Ultrasound shear-wave elasticity and magnetic resonance diffusion coefficient show strong inverse correlation in small fibroadenomas

Objective: Stiffness of breast lesions helps distinguish malignant from benign solid masses. can be quantitatively measured by magnetic resonance and ultrasound imaging using apparent diffusion coefficient (ADC) shear-wave elastography (SWE) techniques, respectively. This study aims to analyze correlations between SWE ADC in biopsy-proven small fibroadenomas. Patients Methods: Shear-wave measurements 50 fibroadenomas were evaluated retrospectively. Mean patient age was 41±13 years (range 27-63). All had maximum diameters ≤20 millimeters. Correlations intralesional ADC, lesion-parenchyma ratio, SWE, heterogeneity index lesion volume analyzed. Results: values as follows: ADC=1.71±0.22 x10-3mm2/s, ratio=1.04±0.09, SWE=73.4±28.8 kPa, minimum SWE=43.9±21.8 kPa =29.4±12.7 kPa. There a strong inverse correlation fibroadenoma (rho = – 0.746, p <0.01). Significant also found 0.525, <0.05) 0.840, Conclusion: Apparent show If proven threshold for characterization are revealed, ultrasonographic diffusion-weighted MRI have potential used interchangeably.
