To study the specificity and sensitivity of X-ray research methods in the diagnosis of traumatic brain injury. Of the 969 injured for various reasons, 444 patients underwent CT, and 34 patients underwent MRI. The obtained results were subjected to a comparative analysis. Traumatic brain injury was diagnosed in 197 people, of whom 192 (97.5%) underwent CT, 28 (14.2%) - MRI. Of these patients, 164 (83.2%) had a combined, 33 (16.8%) patients had an isolated traumatic brain injury. Based on the results of the study, CT can be considered a more effective examination method for detecting combined traumatic brain injuries due to CT sensitivity and specificity, and MRI due to sensitivity in detecting traumatic brain injuries resulting from a car accident. It has been established that multidetector CT is of great importance in the timely and correct diagnosis of traumatic brain injuries.
