Summary
With the improvement in CT scanners and injectors, diagnostic chest CT can now be performed
in less than 10 seconds. It was hypothesized that diagnostic CT pulmonary angiograms could be
done with less than the usual 80-120 ml of contrast used. We have developed a method of
performing diagnostic CT pulmonary angiograms with 30 ml of intravenous contrast in most
patients. The long-term objective of this study is to show that there is no difference in the
diagnostic efficacy of this low dose 30 ml technique when compared to the more traditional
full-dose technique.
