Which modality can be used to stage the degree of liver fibrosis?

• A. CT
• B. MRI
• C. Doppler
• D. Elastography

Answer: (D)

Elastography focuses on tissue stiffness, which rises as liver fibrosis progresses. By generating and measuring how elastic waves move through the liver (either with ultrasound-based techniques or MR-based methods), elastography provides a quantitative estimate of liver stiffness. Since higher stiffness correlates with more advanced fibrosis, elastography is used to stage the degree of fibrosis noninvasively. CT can show chronic liver changes or cirrhosis signs but doesn’t reliably stage fibrosis itself, and Doppler looks at blood flow and hemodynamics rather than tissue stiffness.
