previously been made
2. To localize an abnormal area not previously identified, so further diagnostic tests can be performed
3. To detect early lesions before they are clinically evident
4. To monitor the healing process before the patient is returned to work or training
Skin blood flow is under the control of the sympathetic nervous system. People under healthy homeostasis have symmetrical dermal patterns which is consistent and reproducible. This is recorded in precise detail with a temperature sensitivity of 0.1℃ by DITI.

How do I prepare?
- No smoking 2 hours before exam
- No vigorous exercise 2 hours prior to exam
- No strong sun exposure prior to exam
- No sunburns
- No bodywork i.e Chiropractic, Massage, Acupuncture etc 24 hours prior to scan
- No oils, lotions, perfumes, gels etc
- No change in diet or medication
- Remove all Jewelry
- Loose fitting clothing and underwear that can be tucked or rolled out of imaging views
How the technology works.
The neuro-thermography application of DITI measures the somatic component of the sympathetic nervous system by assessing dermal blood flow. The sympathetic nervous system is stimulated at the same anatomical location as its sensory counterpart and produces a ‘somato sympathetic response’. The somato sympathetic response appears on DITI as a localized area of altered temperature with specific features for each anatomical lesion.
The mean temperature differential in peripheral nerve injury is 1.5℃. In sympathetic dysfunction’s (RSD / SMP / CRPS) temperature differentials ranging from 1℃ to 10℃ depending on severity are not uncommon.
Rheumatological processes generally appear as ‘hot’ areas with increased temperature patterns. The pathology is generally an inflammatory process, i.e. synovitis of joints and tendon sheaths, epicondylitis, capsular and muscle injuries, etc.
Both hot and cold responses may coexist if the pain associated with an inflammatory focus excites an increase in sympathetic activity. Also, vascular conditions are readily demonstrated by DITI including Raynauds disease, Vasculitis, Limb Ischemia, DVT, etc.
Medical DITI is filling the gap in clinical diagnosis …
X ray, C.T. Ultrasound and M.R.I. etc., are tests of anatomy. E.M.G. is a test of motor physiology. DITI is unique in its capability to show physiological change and metabolic processes. It has also proven to be a very useful complementary procedure to other diagnostic modalities. Unlike most diagnostic modalities DITI is non invasive. It is a very sensitive and reliable means of graphically mapping and displaying skin surface temperature. With DITI you can aid diagnosis, evaluate, monitor and document a large number of injuries and conditions, including soft tissue injuries and sensory/autonomic nerve fiber dysfunction.
Medical DITI can offer considerable financial savings by avoiding the need for more expensive investigation for many patients.
Medical DITI can graphically display the very subjective feeling of pain by objectively displaying the changes in skin surface temperature that accompany pain states.
Medical DITI can show a combined effect of the autonomic nervous system and the vascular system, down to capillary dysfunctions. The effects of these changes show as asymmetry’s in temperature distribution on the surface of the body.
Medical DITI is a monitor of thermal abnormalities present in a number of diseases and physical injuries. It is used as an aid for diagnosis and prognosis, as well as therapy follow up and rehabilitation monitoring, within clinical fields that include Rheumatology, neurology, physiotherapy, sports medicine, oncology, pediatrics, orthopedics, Massage therapy and many others.
Results obtained with medical DITI systems are totally objective and show excellent correlation with other diagnostic tests.
Medical DITI has been used extensively in human medicine in the U.S.A., Europe and Asia for the past 20 years. Until now, cumbersome equipment has hampered its diagnostic and economic viability. Current state of the art PC based infrared technology designed specifically for clinical application has changed all this.
