“…There was a tendency for malignant masses to be towards the blue spectrum (lower velocities), which is similar to the findings of Magarelli et al and Park et al [16, 17]. The proportion of lesions found to be malignant did not differ substantively between those lesions that where predominantly blue, cyan, or yellow, but those with predominantly red lesions were less likely to be malignant.…”

ObjectivesTo determine if quantitative and qualitative shear wave elastography have roles in evaluating musculoskeletal masses.Methods105 consecutive patients, prospectively referred for biopsy within a specialist sarcoma centre, underwent B-mode, quantitative (m/s) and qualitative (colour map) shear wave elastography. Reference was histology from subsequent biopsy or excision where possible. Statistical modelling was performed to test elastography data and/or B-mode imaging in predicting malignancy.ResultsOf 105 masses, 39 were malignant and 6 had no histology but benign characteristics at 12 months. Radiologist agreement for B-mode and elastography was moderate to excellent Kw 0.52-0.64; PABAKw 0.85-0.90). B-Mode imaging had 78.8% specificity, 76.9% sensitivity for malignancy. Quantitatively, adjusting for age, B-mode and lesion volume there was no statistically significant association between longitudinal velocity and malignancy (OR [95% CI] 0.40[0.10, 1.60], p=0.193), but some evidence that higher transverse velocity was associated with decreased odds of malignancy (0.28[0.06, 1.28], p=0.101). Qualitatively malignant masses tended to be towards the blue spectrum (lower velocities); 39.5% (17/43) of predominantly blue masses were malignant, compared to 14.3% (1/7) of red lesions.ConclusionsQuantitatively and qualitatively there is no statistically significant association between shear wave velocity and malignancy. There is no clear additional role to B-mode imaging currently.Key Points • Correlation between shear wave velocity and soft tissue malignancy was statistically insignificant • B-mode ultrasound is 76.9 % sensitive and 78.8 % specific • Statistical models show elastography does not significantly add to lesion assessment

“…There is only limited published data on the role of sonoelastography in the evaluation of soft tissue masses [16, 17]. The aim of this study was to determine whether quantitative and qualitative shear wave elastography when assessed along with B-mode US imaging could have a role in the evaluation of musculoskeletal soft tissue masses.…”

“…13 Magarelli et al 9 reported that SE can be a useful method for evaluation of superficial soft-tissue lesions and that malignant lesions exhibit increased stiffness on SE. Likewise, our study revealed a different SE pattern between malignant tumour and benign tumour, including epidermoid tumour; malignant tumours showed a harder nature than did benign tumours (p , 0.05), but there was no significant difference in the SE pattern between epidermoid tumour and other benign tumours.…”

“…Strain elastography (SE) has been introduced for the diagnosis of soft-tissue tumours and is used to evaluate tissue stiffness. 9,10 Hard lesions are more resistant to extrinsic compression and show smaller strain, whereas soft lesions show larger strain. 10 Patel et al 11 reported that most epidermoid tumours show a predominant blue colour, which represents their hard nature.…”

“…Malignant lesions have been shown to be stiffer on strain elastography compared with benign lesions on a semi-quantitative scale, similar to lesions outside of the musculoskeletal system[50]. However, a recently published study by the group in Leeds assessing the role of shear wave elastography in musculoskeletal tumours has been unable to replicate these early findings, with the authors concluding that there is currently no additional role for shear wave elastography in soft tissue tumours compared with B mode imaging[51].…”

Ultrasound is an essential modality within musculoskeletal imaging, with the recent addition of elastography. The elastic properties of tissues are different from the acoustic impedance used to create B mode imaging and the flow properties used within Doppler imaging, hence elastography provides a different form of tissue assessment. The current role of ultrasound elastography in the musculoskeletal system will be reviewed, in particular with reference to muscles, tendons, ligaments, joints and soft tissue tumours. The different ultrasound elastography methods currently available will be described, in particular strain elastography and shear wave elastography. Future directions of ultrasound elastography in the musculoskeletal system will also be discussed.
