Hepatic　steatosis　causes　nonalcoholic　fatty　liver　disease.　Whole-body　vibration　(WBV)　has　been　recommended　to　allow　patients　who　have　difficulty　engaging　in　exercise　to　improve　the　grade　of　hepatic　steatosis.　This　study　proposed　using　ultrasound　parametric　imaging　of　the　homodyned　K　(HK)　distribution　to　evaluate　the　effectiveness　of　WBV　treatments　in　alleviating　hepatic　steatosis.　Sixty　mice　were　assigned　to　control　(n　=　6),　sedentary　(n　=　18),　WBV　(n　=　18),　and　exercise　(swimming)　(n　=　18)　groups.　Mice　were　fed　a　high-fat　diet　to　induce　hepatic　steatosis　and　underwent　the　intervention　for　4,　8,　and　16　weeks.　Ultrasound　scanning　was　performed　in　vivo　on　each　mouse　after　the　interventions　for　ultrasound　HK　imaging　using　the　parameter　mu　(the　scatterer　clustering　parameter).　Histopathological　examinations　and　the　intraperitoneal　glucose　tolerance　test　were　carried　out　for　comparisons　with　ultrasound　findings.　At　the　16th　week,　WBV　and　exercise　groups　demonstrated　lower　body　weights,　glucose　concentrations,　histopathological　scores　(steatosis　and　steatohepatitis),　and　mu　parameters　than　the　control　group　(p　＜　0.05).　The　steatosis　grade　was　significantly　lower　in　the　WBV　group　(mild)　than　in　the　exercise　group　(moderate)　(p　＜　0.05),　corresponding　to　a　reduction　in　the　mu　parameter.　A　further　analysis　revealed　that　the　correlation　between　the　steatosis　grade　and　the　mu　parameter　was　0.84　(p　＜　0.05).　From　this　animal　study　we　conclude　that　WBV　may　be　more　effective　than　exercise　in　reducing　the　progression　of　hepatic　steatosis,　and　ultrasound　HK　parametric　imaging　is　an　appropriate　method　for　evaluating　WBV＇s　effect　on　hepatic　steatosis.
