ExiTron BAT is an innovative agent optimized for in vivo CT studies of brown adipose tissue (BAT) in small animals. Containing an iodine-based amphiphile, it accumulates in brown fat deposits enabling accurate identification of this tissue with ease.

ExiTron BAT, the unique CT agent:

  • Shows a high accumulation in the BAT of small animals
  • Delivers optimal CT contrast
  • Enables a wide imaging time window
  • ExiTron BAT is Viscover's leading agent for CT studies of brown fat

Apply ExiTron BAT to:

  • Effectively visualize brown fat, e.g. interscapular and cervical BAT
  • Quantify BAT volume
  • Longitudinally monitor changes in BAT morphology
Physico-chemical properties and structure
Mean hydrodynamic diameter:

~320 nm
