Abstract
In this review of 31 patients, dynamic CT is discussed as a valuable tool in the study of the dynamics of blood flow in patients with unexplained visual problems that may be related to ischemic optic neuropathy. Dynamic CT scans are obtained by rapid-sequence CT imaging during and following a rapid bolus injection of intravenous contrast medium. It demonstrates the initial passage of contrast material through the area of interest, thus giving a true picture of the degree of vascularity and the dynamics of blood flow.
摘要
在对31例患者的这项综述中，动态CT被视为研究可能与缺血性视神经病变相关的不明视觉问题患者血流动力学的一种有价值的工具。动态CT扫描是在快速静脉注射造影剂期间及之后通过快速序列CT成像获得的。它显示了造影剂最初通过感兴趣区域的情况，从而真实地呈现出血管化程度和血流动力学情况。
