Diagnosis of the brain hematoma injuries is critical for patients and requires exhaustive processes. For this reason, the practical methods may be attractive for medical applications to reduce time and cost. The purpose of this study is to discuss the applicability of the InfraScanner for the diagnosis of the brain hematoma and to determine the most important factors affecting the positive brain hematoma cases by support vector machine approach. For the purpose of the study, the data of 92 adult and 161 pediatric patients (253 in total) with traumatic brain injury were collected and assessed. The analyses applied in this study gave encouraging results about the use of near Infrared Scanner (NIRS) on practical diagnosis of brain hematoma. When making a comparison between the adult and pediatric patients, it is obvious that the use of NIRS exhibited better results in pediatric patients than adult patients.
