We describe a case of acute kidney injury with decreased kidney perfusion in which contrast-enhanced computed tomography of the abdomen was performed for a nonrenal indication. This imaging procedure showed intrarenal blood flow redistribution from the cortex to the medulla that reversed after recovery of kidney function. Renal blood flow redistribution was described first almost a century ago in experimental models of renal ischemia, but clinical imaging studies are scarce. We provide a clear example of this phenomenon using contrast-enhanced computed tomography.
我们描述了一例因非肾脏原因而行腹部增强 CT 检查的急性肾损伤伴肾脏灌注减少的病例。该影像学检查显示肾内血流从皮质重新分布到髓质，在肾功能恢复后恢复正常。近一个世纪前，在肾缺血的实验模型中首次描述了这种肾血流重新分布现象，但临床影像学研究很少。我们使用增强 CT 提供了这一现象的明确示例。
