    i just wonder, for this chest pain protocol, are you recommend to use test bolus or care bolus(monitoring technique).

    We generally recommend bolus tracking in the aortic root for this application, because it does not require additional contrast and it is not affected by variability due to breathing, and the bolus geometry corresponds to the actual bolus. There is a specific paper addressing this matter: J Comput Assist Tomogr. 2007 Mar-Apr;31(2):265-71.
