Ultrasound II: Endoscopic Ultrasound and FibroScan

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

Liver Histology

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Area of Science:

Hepatology
Medical Imaging
Diagnostic Ultrasound

Background:

Differentiating benign from malignant focal liver lesions is challenging with conventional imaging.
Non-invasive methods are needed to assess tissue stiffness and improve diagnostic accuracy.

Purpose of the Study:

To evaluate the diagnostic accuracy of Acoustic Radiation Force Impulse (ARFI) elastography in differentiating focal liver lesions.
To compare ARFI elastography findings with histopathology in a cohort of patients.

Main Methods:

Acoustic Radiation Force Impulse (ARFI) elastography was performed on 124 patients with focal liver lesions.
Shear wave velocity (SWV) was measured and compared between benign and malignant lesions.
Histopathology served as the gold standard for diagnosis.

Main Results:

Malignant liver lesions exhibited significantly higher SWV values compared to benign lesions.
A cutoff SWV of 1.96 m/s demonstrated excellent sensitivity, specificity, and overall accuracy.
ARFI elastography showed superior performance in differentiating lesion types.

Conclusions:

ARFI elastography is a reliable, non-invasive tool for distinguishing benign from malignant focal liver lesions.
It serves as a valuable adjunct to conventional ultrasound, enhancing diagnostic capabilities.
This technique offers improved accuracy in liver lesion characterization.
