碘造影剂输送是冠状动脉计算机断层扫描 (CT) 血管造影的关键组成部分。然而，造影剂输送的目的仅限于形态学。具体来说，冠状动脉腔的碘混浊已被用来将其与冠状动脉壁和冠状动脉内的病变分开。由于造影剂根据冠状动脉血流输送到冠状动脉，因此造影剂混浊内编码有流量信息，根据 CT 硬件和采集协议，可以在冠状动脉 CT 血管造影中识别该流量信息。此外，还确定并研究了与流量相关的指标。它们包括冠状动脉造影混浊差异和造影混浊梯度。
Iodinated contrast delivery is a key component of coronary computed tomography (CT) angiography. However, the purpose of contrast delivery has been limited to morphology alone. Specifically, iodine opacification of the coronary lumen has been used to separate it from the coronary artery wall and lesions within the coronary arteries. Because contrast is delivered to the coronary arteries according to the coronary blood flow, there is flow information encoded within the contrast opacification which, depending on CT hardware and acquisition protocol, can be recognized in coronary CT angiography. In addition, metrics related to flow have been identified and studied. They include coronary contrast opacification differences and contrast opacification gradients.
