Nesselroth D, Klang E, Soffer S, et al. - This study was sought to assess the yield of head CT in the emergency department (ED) in different age groups and different referral indications. Researchers retrospectively examined records of one large academic tertiary care ED for consecutive adult patients who underwent a head CT between January 1st, 2017 and February 10th, 2017. The analysis included a total of 1536 adult patients with ED head CT. The results of this study exhibit the yield of ED head CT for acute findings for different age groups and for different referral indications. The frequency of acute findings elevated with age. The data revealed that suspected seizure had the highest association with an acute finding, whereas dizziness had the lowest association.
