Clinical Scorecard: Evaluating the Diagnostic Accuracy and Clinical Relevance of Shear-Wave Elastography for Musculoskeletal Soft-Tissue Tumors: A Systematic Review

At a Glance

Key Highlights

• SWE shows high reproducibility (intraclass correlation coefficient > 0.85 in four studies).
• Diagnostic performance of SWE varies widely (AUC range 0.57-0.87).
• SWE may have higher specificity for benign-appearing or superficial lesions compared to ultrasonography.
• MRI remains superior in most direct comparisons for diagnostic accuracy.
• Standardized acquisition protocols and vendor calibration are necessary for broader clinical adoption.

Guideline-Based Recommendations

Diagnosis

• SWE should be used selectively for superficial, non-fatty lesions as an adjunct to ultrasonography.

Management

• SWE is not recommended as a stand-alone diagnostic tool.

Monitoring & Follow-up

• Further studies are needed to establish standardized protocols for SWE application.

Risks

• Misclassification of lesions can lead to delayed oncologic care or unnecessary procedures.

Patient & Prescribing Data

Patients with soft-tissue tumors requiring differentiation between benign and malignant lesions.

SWE may improve diagnostic classification when combined with conventional ultrasound.

Clinical Best Practices

• Utilize SWE in conjunction with other imaging modalities for comprehensive assessment.
• Consider lesion characteristics and depth when interpreting SWE results.
