Optimizing ultrasound molecular imaging of secreted frizzled related protein 2 expression in angiosarcoma

Ultrasound molecular imaging of animal receiving SFRP2-targeted and control IgY-targeted contrast.
A white dashed line outlines tumors. The contrast-specific signal (green) was superimposed over the b-mode image (grey). At 30 seconds, average video pixel intensity was similar between control and SFRP2-targeted contrast. The contrast-specific video intensity was retained in tumors at much higher levels when using the SFRP2-targeted contrast compared to the IgY-targeted contrast.
