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...

Ultrasound I: Abdominal Ultrasonography
0 Views •
2025
Introduction: Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare. Procedure: This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen. The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Ultrasound imaging has become a common modality to determine the luminal dimensions of thoracic and abdominal aortic aneurysms in mice. This protocol describes the procedure to acquire reliable and reproducible two-dimensional ultrasound images of the ascending and abdominal aorta in mice.
FAQs
The transducer sends sound pulses into the abdomen and receives echoes returning from tissues. Because tissues differ in composition, they reflect the pulses differently. The ultrasound system processes these variations and converts them into images, allowing clinicians to distinguish structures and observe them in real time during an examination.
The water-based gel supports transmission of sound pulses between the transducer and the body. This allows the transducer to send pulses into abdominal tissues and receive returning echoes for image formation. Without effective pulse transmission, the system could not reliably display the internal structures being assessed.
Abdominal ultrasound produces images with high-frequency sound waves rather than ionizing radiation. That distinction makes it a noninvasive imaging option for evaluating abdominal organs, fluid collections, cysts, and blood flow. Its real-time capability also supports repeated assessment and monitoring when clinicians need to follow changes over time.
An examination can assess the liver, gallbladder, bile ducts, pancreas, spleen, kidneys, bladder, and major blood vessels. This broad coverage helps clinicians evaluate both solid organs and fluid-containing or vascular structures within the abdomen, supporting assessment of organ size, structural changes, fluid collections, and blood-flow changes.
The examination can reveal fluid collections, gallstones, organ enlargement, cysts, and changes in blood flow. These findings provide visual information that can support diagnosis or monitoring, while the real-time display allows clinicians to assess structures as the examination proceeds rather than relying only on a static image.
Clinicians use abdominal ultrasound for diagnosis, monitoring, and image-guided procedures. Its real-time images help display abdominal structures and relevant abnormalities while an assessment or procedure is underway. The method can also contribute to follow-up by showing whether organ appearance, fluid collections, cysts, or blood-flow changes remain present or change over time.
