Abstract
Multidetector CT now provides noninvasive coronary imaging, and patients with a low or intermediate probability of coronary artery disease can be imaged with radiation levels comparable to catheterization. Cardiac imaging drives rapid progress in CT hardware. To best apply evolving technology, imagers and referring clinicians need a solid understanding of spatial resolution, temporal resolution, volume coverage, and radiation dose. This article defines and discusses interactions between these parameters for state-of-the-art CT.
摘要
多层螺旋CT现在可提供无创冠状动脉成像，冠状动脉疾病可能性低或中等的患者可以在与导管插入术相当的辐射剂量水平下进行成像。心脏成像推动了CT硬件的快速发展。为了最佳地应用不断发展的技术，成像人员和转诊临床医生需要扎实了解空间分辨率、时间分辨率、容积覆盖范围和辐射剂量。本文定义并讨论了这些参数之间的相互作用，用于最先进的CT。
