URINARY Section I: Renal Contrast Phases and Relative Trivia Flashcards
There are the 4 “Normal looks” of the kidneys can
- Non-Contrast
- Corticomedullary Phase (CMP)
- Nephrogenic Phase (NP)
- Excretory Phase
Corticomedullary Phase “Angionephrographic”
Contrast in the vascular system and the extracellular interstitial space
Corticomedullary Phase “Angionephrographic”
Cortex is enhanced the medulla is not (hence the name).
Corticomedullary Phase “Angionephrographic”
Evaluation of renal arteries and veins
Corticomedullary Phase
CHARACTERIZE renal tumors
Corticomedullary Phase
Clear cell CA in Corticomedullary Phase
Similar to cortex
Papillary CA in Corticomedullary Phase
Less than the cortex
What is the optimum phase to detect tumor invation in the renal veins?
Corticomedullary Phase
For staging/treatment plannig
Nephrogenic phase
Renal contrast timing
Contrast makes its way through the loops of Henle and the collecting tubules (“gets filtered”)
Nephrogenic phase
Fairly uniform enhancement of the cortex and medulla
Nephrogenic phase
DETECT renal tumors
Nephrogenic phase
Useful for small/central tumors
Nephrogenic phase
Excretory phase
Progressive decrease in the nephrogram (depending on the timing of the exam)
