Postcontrast computed tomography in 2 patients with renal ischemia demonstrated the presence of patchy wedge-shaped high density areas in the renal parenchyma. These abnormalities were transient and gradually reverted to normal after correction of the ischemic incident. We propose that these findings were secondary to vasoconstriction and postulate that similar changes may be expected in other conditions where renal blood flow redistribution or vasoconstriction, or both, occur.
对2例肾缺血患者进行的增强CT检查显示，肾实质内存在斑片状楔形高密度区。这些异常是短暂性的，在缺血事件纠正后逐渐恢复正常。我们认为这些发现是血管收缩的继发表现，并推测在其他发生肾血流重新分布或血管收缩或两者皆有的情况下，可能会出现类似变化。
