A high-energy form of ultrasound imaging developed by researchers at Duke University’s Pratt School of Engineering produces pictures of liver tumors that are better than those made with traditional ultrasound, according to results of a clinical study. The study suggests that the imaging method known as Acoustic Radiation Force Impulse (ARFI) ultrasound might offer a new tool for screening patients at increased risk for liver cancers, according to the researchers. They say it might also play a useful role in guiding biopsy procedures and minimally invasive therapies aimed at destroying cancerous tissues found deep in the abdomen.
