Fluorescence Visualization Technology

We would like to share with you a new diagnostic tool we have in our practice that has significantly improved both our diagnostic and treatment capabilities of suspicious oral lesions. The VELscope system is a hand-held device developed by the British Columbia Cancer Agency in association with the MD Anderson Cancer Center and funded, in part, by the NIH that uses fluorescence visualization technology to differentiate between normal and abnormal tissue. It is the only adjunctive device cleared by the FDA to help discover oral mucosal lesions that might not be apparent or visible to the naked eye.

The system emits a very specific blue wavelength of light into the oral cavity, which excites the tissue from the surface of the epithelium through to the basement membrane and into the underlying connective tissue stroma causing it to fluoresce. Under examination with the VELscope system’s patented lens, abnormal tissue typically appears as an irregular, dark area that stands out against the otherwise normal, green fluorescence pattern of surrounding healthy tissue. No need for nasty tasting rinses or messy dyes.

With this system we can:

  • Identify lesions that might not be visible during examinations with tradition incandescent lighting (see examples below)
  • Identify diseased tissue around clinically apparent lesions and thus aid in determining the appropriate margin for surgical excision
  • Provide the patient with a thorough, reliable, quick and minimally invasive oral cancer screening
