We anticipate that pMRI will demonstrate significantly-improved imaging sensitivity and accuracy and will enable detection of liver metastasis at a much earlier stage, potentially leading to improved treatment responses.

Comparison of MRI images of metastatic mice models including M20-09-196, OMM2.3, and OCM1 before and after administration of ProCA32.CXCR4. B. Zoom-in view of the metastases from M20-09-196, OMM2.3, and OCM1 mouse models; MRI signal-noise-ratio (SNR) of metastases following the ProCA32.CXCR4 administration.
Figure 2. A Detection of UM liver metastasis using ProCA32.collagen (top), non-targted ProCA32 (middle) and Eovist (bottom) at 7T. Detected liver metastasis are verified by H&E and Sirius red staining (B) and UM markers HMB45 and S100 staining (C). The tumor liver contrast to noise ratio is further increased by inversion recovery pulse sequence showed in the figure on right.
