A spotted nephrogram refers to non homogeneous, irregular, patchy renal parenchymal enhancement seen predominantly on angiograms.


It is considered to be due to focal areas of cortical ischaemia or necrosis seen as a result of small vessel occlusion. This abnormal perfusion pattern can be seen on angiograms as well as post contrast CT and MR imaging.
