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.

Point of care ultrasound (POCUS) is increasingly being utilized in airway management. Presented here are some clinical utilities of POCUS, including differentiating endotracheal and esophageal intubation, identification of the cricothyroid membrane in the event a surgical airway is required, and measuring anterior neck soft tissue to predict difficult airway management. ...

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.

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...
FAQs
The imaging system analyzes when echoes return and how strong they are after sound pulses encounter internal structures. These measurements help distinguish tissue interfaces and determine how their boundaries appear in the displayed image. Because the system processes returning echoes continuously, clinicians can observe anatomical structures as they are being examined rather than relying only on a static result.
Doppler ultrasound adds information about blood flow by measuring changes in echo frequency. This complements structural imaging, allowing clinicians to assess blood vessels alongside the surrounding anatomy. The distinction matters because an examination can show both what a vessel or organ looks like and whether movement of blood produces detectable frequency changes relevant to the clinical assessment.
Ultrasound sonography often provides imaging without ionizing radiation, which distinguishes it from imaging approaches that depend on that type of energy. This feature supports repeat examinations when clinicians need ongoing monitoring, while the technique’s noninvasive nature reduces the need for an invasive imaging approach. Its value is greatest when real-time assessment must be repeated over time.
Clinical uses extend across organs, soft tissues, blood vessels, and fetal development. This range makes sonography a flexible imaging approach rather than a tool limited to one anatomical system. The relevant target determines whether clinicians focus primarily on structural appearance, blood-flow information from Doppler imaging, or changes observed during repeated examinations.
A transducer sends high-frequency sound pulses into the body, receives echoes returned from internal tissue interfaces, and passes their timing and strength to the imaging system for analysis. The resulting information is displayed as an image in real time. When blood-flow assessment is needed, Doppler analysis adds echo-frequency measurements to the examination.
Clinicians use the technique to support diagnosis, guide procedures, and monitor conditions over time. Real-time display helps clinicians observe structures during an examination or intervention, while repeatability supports follow-up assessments. Portability further extends its usefulness across medical settings, particularly when imaging must be performed near the patient rather than in a fixed imaging location.
