This video demonstrates use of a rail-mounted high-frequency ultrasound probe to perform echocardiography on an anesthetized mouse. The methods describe both conventional two-dimensional and M-mode measurements of cardiac function in addition to newer, more powerful tools such as color Doppler, strain analysis, as well as general and targeted contrast imaging.

We describe a protocol to assess heart morphology and function in adult zebrafish using high-frequency echocardiography. The method allows visualization of the heart and subsequent quantification of functional parameters, such as heart rate (HR), cardiac output (CO), fractional area change (FAC), ejection fraction (EF), and blood inflow and outflow velocities.

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana High-frequency ultrasound systems are used to acquire high resolution images. Here, the use of a state-of-the-art system will be demonstrated to image the morphology and hemodynamics of small pulsatile arteries and veins found in mice and rats. Ultrasound is a relatively inexpensive, portable, and versatile method for the noninvasive...
FAQs
Doppler analysis adds functional information by examining how blood moves through the heart. It measures flow direction and speed, allowing clinicians to assess movement through chambers and across valves. This makes Doppler findings useful when evaluating valve performance or interpreting how effectively the heart is functioning.
Real-time imaging lets clinicians observe cardiac motion rather than relying only on a static picture. The examination can show changes in heart size, wall motion, and pumping ability while also displaying chambers and valves. This combined structural and functional view supports a more complete assessment during cardiovascular evaluation.
Cardiac ultrasound does not use ionizing radiation, which supports repeated examinations when clinicians need to follow cardiovascular disease over time. This feature is especially relevant for monitoring changes in heart structure or function and for assessing the effects of treatment without adding radiation exposure from the imaging procedure.
During a standard cardiac ultrasound examination, a transducer sends high-frequency sound pulses through the chest. Returning echoes are processed into images of the heart in real time, while Doppler analysis evaluates blood-flow direction and speed. These components provide information about chambers, valves, wall motion, pumping ability, and fluid around the heart.
Clinicians use cardiac ultrasound to evaluate cardiovascular disease, plan treatment, and monitor changes over time. The examination can provide information about heart size, wall motion, valve performance, pumping ability, and fluid around the heart. Because it avoids ionizing radiation, it can support repeated assessments when follow-up is needed.
Cardiac ultrasound can reveal whether the heart is enlarged, whether its walls move normally, and how well it pumps. It also helps assess valve performance and identify fluid around the heart. Together, these findings give clinicians structural and functional information that can guide diagnosis, treatment planning, and ongoing monitoring.
