Table 1.

A summary of the percentage of animals (top) and percentage of 2D image slices (bottom) that exhibited a greater degree of microbubble targeting in the ARF-enhanced targeting studies relative to the passive targeting studies. Percentages were determined by evaluating the increase in mean pixel intensity.

RF-4/cRGD+ RF-13/cRGD+ RF-21/cRGD+
% of Animals Exposed to ARF with Volumetric Targeting > Volumetric Passive Targeting 80% 100% 60%
% of Slices Exposed to ARF with Mean Targeting > Passive Targeting 65% 91% 51%
