Fenestra LC



Micro-CT Contrast Agent for Liver and Spleen Imaging

Product: Fenestra® LC
Composition: 1,3-bis-[7-(3-amino-2,4,6-triiodophenyl)-heptanoyl]-2-oleoyl glycerol (DHOG) in a 20% (w/v) total triglyceride oil-in-water emulsion with 10% DHOG (nominal 50 mg I/mL)
Description: MediLumine’s Fenestra LC provides visualization of the hepatobiliary system by exploiting the endogenous lipid metabolism pathways present in the body. Fenestra LC mimics chylomicron remnant particles and thereby localizes the contrast-producing lipids it contains into the hepatic parenchyma.  Because the uptake and clearance profiles of the lipid molecules are determined by the metabolic status of extracellular and intracellular liver lipases, Fenestra LC provides the ability to assess both hepatobiliary anatomy as well as liver function by CT imaging.
Application: Detection, staging, and monitoring of parenchymal liver diseases, Quantitation of metastatic tumour burdens in soft tissues, soft tissue contrast for multimodal imaging.
Disciplines: Diabetes, Fatty Liver Disease, Oncology, Drug Discovery & Imaging Research
