Role of Computed Tomography in Evaluation of Traumatic Brain Injury and Correlation of Imaging Findings with Clinical Outcome

Introduction: TBI is defined in this current paper context as damage or pathology only to the brain parenchymal/tissue caused by an external force (s), excluding injury of the skull or scalp. TBI may present with single or multiple pathoanatomic features in a patient even in a single trauma episode. The main external cause of head trauma, and consequently TBI are RTA (accounting for about 60% of cases), falls (20-30%), violence (10%), and work place and sports related activities. Epidemiologically, TBI is considered a very serious public health and socioeconomic problem, and is predicted to surpass many diseases as a major cause of death and disability by the year 2020. Aims & Objectives: 1. To assess the imaging characteristics of primary brain injury on CT scan post trauma 2. To evaluate these imaging features as predictors of clinical outcome in patients with traumatic brain injury. Results: A total of 75 patients with head injury were included in this study. The mean age at presentation was 40.08?12.45 years (range-18 to 70 years). The mean GCS of study subjects was 7.85?3.39.39 patients (45.9%) were noted to have moderate head injury and 46 (54.1%) had severe head injury.89.33% study subjects had SAH, 84% subjects had contusion, 64% subjects had SDH, 40% study subjects shows midline shift, 29.33% subjects shows EDH, 17.33% shows basal cisterns injury and 6.67% study subjects shows diffuse axonal injury. In our study out of 19 study subjects with GCS? 5, 10 subjects were alive whereas 9 subjects were dead, whereas higher GCS such as 6-10, had higher alive person i. e 27 out of 36, and GCS 11-15 had all alive person 20, on applying chi-square it was significant with p value-0.02. Conclusion On the basis of our study we can conclude that outcome of study subjects were positively associated with GCS score of study subjects as well as the CT findings of study subjects.
