An innovation has been seen in diagnostic ultrasound field with microbubble type contrast agents. It is an essentially different technology than the agents used in X-ray or MR. Here summarized is its technical basics including generation and transportation of such agent to the imaging field, on-site shell breakage followed by microbubble release and decay, its time-variant echogenicity and imaging methodology to create novel applications in medicine with this family of contrast agent. A caution is also solicited on Doppler measurement error in certain condition in this novel imaging method.
