N2 - The use of elastography has become a key method for distinguishing between benign and fibroadenomas breast lesions. This study aimed to investigate the potential of using polyvinyl chloride (PVC) as a breast elastography phantom by comparing its mechanical properties to those of real breast tissues, including fatty tissue, fibroadenoma, and malignant lesions. Based on existing literature, comparative elasticity values for each tissue type were determined, providing benchmarks for validation. The acoustic properties, Young’s modulus, and shear wave elasticity of PVC were measured for comparison. Results Based on the results, PVC displays mechanical properties that are closely aligned with those of breast tissue, particularly when it comes to shear wave elasticity. Conclusion These findings validate the use of PVC as a reliable and cost-effective material for mimicking breast tissue in elastography studies. This study confirms the suitability of PVC as a phantom material, opening up new avenues for improving clinical imaging, training models, and quality assurance.
