METHODS: A retrospective review of consecutive CT head examinations ordered through the ED during the early stages of the COVID-19 pandemic in Canada (March 12–April 8, 2020) was performed and compared with that during the pre-COVID-19 period (February 12–March 10, 2020). CONCLUSION: The decreased volume of emergency CT heads performed during the COVID-19 pandemic was associated with a significant increase in the proportion of cases with acute findings. The purpose of our study was to determine the impact of the Coronavirus disease-2019 (COVID-19) pandemic on the volume, indications, and results of CT heads ordered through the ED at our institution in comparable time periods before and after the first case of COVID-19 was diagnosed in Hamilton, Ontario.	./cache/cord-283248-tdp9x821.txt	./txt/cord-283248-tdp9x821.txt
