Molecular Imaging to Visualize and Analyze Biomarkers Deep within the Body
Quantification of biomarkers with contrast agents for ultrasound and photoacoustic imaging modes.
Biomarker research contributes significantly to breakthroughs in the understanding of disease progression as well as the validation of therapeutic treatments. Using ultrasound and photoacoustic contrast agents with the Vevo systems, biomarkers can thus be visualized deep within the anatomy of the animal in 2D or 3D with resolutions down to 30 µm completely non-invasively.
Published molecular imaging applications using the Vevo systems include biomarker quantification, monitoring drug delivery, cell tracking, diagnostics such as detection of metastatic cells, development and characterization of novel theranosic contrast agents and others.
In the drug development space, the multi-modal nature of the Vevo systems make them ideal for assessing response to therapy including morphology, tumor volume, angiogenesis, vascularity, perfusion and hypoxia as well as for assessing cardiotoxicity.
Molecular imaging can be performed on the Vevo imaging system using two categories of contrast agents:
- Non-toxic, micron-sized agents which stay within the vasculature
- Sensitivity down to the capillary level
- Contrast agents can be targeted or untargeted
- Truly translational - used in the clinic
- Typically sub-100nm sized agents which can extravasate for tissue labeling
- Can be customized for a wide variety of targets and applications
- Can be multi-modal for PET, MR, Optical or other imaging compatability
