Aims and objectives: Phantom models are useful for simulate anthropomorphic structures for the development of new interventional systems, for the implementation and development of innovative medical procedures, for the training of MRI operators and has the advantage of long-term structural stability allowing to perform [...]

Methods and materials: To develop the present anthropomorphic phantom we followed the process depicted in Fig.1 In vivo tissue signal measurements Determination of T1 and T2 relaxation times: we had local institutional review board approved for all MRI examinations and written informed consent was obtained from each vol[...]

Conclusion: The spine phantom was successfully assembled using respective components in anthropomorphic geometry. Nerve tissue was simulated with agarose-impregnated polyethylene fibres. Using the finished phantom, a fat-supressed T2-weighted 3D STIR SPACE was acquired for the MR neurography imaging. Subsequent[...]
