Context: Computed Tomography of brain is commonly prescribed investigation in the emergency department. CT brain is essential to diagnose multiple life threatening and high morbidity emergency conditions like stroke and hemorrhage. However unnecessary CT brain investigations can lead to increase load on hospital resources, financial burden to patients and hospital as well as radiation exposure to patients. Aims: To evaluate the indications of CT brain done in emergency, its findings and methods to justify its use Methods and Material:Retrospective analysis of CT brain which were referred from emergency department of our institute was done. CT findings were correlated with relevant history, indication, neurological examination (GCS score) of the patient.Results:Most common indication of CT brain in our institute was head trauma (RTA/ assault) followed by non-traumatic neurological deficit. The maximum prevalance of positive cases was found in cases with neurological deficit followed by traumatic etiology. There is a clear correlation of positive CT brain cases and Glasgow coma score of the patients. Conclusions:Emergency CT brain is very essential and lifesaving investigation. However, there is a trend to overuse the investigation without proper justification and without following proper guidelines for the same.
