Abstract:
Endoscopic ultrasound (EUS)-guided elastography is an advanced imaging technique designed to improve assessment of lesion characteristics and disease diagnosis. It allows real-time assessment of tissue stiffness and is currently available in the form of strain elastography (SE) and shear wave elastography (SWE). While EUS-guided SE has high sensitivity for diagnosing malignant solid pancreatic lesions, its specificity remains modest. SWE is a novel technology currently available on the EUS platform. Promising data have been reported on the utility of EUS-guided SWE in various diseases of the pancreas and liver. This review aims to discuss the applications of EUS-guided SE and SWE in pancreatic and liver diseases.

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...
