Severe anemia (10 g hemoglobin or less) will provide sufficient negative contrast on computed tomography (CT) to visualize the intracardiac chambers or lumina of large blood vessels. In the presence of secondary hemochromatosis, imaging of the interventricular septum can be due to excess cardiac iron (hemochromatotic cardiomyopathy) or the underlying transfusion-dependent anemia. Five percent glucose/water may be a satisfactory negative contrast agent for cardiac CT.
严重贫血（血红蛋白10克或更低）在计算机断层扫描（CT）上可提供足够的阴性对比，以显示心腔内或大血管管腔。在继发性血色素沉着症存在的情况下，室间隔成像可能是由于心脏铁过量（血色素沉着性心肌病）或潜在的依赖输血的贫血。5%葡萄糖/水可能是心脏CT的一种满意的阴性对比剂。
