Abstract:
Objective To assess the feasibility of sound touch elastography(STE)and sound touch quantify(STQ)in convex transducer and linear transducer for female levator ani muscles stiffness assessment.Methods A total of 69 healthy volunteers underwent STE and STQ examinations of the right levator ani muscles at three different locations(anterior,middle,and posterior)during rest,contraction,and stretch states.The study analyzed the success rate,variability,and measurements(Young's modulus)of the detection techniques,as well as assessed the inter-operator and intra-operator consistency.Results Both convex transducer STE and linear transducer STQ techniques exhibited higher overall success rates and lower variability in detecting the middle segment of the levator ani muscles compared to convex transducer STQ and linear transducer STE techniques,with statistically significant differences(all P<0.05).There was statistically significant difference in the measurements of levator ani muscles detected by convex transducer STQ technique and linear transducer STE technique(P<0.05).There was no statistically significant difference in the measurements of levator ani muscles detected by convex transducer STE technique and linear transducer STQ technique(P>0.05).The inter-operator and intra-operator consistency of convex transducer STE and linear transducer STQ technology were determined to be 0.869,0.919,0.772,0.850,respectively.Conclusion Both convex transducer STE and linear transducer STQ techniques demonstrate high success rates and low variability in assessing levator ani muscles stiffness,and there was no significant difference in the measurements of them,they were suitable for clinical promotion widely.
