Inter- and intra-reader reproducibility of shear wave elastography measurements for musculoskeletal soft tissue masses.

ABSTRACT:

Objective

To determine inter- and intra-reader reproducibility of shear wave elastography measurements for musculoskeletal soft tissue masses.

Materials and methods

In all, 64 patients with musculoskeletal soft tissue masses were scanned by two readers prior to biopsy; each taking five measurements of shear wave velocity (m/s) and stiffness (kPa). A single lesion per patient was scanned in transverse and cranio-caudal planes. Depth measurements (cm) and volume (cm³) were recorded for each lesion, for each reader. Linear mixed modelling was performed to assess limits of agreement (LOA), inter- and intra-reader repeatability, including analyses for measured depth and volume.

Results

Of the 64 lesions scanned, 24 (38%) were malignant. Bland-Altman plots demons
