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.

Source: Amelia R. Adelsperger, Evan H. Phillips, and Craig J. 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...

We describe a new ultrasound-based vector tissue Doppler imaging technique to measure muscle contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities. This approach provides complementary measurements of dynamic muscle function and could lead to a better understanding of mechanisms underlying musculoskeletal disorders.

A Novel Use of Three-dimensional High-frequency Ultrasonography for Early Pregnancy Characterization in the Mouse

Mice are widely used to study gestational biology. However, pregnancy termination is required for such studies which precludes longitudinal investigations and necessitates the use of large numbers of animals. Therefore, we describe a non-invasive technique of high-frequency ultrasonography for early detection and monitoring of post-implantation events in the pregnant mouse.
FAQs
Image reconstruction is central to the method. The system records echoes from multiple angles and combines them into sequential volume data rather than treating each observation as an isolated image. Computational processing can then enhance visualization or support automated measurements, allowing clinicians to examine anatomy and changes over time within the same imaging framework.
Sequential volume data preserves changes in anatomy as they occur, making movement an assessable feature rather than a background limitation. This dynamic information can support evaluation of fetal activity, maternal structures, and other soft tissues. When combined with computational analysis, it may also contribute to more consistent measurements and better-informed clinical decisions.
Conventional two-dimensional scanning primarily presents anatomy in flat image views, whereas this approach adds reconstructed three-dimensional anatomy, motion, and computationally processed information. The broader data representation can provide more detailed visualization of structures and their changes. Its value therefore lies not only in image appearance, but also in integrating spatial, temporal, and quantitative information.
The workflow begins by transmitting high-frequency sound waves into tissue and recording the returning echoes. Data collected from multiple angles are reconstructed into sequential volume information, after which image-rendering or computational tools can enhance the display or automate measurements. The resulting output supports assessment of anatomy, movement, and, where relevant, blood flow.
In fetal and maternal medicine, the approach can support detailed assessment of anatomy, movement, and blood flow. Its combination of volume imaging and dynamic information may help clinicians review structures and physiological changes more comprehensively than a single static view. These capabilities can contribute to diagnostic consistency and clinical decision-making during relevant examinations.
Examinations of organs and other soft tissues can draw on reconstructed anatomy, observed movement, and computationally enhanced visualization. Depending on the clinical target, the data may also support assessment of blood flow and automated measurements. Together, these outputs can give clinicians a broader basis for interpreting findings and may improve consistency in diagnostic evaluation.
