DCE MRI technique is widely used in tissue characterization and tissue perfusion. Current work focuses on the design and development of a low cost in vivo DCE phantom for providing a reference standard for quantitative validation and the ability to generate Signal Intensity curves similar to arterial input functions. Poly vinyl Alcohol material was used in the phantom to mimic tissue perfusion characteristics and obtain signal intensity curves for different flow rates. We obtained similar curves compared to Arterial Input Function and were able to control flow rates through different tube and pore sizes.
