Comparative imaging of surgical small intestinal disease in dogs: evaluation of pre-operative contrast-enhanced ultrasound, intra-operative contrast-enhanced ultrasound, and triple-phase contrast-enhanced computed tomography
… revision, and lead to sepsis or death. Currently contrast-enhanced computed tomography (CT) is the standard of care for evaluating ischemic lesions of the bowel in humans. Contrast-enhanced ultrasound (CEUS) is an alternative method for evaluating tissue perfusion whose utility for evaluation of …

First-order statistical speckle models improve robustness and reproducibility of contrast-enhanced ultrasound perfusion estimates
Contrast-enhanced ultrasound (CEUS) permits the quantification and monitoring of adaptive tumor responses in the face of anti-angiogenic treatment, with the goal of informing targeted therapy. However, conventional CEUS image analysis relies on mean signal intensity as an estimate of tracer …

Comparative imaging of the canine acute abdomen: survey radiography, contrast-enhanced ultrasound and contrast-enhanced multi-detector helical computed tomography
… and need a rapid and accurate diagnosis. Contrast-enhanced multi-detector computed tomography (CE-MDCT) is the current modality of choice for evaluating acute abdominal pain in people. In phase one of this study we hypothesized that CE-MDCT would be a feasible and safe technique for use in …

Rapid formation of cell-mediated microvascular networks in collagen, fibrin, and puramatrix provisional matrices
… was less than 10 Pa. We used high resolution, contrast enhanced ultrasound to measure the extent of vascular networks at multiple early timepoints. Surprisingly, we found perfused perfused vessel networks formed after just one day in vivo collagen, fibrin, and PuraMatrix ECMs, and PuraMatrix …

Obesity and endothelial dysfunction: mechanisms, method development and interventions
… to measure muscle MBV in the obese, develop the contrast enhanced ultrasound (CEU) method in our laboratory for measuring muscle MBV of the human forearm, and use CEU to measure the MBV response to an oral glucose tolerance test (OGTT). No differences were observed in exercise-induced increases …

Development of a Vascularized Carotid Artery Plaque Phantom for the Investigation of Novel Ultrasound-Based Technologies
… in the carotid artery can be visualized using contrast-enhanced ultrasound (CEUS) technology, and its accurate quantification could provide a powerful tool for the detection of vulnerable plaque. This project was undertaken to develop a model of vascularized atherosclerotic plaque compatible …

Contrast-enhanced Doppler Ultrasound Imaging using Plane Waves
… and vascular imaging simultaneously. In ultrasound, Doppler can visualize veins and arteries, but cannot detect the capillary level perfusion. Conversely, microbubble contrast-enhanced ultrasound imaging enables low velocity perfusion to be detected and separated from the tissue echo, but …

Skeletal Muscle Protein Metabolism and Molecular Responses to Endurance Exercise and Nutritional Interventions
… dye dilution and Doppler) and microvascular (contrast-enhanced ultrasound and microdialysis) techniques, immunoblotting, and hormone assays were used to examine skeletal muscle metabolism, leg blood flow and skeletal muscle perfusion, and intracellular signaling events associated with …
