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.}, cin = {ZEA-1 / INM-2}, ddc = {620}, cid = {I:(DE-Juel1)ZEA-1-20090406 / I:(DE-Juel1)INM-2-20090406}, pnm = {573 - Neuroimaging (POF3-573)}, pid = {G:(DE-HGF)POF3-573}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000591065100001}, doi = {10.1088/2053-1591/abc76f}, url = {https://juser.fz-juelich.de/record/887685}, }
