Three‐Dimensional Shear Wave Elastography of Skeletal Muscle: Preliminary Study

Abstract

Both 2D SWE and 3D SWE are suitable techniques for clinical use, depending on the examiner's experience/preference. However, 3D SWE provides a multiplanar/multislice view that better illustrates the spatial characteristics of muscle tissue. Three-dimensional SWE may be a new method for fully visualizing the musculoskeletal system.

Poroelasticity as a Model of Soft Tissue Structure: Hydraulic Permeability Reconstruction for Magnetic Resonance Elastography in Silico

“…The shear modulus did not show this behavior, with image reconstruction recovering inclusion geometry and relative distribution very well by the 50 th iteration, although different initial conditions are seen to lead to different final absolute values -a peculiarity noted in prior work [106]. The lower panels of Figures 5,6,8,9 show the inference trajectories, with initial estimates noted by an asterisk and changes in descent strategy indicated by red markers.…”

“…Plugging the first of these in Eq. (8) shows that in this regime α → 1, while using all three in Eq. (12) shows that M −1 → 0.…”

“…[6] for k. For the 1Hz data, the shear modulus results are shown in Fig. [8] and the hydraulic permeability in Fig. [9].…”

“…Connecting macroscopic mechanical response to microscopic cellular organization of tissue, MRE opens up new avenues for assessing the etiology of tissue pathology. The modality has been implemented to varying degrees of success on skeletal muscle [1][2][3][4][5][6][7][8][9], breast [10][11][12][13][14][15][16][17], liver [18][19][20][21][22][23][24], and brain [25,26].…”

Emerging technologies in neuromuscular ultrasound

“…More work in muscle disorders is needed before any conclusions can be reached. Newer approaches, including 3D SWEI, may aid in improving additional research …”
