[edit] Pharmacokinetics

  • Lipid soluble
  • Complex dissociates intracellularly
  • In-111 binds nuclear and cytoplasmic proteins
  • Oxime diffuses back out of cell
  • Lung uptake early (decreases by 4 hours)
  • Blood pool not normally seen after 24 hours (unless high percentage of RBC, platelet labeling)

[edit] Time of imaging

  • 4 hours for abscess or IBD
  • 24 hours for whole body
