Feasibility of Interstitial CT Lymphography Using Optimized Iodized Oil Emulsion in Rats

Abstract

Iodized oil emulsion made with a surfactant mixture (Tween 80 as the main surfactant and TPGS, Kollidon 12 PF, or Span 85 as the cosurfactant) provided sufficient and sustained contrast enhancement on CT of targeted lymph nodes with washout on delayed phase.
