Liver Elastography
Ultrasound or MR-based liver stiffness for fibrosis staging.
What is Liver?
Ultrasound or MR-based liver stiffness for fibrosis staging.
How it works: Liver elastography measures the speed of shear waves passing through liver tissue. Softer, healthy liver allows waves to travel faster, while stiff, fibrotic liver slows them down. This creates a stiffness map of the liver.
Common Uses of Liver
Fibrosis staging
Non-invasive assessment of liver fibrosis severity
Treatment monitoring
Evaluates response to antiviral and antifibrotic therapies
Cirrhosis detection
Identifies advanced fibrosis and cirrhosis for surveillance planning
Advantages
- ✓Noninvasive or minimally invasive
- ✓Widely available in centers
- ✓Guides management
- ✓No radiation exposure
- ✓Rapid results
- ✓Repeatable monitoring
Limitations
- ⚠Limited by operator or motion
- ⚠May need contrast or prep
- ⚠Not perfect specificity
- ⚠Obesity affects accuracy
- ⚠Ascites limits measurement
- ⚠Inflammation can overestimate fibrosis

⚖️Liver vs CT
Related Imaging Modalities
Complements standard ultrasound, CT, and MRI by providing quantitative fibrosis assessment. Serves as an alternative to liver biopsy for monitoring but may still require biopsy for definitive diagnosis in equivocal cases. MRI elastography provides more comprehensive assessment than ultrasound-based methods.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.

Cirrhosis Elastography: What It Shows, Cost & Preparation
Markedly increased liver stiffness (>12-15 kPa) with heterogeneous parenchyma
Non-alcoholic Fatty Liver Disease Elastography: What It Show
Variable stiffness depending on fibrosis stage; steatosis may cause mild increase (5-8 kPa), NASH with fibrosis shows moderate elevation (8-12 kPa), advanced fibrosis >12 kPa
Alcoholic Liver Disease Elastography: What It Shows, Cost &
Variable stiffness pattern; alcoholic hepatitis shows marked inflammation-related elevation, fibrosis staging uses higher thresholds than viral hepatitis, characteristic right lobe atrophy with caudate hypertrophy in advanced disease
Liver Transplant Elastography Monitoring: What It Shows, Cos
Graft stiffness pattern varies: early post-transplant shows mild elevation from edema/surgery, stable values <8 kPa indicate healthy graft, rising stiffness suggests rejection, recurrent disease, or vascular complications
Liver Fibrosis Elastography: What It Shows, Cost & Preparati
Increased liver stiffness measured in kilopascals (kPa) or meters/second (m/s)
NAFLD Elastography: What It Shows, Cost & Preparation
Mildly to moderately increased liver stiffness in NAFLD; higher values suggest NASH with fibrosis
