What is Thermography?
Thermography or DITI (Digital Infrared Thermal Imaging) is an affordable and totally
non-invasive, painless screening with no radiation and no contact with the body.
What is Thermography used for?
To help in determining the cause of pain.
To aid in the early detection of disease and pathology
To evaluate sensory-nerve irritation or significant soft-tissue injury
To define a previously diagnosed injury or condition
To identify an abnormal area for further diagnostic testing
To follow progress of healing and rehabilitation.
Overview of Thermography
Medical DITI is a noninvasive diagnostic technique that allows the examiner to visualise 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 visualised in colour on a monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colours 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.
Preparation for Thermography
There are a few guidelines for preparing for a thermal scan:
Do not have physical therapy, massage, or electromyography on the same day thermography is performed.
Do not participate in vigorous exercise 2 hours prior to the test.
Do not smoke for 2 hours before the test.
Do not use lotions, deodorants, powder or antiperspirant or shave on day of test.
Stay out of strong sunlight on the day of test.
Do not have body work or acupuncture 3 days prior.
Wait 3 months post surgery, radiation therapy, and chemotherapy.
Wait 3 months post lactation.
There are no dietary or medication restrictions on the day of your scan but no
excessive hot or cold drinks prior to the test.
What to expect
A thermal scan takes approximately 10 to 45 minutes depending on which part of the body is being scanned. You will remove all jewelry and clothes from the part of the body being scanned (for full body scans you leave underpants on). For a breast scan, you will be ask to disrobe from the waist up. You will need to sit for a few minutes while your skin is equalizing with the room temperature. At that time we will go over your paper work.
Who interprets my images and writes the report?
Medical doctors or themologists who represent a variety of specialties such as Emergency Medicine, Functional Medicine, OB/GYN, General Practice, and Radiology interpret the thermal images for abnormal heat patterns and asymmetries. Board certification and training is provided by the American College of Clinical Thermology (ACCT). The report is usually ready within 3-5 business days.
