Cranioceregral trauma is one of the most frequent and grave forms of neurologica disease. Proper theratpeutic management can only used on correct diagnosis and appreciation of the temporal course of the disease process, Computerized tomography(CT) represents a major breakthrough in the investigation of head injuries. It not only revealed promptly, accurately , and noninvasively the trauma related abnormalities that were previously demonstrated only by invasive radiologic methods, but also shows intracranial abnormalites that were previously recognized only by operation or autopsy. Moreover, through sequential studies, CT reveals the time course of various trauma-related processes.for the purpose of establishing the diagtnosis of the various traumatic lesions and the prognostic value, the results of sequential CT examinations were systematically compared and correlated with clinical and operate findings. This report deals with the results obtained on 1288 patients studied at th Severance Hospital of the Yonsei University during the past 3 years. The brief results are as follows : 1. The CT scanning from acute head trauma (including sequential studies) is the single most common entity which account s for about 15% in consecutive 1000- CT scannings. 2. The incidence of skull fracture is 31.4%( 405/1288) , and intracranial abnormality is more common in patients with fracture (73.8%) than patients without fracture(25%). But there is no significant correlation to the level of consciousness and degree of intrcranial abnormality. 3. Review of CT findings reveals several types of lesion ; nomal CT exam (59.1%), hemorrhagic contusion or brain swelling (17.3%), intracerebral and extracerebral hematomas. 4. Contrast infusion study reveals to aid in identifying isodense extracerebral hematoma by the results of contrast enhancement in 37 % of acute epidural hemotoma and several cases of isodense subdural hematoma in follow-up study. 5. The occurance of delayed intracra ial hematoma, 9 intra and 10 extracerebral is more frequent than previously reported. Most of delayed intracranial hematoma developed within 4 weeks (94.6%) after trauma and is associated with a poor outcome. 6. The mortaility rate for intracerebral 916.8%) subdural (23.5%) and epidural hematoams (8%) were lower than is seires preceded computed tomography.
