Magnetic resonance elastography (MRE) and ultrasound elastography (USE) are imaging techniques that non-invasively quantify the mechanical properties of tissue using magnetic resonance (MR) and ultrasound imaging systems. Using present-day elastographic techniques, it is difficult to quantitatively detect small viscoelastic changes deep inside the body. If this problem can be solved, elastography may be used effectively for the early detection of pancreatic cancer and other tumors, discrimination between malignant and benign tumors, and determination of the extent of invasion. In this study, we aim to develop a system that can quantitatively obtain details such as the viscoelasticity of small organs and tissues in the body, using clinical MR imaging and MR microscopy. By evaluating MRE and USE using a soft tissue-equivalent gel phantom whose viscoelastic coefficient is known, we aim to investigate the characteristics of both the devices and promote their standardization.
