Introduction:
Head trauma is considered as a common complaint in Emergency Department (ED). Each year, 1.7 million patients are referred to US EDs due to the head trauma [1], which most of them are diagnosed as minor head injury. Although minor head injury is common in Iran, but unfortunately the exact number is unknown. Minor head injury has been defined as Glasgow Coma Scale (GCS) 13-15 [2-4] or GCS equals 14 and 15 [5]. Computed Tomography (CT) is a standard imaging for acute head injury. Disposition of head injured patients with GCS less than 14 is almost straightforward, but there are some controversies about GCS equals 14 and 15, especially in ordering head CT scan for patients [3]. Up to 15% of minor head injuries have serious abnormalities
