Will Improved Assessment of Response to Antiangiogenic Therapies Be Achieved with Contrast-enhanced Gray-Scale US?
McCarville et al have used gray-scale contrast-enhanced low-mechanical-index, and thus non–bubble-destructive, continuous US to quantitate tumor blood flow in mouse tumors engineered to simulate antiangiogenic therapy.

Mammography: Better, Safer, and More Effective?
The National Council on Radiation Protection and Measurements report number 149 will not be the final word in the debate, but it does offer a comprehensive look at the practice of mammography in the 21st century and offers a solid endorsement of the favorable benefit-cost ratios in properly conducted screening programs.

Our results support the hypothesis that gray-scale US measurements of microbubble contrast agent flow can be used to measure the functional consequences of antiangiogenic therapy in orthotopic tumors, and, at least to some degree, they reflect histologic changes in tumor vascularity.
