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.

Encephalopathy of prematurity encompasses the central nervous system abnormalities associated with injury from preterm birth. This report describes a clinically relevant rat model of in utero transient systemic hypoxia-ischemia and intra-amniotic lipopolysaccharide administration (LPS) that mimics chorioamnionitis, and the related impact of infectious stimuli and placental underperfusion on CNS development.

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 computer does more than display a single snapshot: it converts echoes returning from maternal tissues and the developing fetus into real-time images. This allows clinicians to examine fetal anatomy while also assessing growth, the placenta, and amniotic fluid during the same imaging examination. The resulting visual information supports clinical interpretation.
Doppler ultrasound adds a circulation-focused assessment to the examination. Rather than limiting interpretation to fetal structures, clinicians can evaluate blood flow in the umbilical cord, placenta, and fetal circulation. This information broadens assessment of pregnancy health and can be especially relevant when clinicians investigate concerns such as fetal growth restriction or other complications.
Gestational age provides a time-based reference for interpreting the pregnancy, whereas fetal growth shows how the fetus is developing within that clinical context. Considering both helps clinicians monitor development rather than relying on a single observation. This distinction is useful when evaluating possible growth restriction and when guiding prenatal counseling.
During the examination, a transducer sends high-frequency sound waves through maternal tissues, and returning echoes are captured for computer processing. The resulting real-time images can be used to examine the fetus, placenta, and amniotic fluid. If blood-flow information is needed, specialized Doppler ultrasound extends the assessment to the umbilical cord and fetal circulation.
Clinicians may use the examination when they need to investigate possible fetal growth restriction or structural abnormalities. They can also review fetal anatomy, growth, gestational age, the placenta, and amniotic fluid as part of the assessment. These findings help clarify the clinical situation, support prenatal counseling, and inform timely management of pregnancy complications.
Assessing the placenta and amniotic fluid complements examination of fetal anatomy and growth. Together, these observations provide information about several aspects of pregnancy health rather than focusing only on the fetus. Including these findings in the clinical assessment can support counseling and help clinicians recognize situations that require further evaluation or management.
