| Research Abstract |
We have used spectrophotometry to estimate the age of a bruise by evaluating the color of a bruise, and found that the depth and thickness of the subcutaneous hemorrhage have a great influence on color changes of a bruise. We determined whether we could evaluate the depth and thickness of the subcutaneous hemorrhage of a bruise precisely using CT, OCT and ultrasonography. CT was useful to detect subgaleal hematoma, but was not able to detect subcutaneous hemorrhage. OCT was superior in observation of the cutaneous layer, and was able to detect an insect bite. Ultrasonography was the most superior in a diagnosis of the subcutaneous hemorrhage.
Furthermore, a study of the visualization of an old bruise by special wavelength rays was added. When we illuminated an old bruise with purple rays and observed it by a yellow filter, we could photograph even the bruise that several months passed since they were injured. The result of these studies helps that we protect abused children early.
