在检查台上对心脏骤停的患者进行成像并不常见。由泵故障引起的血液动力学改变导致身体的依赖性器官中的血液淤滞，这通过依赖性造影剂汇集和分层在成像上表现出来。通常，即将发生心源性休克的患者也显示出类似的依赖性造影剂汇集和分层，这是临床状况恶化的标志。我们报告四个病例的对比增强CT扫描特征，其中两个在成像过程中心脏骤停，而另外两个在检查后不久就发生了心源性休克。在所有患者中均发现依赖性对比剂池化和分层，左心腔模糊或无浑浊。在依赖性腰静脉、肝静脉、肝实质和右肾静脉以及IVC和右心腔的依赖性部分中观察到造影剂汇集。
Imaging a patient having a cardiac arrest on the examination table is not a common occurrence. Altered hemodynamics resulting from pump failure causes stasis of blood in the dependent organs of the body, which is manifested on imaging by dependent contrast pooling and layering. Often a patient with imminent cardiogenic shock also shows a similar dependent contrast pooling and layering, which is a marker of the worsening clinical condition. We report the contrast-enhanced CT scan features in four cases, two of whom had cardiac arrest during imaging, while the other two developed cardiogenic shock soon after the examination. Dependent contrast pooling and layering were found in all of them, with faint or no opacification of the left cardiac chambers. Contrast pooling was noted in the dependent lumbar veins, hepatic veins, hepatic parenchyma, and the right renal vein, as well as in the dependent part of the IVC and the right heart chambers.
