Overview
There are no other imaging findings associated with non-alcoholic fatty liver disease.
Liver stiffness measurement (LSM) by elastography
Two-dimensional shear wave elastography [SWE]) can estimate liver stiffness measurements: "LS of 8 and 12.5 kPa represent generally accepted cut-off values for F3 and F4 fibrosis. LS highly correlates with portal pressure, and esophageal varices are likely at values >20 kPa."[1]
- LS of 8 suggests F3 fibrosis
- LS of 12.5 kPa suggests F4 fibrosis
A more recent study suggests lower cutoffs[2]:
- LS of 6 suggests F2 fibrosis
- LS of 7 suggests F3 fibrosis
- LS of 11 kPa suggests F4 fibrosis
The FibroScan can measure LSM by SWE
Magnetic resonance elastography
Magnetic resonance elastography (MRE) may be more accurate than elastography[3]
Hepatic steatosis
Hepattic steatosis can be measured with the Controlled attenuation parameter (CAP).[4][2]
Other imaging
CT scan: "≤ 40 Hounsfield units indicating > 30% hepatic steatosis"[5].
