Digital Infrared Thermal Imaging In Medical Therapy by: Brenda Witt Digital technology now makes Digital Infrared Thermal Imaging available to all. There now is a completely safe test that can aid in diagnosis, treatment and monitoring with absolutely no risk or radiation exposure. DITI, or digital infrared thermal imaging, is a noninvasive diagnostic test that allows a health practitioner to see and measure changes in skin surface temperature. An infrared scanning camera translates infrared radiation emitted from the skin surface and records them on a color monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colors indicates an increase or decrease in the amount of infrared radiation being emitted from the body surface. In healthy people, there is a symmetrical skin pattern which is consistent and reproducible for any individual. DITI is highly sensitive and can therefore be used clinically to detect disease in the vascular, muscular, neural and skeletal systems. Medical DITI has been used extensively in human medicine in the United States, Europe and Asia for the past 20 years. Until now, bulky equipment has hindered its diagnostic and economic feasibility. Now, PC-based infrared technology designed specifically for clinical application has changed all this. Clinical uses for DITI include, defining the extent of a lesion of which a diagnosis has previously been made (for example, vascular disease); localizing an abnormal area not previously identified, so further diagnostic tests can be performed (as in Irritable Bowel Syndrome); detecting early lesions before they are clinically evident (as in breast cancer or other breast diseases); and monitoring the healing process before a patient returns to work or training (as in workman's compensation claims). Medical DITI is filling the gap in clinical diagnosis; X-ray, Computed Tomography, Ultrasound and Magnetic Resonance Imaging (MRI), are tests of anatomy or structure. DITI is unique in its capability to show physiological or functional changes and metabolic processes. It has also proven to be a very useful complementary procedure to other diagnostic procedures. 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 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 biased feeling of pain by accurately displaying the changes in skin surface temperature. Disease states commonly associated with pain include Reflex Sympathetic Dystrophy or RSD, Fibromyalgia and Rheumatoid arthritis. 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 reveal an asymmetry in temperature distribution on the surface of the body. 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 and many others. Results obtained with medical DITI systems are totally objective and show excellent correlation with other diagnostic tests. Thermographic screening is not covered by most insurance companies but is surprisingly affordable for most people.
