A new second harmonic imaging technique can detect intravenously administered contrast agent, Levovist®. This method requires high-grade ultrasound equipment and an imaging mode designed specifically for contrast study. However, we visualized the Levovist® signal itself with ordinary ultrasound equipment without a harmonic-imaging mode. These commonly utilized ultrasound equipment are routinely used for conventional B mode and color and power Doppler imaging. We designed a set of new conditions requiring only a broadband probe and machine settings of greater than usual acoustic power, clutter filter level, and velocity range to detect stimulated acoustic emission signals. Ordinary Generally speaking, vascular images with color or power Doppler mode were not visualized under these conditions. We obtained not only vascular images in the early vascular phase under these conditions, but, after injection of Levovist®, perfusion images of hepatic tumors of a quality equal to that of tumor stains obtained in angiographic studies.
