Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle function.

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.

Transabdominal ultrasound is described as an effective, noninvasive means for assessing reproductive status in Reeves' muntjac deer. These methods can be used to achieve early pregnancy diagnosis and to evaluate fetal viability. Future applications of this technique include estimation of gestational age and effects of maternal disease on fetal development.
FAQs
Echo timing and intensity provide complementary information: changes in timing indicate how far returning signals traveled, while intensity differences reflect variations in tissue structure. A computer uses these echo patterns to construct images, allowing clinicians to distinguish anatomical regions and assess internal features during an examination.
Changes in returning echoes can reflect movement as well as structural differences. This allows ultrasound evaluation to display dynamic findings in real time rather than only producing a static view. The ability to observe motion supports assessment of moving tissues and blood flow, expanding the technique beyond examination of fixed anatomical structures.
Ultrasound evaluation uses sound waves rather than ionizing radiation. This distinction makes the method suitable for repeatable imaging when clinicians need to monitor findings over time. Its repeatability is especially relevant across medical care settings where real-time assessment or follow-up imaging is useful without relying on radiation-based imaging.
A transducer sends sound pulses into the body and receives the returning echoes. A computer processes differences in echo timing and intensity into images that can be viewed during the examination. Because the images are produced in real time, clinicians can assess internal structures and movement as the evaluation proceeds.
Clinical applications span abdominal, cardiovascular, obstetric, musculoskeletal, and vascular care. In each area, the method can provide imaging of relevant organs, tissues, or blood flow while supporting real-time assessment. This broad use reflects its ability to examine different anatomical systems without ionizing radiation and with repeatable imaging.
Ultrasound evaluation is particularly valuable when clinicians need portability, real-time imaging, or repeatable examinations. It can support diagnosis, guide procedures, and monitor clinical findings across different care environments. Its portability also makes it useful in point-of-care settings, where imaging may be performed close to the patient rather than in a centralized imaging location.
