In an effort to expand the existing MRI reference material available to Medical professionals, including developmental anatomists, foetal specimens of gestational ages ranging from 7-26 weeks were scanned using ultra high field MRI systems ( 7 Tesla) and high resolution, multiplanar images of the whole body were obtained in each of these specimens. A unique set of processes, materials and equipment facilitated the execution of these MRI scans including custom built specimen holders, transmit and receive coils, protocol optimization and image reconstruction techniques. Using these techniques, a total of 21 preserved ex-vivo fetal specimens were successfully scanned.
