Comparison of Real-time and Shear Wave Elastography — Elasto  

Breast Diseases Clinical Trial

Official title: Comparison of Accuracy and Reproducibility of Breast Lesion Characterization Between Real Time Elastography and Shear Wave Elastography

Status Active, not recruiting

Clinical Trial Summary

Tissue elasticity is being increasingly used as diagnostic parameter, since at the macroscopic level benign breast lesions tend to be stiffer than normal breast tissue but softer than breast cancers. Ultrasound elastography allows to probe the elasticity of breast lesions in clinics. Real time elastography (RTE) and shear wave elastography (SWE) are the two most widely used elastography modalities. Assessment of breast lesions by either RTE or SWE improve the diagnostic performance of standard B-mode ultrasound (US) and have the potential to assist the decision about whether to perform a breast biopsy or not.

Clinical Trial Description

Tissue elasticity is being increasingly used as diagnostic parameter, since at the macroscopic level benign breast lesions tend to be stiffer than normal breast tissue but softer than breast cancers. Ultrasound elastography allows to probe the elasticity of breast lesions in clinics. Real time elastography (RTE) and shear wave elastography (SWE) are the two most widely used elastography modalities. Assessment of breast lesions by either RTE or SWE improve the diagnostic performance of standard B-mode ultrasound (US) and have the potential to assist the decision about whether to perform a breast biopsy or not. However, employing RTE and SWE using the same equipment to directly compare elasticity measurements of a breast lesion has not been done. Investigators propose to prospectively investigate inter-observer agreement of each modality. The study will investigate and compare the accuracy and reproducibility of SWE and RTE in the characterization of breast lesions. Furthermore, we plan to establish learning curves for RTE and SWE. In this project, investigators will compare RTE and SWE concerning their potential to discriminate benign breast lesions from breast cancer. Investigators aim is to identify which modality will allow clinicians the best possible patient care. ;
