Total Body Imaging

What is a TBI?

A total body image (TBI) is created by taking a series of photographs of the skin surface of a patient which can then be examined individually or as a composite. It is a technique used by dermatologists that provides them with a record of existing skin lesions and gives them something to compare the appearance of new lesions against, rather than just having to rely on either their own, or the memory of the patient, as to when a mark first appeared on the skin and its subsequent changes in size, color, etc.

The ability to identify new marks or lesions in a timely fashion has a major impact on the efficiency of the management of skin cancer. Through early detection, removal of any cancerous lesions becomes much less destructive both physically and emotionally. Advances in technology (e.g. the use of digital cameras to produce images on a computer screen) have greatly enhanced our ability to recognize both pre-existing and newly emergent skin lesions by providing better image manipulation (including magnification to greater than the human eye) and allowing side-by-side comparisons of pictures taken over a period of time.

Who should have a TBI done?

1. Anyone with a prior history of any kind of skin cancer, or with a family history of skin cancer can benefit from this kind of exam as a means to identify possible cancerous lesions at an early stage.

2. Anyone in a high risk group (e.g. fair skinned individuals who have had 2 bad sunburns before the age of 20, individuals with a high number of existing moles) may wish to consider having a TBI done as a preventative measure.

3. If you are unsure whether a TBI would be appropriate for you, then consult your dermatologist.

 

What is the procedure?

If in consultation with your dermatologist you decide that you are a candidate for a TBI, then an appointment will be scheduled at a convenient time for you. The process of taking the serial pictures of the body takes approximately one hour, so make sure you leave yourself plenty of time. You will be asked to remove your outer clothes (you may leave your underwear on if you wish), and put on a gown. A series of pictures covering the head and neck areas will then be taken - the photographer may ask for your assistance here to hold your hair out of the way. You will then be asked to remove the gown and a full series of pictures of the body and limbs is done. To facilitate the process we ask that ladies do not wear any makeup, and that watches and jewelry are removed.

After the images are taken, the dermatologist will examine you in the areas that are hard to image such as the oral cavity and scalp. After the appointment, your dermatologist will review the images, and if anything is considered to need further attention you will be notified. Your dermatologist will recommend an appropriate time frame after which another series of images will be taken.
