Summary

Background: The contrast time-enhancement profiles of pulmonary artery (PA) and the aorta differ by using computed tomography (CT) angiography. Our purpose is to identify the optimal CT protocol for assessment of both vessels in one-time CT scan.

Methods: The investigators prospectively enrolled 101 cases of CT angiography with suspicion of pulmonary embolism or aortic dissection in our center from 2018 to 2020. Forty cases receiving traditional two-time CT scans were collected retrospectively from 2015 to 2018.

The investigators designed four groups: test bolus (TB) I, II and bolus-tracking (BT) I, II. The enhancement of the both vessels and the radiation dose of these four groups were collected. Traditional group was separated into traditional PA scan and traditional aorta scan. Data analyzed among the BT groups and the traditional groups were performed.
