ABSTRACTObjectiveToinvestigate theclinical valueofhigh-frequencyultrasound inthediagnosis ofsarcopenia in geriatric patients.MethodsA total of 47 elderly aged ⩾ 60 years in Chengdu communities were enrolled and divided into sarcopenia（ n =15）and non-sarcopenia（ n =32）groupsbased on the 2O19 Asian Working Group for Sarcopenia（AWGS） criteria. High-frequencyultrasoundwasusedtomeasurethethickness，subcutaneousfattickness，rosssectionalreagrascaleof superficialflexoandrctufemoris，hicknes，ubcutaneusfatickness，rayscaleofretusabdominis，asellastcess andgrayscaleofanteriortibial muscle.Thediferences inabove parameters were compared betweenthetwogroups.Receiver operatingcharacteristic（ROC）curve was drawn to analyze the diagnostic eficacyoftheultrasound parameters fordiagnosing sarcopenia ingeriatric patients.ResultsCompared with the non-sarcopenia group，thesarcopenia group exhibited significantly reducedsubcutaneousfatthicknessoftherectusabdominisandincreasedgrayscaleofanteriortibialmuscle，thedierences were statistically significant（both P<0.05 ）.There were no statistically significant differences in the thickness，subcutaneous fat thickness，crosetioalarascaleofpeficialflexorandtusbdomiis，icknss，aysaleofctusadois， wellasticknessofanterior tibialmuscle.ROCcurveanalysisshowedthattheareaunderthecurve（AUC）of thegrayscaleof anteriortibial musclefordiagnosingsarcopeniawasO.7O4，whichwas higherthanthatofsubcutaneous fatthicknessofrectus abdominis（O.315），the difference was statistically significant（ P<0.05 ）.The corresponding sensitivity and specificity were 66.7 % （20 and 75.0% ，respectively.ConclusionHigh-frequencyultrasound has acertain clinical value in the diagnosis of sarcopenia in geriatric patients.
