Phantoms doped with paramagnetic materials are commonly used for quality assessment of MRI protocols and image reconstruction techniques. These phantoms are typically prepared using cylindrical containers and mimic the T1 /T2 characteristics of human tissue. In this work, we propose a 1:1 scale human head and neck agar-agar phantom prepared using a 3D human model. The phantom mimics human tissue characteristics while incorporating the skull and cervical vertebrae. The MRI images show that the phantom closely matches human anatomy, and the susceptibility artifacts in EPI images successfully mimic those seen during in vivo imaging of the brain and spine.
