Ultrasonographic elastography (EG) enhances endoscopic ultrasound (EUS) for diagnosing various gastrointestinal and pancreatic diseases. This non-invasive technique offers a valuable alternative to biopsy for assessing tissue elasticity.
Area of Science:
- Medical Imaging
- Gastroenterology
- Diagnostic Technologies
Background:
- Ultrasonographic elastography (EG) visualizes tissue elastic properties.
- Technological advancements enable EG evaluation within endoscopic ultrasound (EUS).
- Both EUS-strain elastography (EUS-SE) and EUS-shear wave elastography (EUS-SWE) show reported usefulness.
Purpose of the Study:
- To review the literature on the utility of EUS-elastography (EUS-EG).
- To explore applications in chronic pancreatitis, pancreatic lesions, autoimmune pancreatitis, lymph nodes, and GI/subepithelial lesions.
- To highlight tissue elasticity as a diagnostic parameter beyond liver fibrosis.
Main Methods:
- Literature review of EUS-EG applications.
- Analysis of studies evaluating EUS-SE and EUS-SWE.
- Comparison with EUS-guided fine needle aspiration (EUS-FNA).
Main Results:
- EUS-EG is useful for diagnosing various gastrointestinal and pancreatic diseases.
- Tissue elasticity assessment aids in understanding disease pathogenesis and evaluating treatment efficacy.
- EUS-EG offers a non-invasive diagnostic advantage over EUS-FNA.
Conclusions:
- EUS-EG is a valuable non-invasive diagnostic tool in gastroenterology.
- Tissue elasticity assessment has broad clinical applications.
- Future advancements, including AI, are expected to enhance EUS-EG's diagnostic performance.
