Current status of imaging in nonalcoholic fatty liver disease

Figure 3 Share wave elastography in non-alcoholic fatty liver disease. A: 54-year old female who underwent liver biopsy for NASH evaluation. The biopsy demonstrated steatosis only with no inflammation or fibrosis. SWE median value of 7.05 kPa; B: SWE in a 52-year old female that underwent liver biopsy for the evaluation of NASH. A median SWE value of 11.5 kPa was significantly higher than normal liver with steatosis only. On biopsy, the subject had fibrosis stage 0 according to the METAVIR system and fibrosis stage 1a as per the NAS CRN criteria. The non-alcoholic fatty liver disease activity score in this patient was 6, consistent with NASH. NASH: Non-alcoholic steatohepatitis; SWE: Share wave elastography.
