abstract = {In this study, a new series of 3D printable
rubber-elastomeric polymer called PORO-LAY materials have
been investigated regarding their suitability to serve as
tissue mimicking materials (TMMs) for MRI phantoms. PORO-LAY
materials have been previously used in biofuel cell
developments, particle filtrations and modeling elastic
tissues. We evaluated the electrical permittivity,
electrical conductivity, spin-lattice T1-relaxation time and
acquired the MRI contrast for simple and multi-material
complex 3D printed shapes made of PORO-LAY materials at 3.0
T. The results showed a T1 diversity within PORO-LAY
materials, which reveals in different MR image contrasts.
The outcome favors PORO-LAY as an appropriate candidate that
can be used in multi-materials additive manufacturing to
produce realistic shapes such as white/grey matter
structures for MRI phantoms with visible clear contrast.
Finally, this study could serve as a reference and guideline
when using these materials as tissue mimicking materials for
different types of human body tissues and provide a
promising opportunity to design novel phantoms for a wide
range of MRI applications.},
