Performance of Diffusion-weighted Imaging-based Virtual MR Elastography (vMRE) for Diagnosing Breast Cancer

19. maj 2026 opdateret af: Yunnan Cancer Hospital

Performance of Diffusion-weighted Imaging-based Virtual MR Elastography (vMRE) for Diagnosing Breast Cancer: A Prospective Study

This study aims to prospectively collect breast MRE and vMRE image data, clinical data, and pathological data from female patients due to breast lesions indicated by mammography or ultrasound with BI-RADS category 4 or above. It evaluates the consistency of MRE and vMRE in measuring breast lesions and compares the diagnostic performance of the two methods in distinguishing between benign and malignant breast conditions, with the goal of determining whether vMRE has the potential to replace or supplement MRE. Furthermore, it explores and compares the correlation and diagnostic efficacy of sADC and virtual shear modulus calculated at different b-values with the true shear modulus, aiming to identify and optimize the optimal imaging protocol suitable for breast imaging. It also investigates the correlation between quantitative parameters of vMRE and MRE and pathological results such as patient pathological grading and molecular typing, providing imaging evidence for individualized precision assessment.
