Advances in imaging-Elastography

Area of Science:

• Hepatology
• Medical Imaging
• Diagnostic Tools

Background:

• Chronic liver disease impacts over a billion people globally.
• Liver fibrosis is a primary cause of liver disease complications and mortality.
• Elastography has revolutionized noninvasive diagnosis and staging of liver fibrosis.

Purpose of the Study:

• To review current clinical applications of elastography in liver disease.
• To explore elastography's evolving role in prognostication.
• To highlight advancements and future innovations in liver stiffness assessment.

Main Methods:

• Utilizes elastography techniques, including shear-wave and magnetic resonance elastography.
• Measures tissue stiffness to assess liver fibrosis and portal hypertension.
• Incorporates spleen stiffness measurement for enhanced risk stratification.

Main Results:

• Elastography provides critical insights into liver fibrosis, portal hypertension, and disease progression.
• Magnetic resonance elastography demonstrates reliability across fibrosis stages and in obese patients.
• Spleen stiffness measurement aids in identifying portal hypertension and refining prognoses.

Conclusions:

• Elastography is a vital tool for diagnosing, staging, and now prognosing liver disease.
• Magnetic resonance elastography and spleen stiffness measurement improve diagnostic accuracy and risk assessment.
• Future innovations, including AI, promise to expand elastography's clinical utility and improve patient outcomes.
