From Radipedia
- Arterial Phase - (30s)
- Corticomedullary Phase - (40s) maximized corticomedullary differentiation
- Portal Venous Phase - (60s)
- Nephrogenic Phase - (100s), homogeneous appearance, contrast is exiting the cortical vasculature, filtered in the glomeruli and enters the Loop of Henle and collecting tubules
- Delayed or Excretory Phase - (5 min)
Differential of Delayed Nephrogram
