Abstract

Abstract:

Objective

To discuss the application of shear wave elastography and strain elasticity imaging diagnosis of infants with congenital muscular torticollis.

Methods

Children with congenital muscular torticollis in 50 patients and 100 healthy infants were recruited for the research at Shezhen Children′s Hospital in the period of September to December, analyzing factors in normal sternocleidomastoid two mode ultrasonic elastography, including the young′s modulus, shear wave velocity, shear modulus and the ratio of strain results, comparing the change of elasticity between the patients and normal.

Results

The elastic parameters of the sternocleidomastoid showed no statistically significant difference between the genders, the left side and the right side. The results of young′s modulus, shear wave velocity and shear wave modulus were higher in long axis section than the short axis section, and the difference was statistically significant (P<0.05). However, the results of the strain ratio and thickness was not statistically significant. The young′s modulus, shear wave velocity and shear wave modulus are higher in the stretch back position than symmetrical supine position, and the difference is statistically significant (P<0.05). But those of strain ratio and thickness was not statistically significant. The thickness of the sternocleidomastoid muscle and the young′s modulus, shear wave velocity, shear modulus and the ratio of strain results ultrasound elastic results were higher in the lesion side than the healthy side, and the difference is statistically significant (P<0.05).

Conclusion

The ultrasound elastic imaging of multimodal technique can quantify the elasticity of the normal infant and the patients sternocleidomastoid, be used for diagnose for the infants with the congenital muscular torticollis.
