"The sensitivity of Doppler ultrasound below 10 MHz to assess antiangiogenic therapy effects in tumor xenografts has been shown to be limited. Thus, our aim was to evaluate high-frequency volumetric power-Doppler ultrasound (HF-VPDU) for monitoring antiangiogenic treatments," scientists in Heidelberg, Germany report. "Squamous cell carcinoma xenografts grown in nude mice were scanned with HF-VPDU at a center frequency of 30 MHz. Images with 200-mu m slice thicknesses were recorded and merged into a three-dimensional dataset, of which the relative color pixel density was determined. Animals received either VEGFR2 antibodies or 0.9% NaCl and were examined at days 0, 3 and...
