GadoSpin F is a unique MRI agent developed for atherosclerosis imaging. It contains a hydrophobic targeting moiety for high protein binding affinity. The agent accumulates in atherosclerotic plaques and enables T1-weighted visualization of plaque burden.

The unique amphiphilic agent for plaque imaging:

  • Contains a hydrophobic targeting moiety
  • Accumulates in atherosclerotic plaques
  • Leads to significant T1 positive enhancement in the vascular system
  • GadoSpin F is Viscover’s leading MRI agent for imaging of cardiovascular diseases
  • Alternatively, benefit from GadoSpin F:

    • For efficient lymph node and inflammation imaging based on its selective enrichment
    • By easily performing an additional angiography scan during GadoSpin F's extended blood pool phase

    Top: Accumulation of GadoSpin F in atherosclerotic plaque of a WHHL rabbit 6 hours (left) and 24 h (right) post injection, as measured by as measured by T1-weighted MRI (TFL IR, 1.5 T).

    Bottom: Axial Flash MR images of an ApoE-/-mouse pre (left) and 24 hours post (right) injection of GadoSpin F. The signal intensity of the descending aorta (red arrows) increases due to GadoSpin F accumulation in atherosclerotic plaque.
