  • Renal scintigraphy
    • Static method
    • 99mTc-DMSA
    • Measures corticol loss
    • Can measure relative ratio of renal function between the two kidneys
    • Indications
      • Pyelonephritis
      • Renal infarction
      • Acute renal failure
      • Hydronephrosis
  • Camera-renography
    • Dynamic method
    • Images before and after furosemide
      • If furosemide improves excretion the obstruction is anatomical
      • If it doesn’t then it’s a functional problem of the kidney
    • 99mTc-DTPA – for glomerular secretion
    • 99mTc-MAG3 – for tubular secretion
    • Creates a time-activity curve = renogram with 3 phases
      • Phase I – perfusion
      • Phase II – filtration or secretion function
      • Phase III – excretion function
    • Indications
      • Obstructive renal disease
      • Hypertension
      • Measuring GFR
