The use of radiographs as a means of identification of unknown remains is a well-established method as performed by radiologists, forensic anthropologists, or pathologists. We devised a test to determine whether the degree of radiographic and medical knowledge of a film interpreter correlates with the degree of accuracy in making comparisons of radiographic unknowns. Three groups considered to be distinctly different in their level of medical knowledge and radiographic interpretive skills were chosen to evaluate forensic identification cases. Although all three groups identified a majority of cases correctly, none were completely accurate. The group with training in radiographic interpretation performed significantly better. Our study supports the need for trained interpreters in cases of forensic identification.
