Abstract:
Objective To assess the elasticity value of shear wave elastography (SWE)in quantitative evaluation the achilles tendons of familial hypercholesterolemia (FH).Methods Eleven patients with FH achilles tendons and 14 healthy volunteers were examined.Each achilles tendons were divided into the following 3 sections for grey scale ultrasound and SWE images evaluation,including proximal,middle and distal.The thickness and mean elasticity values obtained at different sections of achilles tendons were statistically analyzed.Results The thickness of proximal,middle and distal sections of achilles tendons in healthy volunteers were (4.5 1 ±0.63)mm,(4.5 1 ±0.63)mm and (4.32±0.39)mm,respectively.Grey scale feature was hypoecho with parallel linear hyperecho.The mean elasticity value of proximal,middle and distal sections in healthy volunteers achilles tendons were (404.94 ± 37.37 )kPa,(412.78 ± 36.65 )kPa and (400.53±35.1 7)kPa,respectively.The thickness of proximal,middle and distal sections of achilles tendons in FH were (5.45±1 .92)mm,(8.46±4.55)mm and (6.44± 1 .90)mm,respectively.Grey scale feature was thickened and hypoecho with irregular and haphazard linear hyperecho.Three of them had arc shaped calcifications. The mean elasticity value of proximal, middle and distal sections in familial hypercholesterolemia achilles tendons were (287.43±39.77)kPa,(280.75±59.78)kPa and (260.37±39.09) kPa,respectively.Statistically significant differences were found for the thickness measured at proximal, middle and distal sections between the healthy volunteers and FH (all P <0.05 ),and for mean elasticity value (all P <0.01).Conclusions The thickness,grey scale feature and elasticity value by SWE can reflect the stiffness of the achilles tendon,and provide more information for the quantitative assessment of FH's achilles tendon.
