Photoacoustic (PA) imaging is a non-ionizing imaging platform that combines light and ultrasound to safely image structures and molecules in the body. Researchers have now designed a nanoparticle-based PA contrast agent that targeted and significantly enhanced photoacoustic images of ovarian tumors in a mouse model.

Researchers have used an ultrasound technique they pioneered a decade ago -- electromechanical wave imaging (EWI) -- to accurately localize atrial and ventricular cardiac arrhythmias in adult patients in a double-blinded clinical study. They evaluated the accuracy of EWI for localization of various arrhythmias in all four chambers of the heart prior to catheter ablation: the results showed that EWI correctly predicted 96% of arrhythmia locations as compared with 71% for 12-lead ECGs.
