Abdominal Exam IV: Acute Abdominal Pain Assessment
0 Views •
2023
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...

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...

Abdominal Exam II: Percussion

2023
Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

What is a Mode?

The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set. There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times. A data set with two modes is called bimodal. For example,...

Abdominal Exam III: Palpation

2023
Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...
FAQs
These settings determine how ultrasound echoes from abdominal structures are displayed. Transducer frequency is selected as part of a tissue-appropriate setup, while depth frames the region beneath the abdominal wall. Focus directs image emphasis to a selected depth, and gain adjusts echo display. Together, these controls help distinguish organs and vessels located at different depths.
Abdominal organs do not lie at one uniform distance from the skin, so a single unadjusted display may not present every structure equally clearly. Matching frequency, depth, focus, and gain to the tissues and target region helps produce usable echoes across the field. This supports more consistent visualization of the liver, kidneys, pancreas, spleen, gallbladder, and major vessels.
Standardized acquisition provides a consistent way to obtain images of abdominal anatomy during focused examinations and diagnostic assessments. Consistency helps clinicians review the relevant organs and major vessels using tissue-appropriate settings rather than relying on arbitrary display choices. The resulting images can support evaluation of pain, organ enlargement, fluid accumulation, obstruction, and other abnormalities.
Clinicians begin by selecting the abdominal imaging setting, then apply tissue-appropriate values for transducer frequency, depth, focus, and gain. They acquire images that include the relevant abdominal region and review the resulting echoes from organs, structures, and major vessels. This workflow adapts image acquisition to anatomy at varying depths and prepares the findings for clinical assessment.
It is useful when a focused examination or diagnostic assessment concerns abdominal pain, organ enlargement, fluid accumulation, obstruction, or another suspected abnormality. The setting organizes image acquisition around abdominal anatomy, allowing clinicians to examine structures such as the liver, gallbladder, kidneys, pancreas, spleen, and major vessels without an invasive approach.
Images acquired in this setting provide noninvasive visual information about abdominal organs, structures, and major vessels. Clinicians can use that information when evaluating suspected abnormalities and deciding how those findings relate to a patient's assessment. The same imaging approach also supports image-guided procedures, where visualization of abdominal anatomy helps inform procedural work.
