Abstract

Shear wave elastography is a new noninvasive tool for the analysis of the biomechanical properties of the muscles in healthy and pathological conditions. Shear wave elastography is currently considered as a promising real-time visualization tool for quantifying explicitly the mechanical properties of soft tissues in sports medicine including muscle strain injury (MSI). This chapter shows utilizing diagnostic tools of magnetic resonance imaging, B mode ultrasound (US), and shear wave elastography in both acute and chronic phases. Also, the proposal for this chapter is to indicate the possibility of utilizing shear wave elastography for musculoskeletal injury, not only properties of the muscle but also fascial tissues. It introduces the relationship between previous muscle strain injury and local soft tissue stiffness, and we assessed the mechanical properties of soft tissues from a clinical perspective.

Highlights

  • In the sports medicine field, in order to evaluate musculoskeletal conditions such as muscle strain injury (MSI), magnetic resonance imaging (MRI) is commonly used in the diagnosis and prognosis of MSI

  • Even though the B mode US can evaluate the chronic phase of injured tissue, it is less sensitive than MRI to residual morphologic changes after MSI for the higher soft-tissue contrast and high to extracellular fluid in MRI [31]

  • shear wave elastography (SWE) is a promising diagnostic modality for MSI and the accurate measurement of muscle and fascial tissues’ properties, which has a major impact in clinical practice

Summary

Introduction

In the sports medicine field, in order to evaluate musculoskeletal conditions such as muscle strain injury (MSI), magnetic resonance imaging (MRI) is commonly used in the diagnosis and prognosis of MSI. Adipose tissue and fluid components appear white on T2-weighted images and can be used to detect the presence of pathological or morphological changes. It can be Elastography - Applications in Clinical Medicine used to assess fibrotic scar tissue when returning to sports or in the chronic phase of muscle injury to show anatomical features of the tissue [2]. Because of its excellent contrast, high spatial resolution, and ability to view soft tissues with multiplanar evaluation, MRI currently appears to be the best imaging method for early-phase diagnosis and follow-up cases of muscle injuries. While the US can be a well-detected imaging method to assess adjunct tissues and can determine real-time conditions of muscle injuries
