abstract = {BackgroundMagnetic resonance is a major preclinical and
clinical imaging modality ideally suited for longitudinal
studies, e.g. in pharmacological developments. The lack of a
proven platform that maintains an identical imaging protocol
between preclinical and clinical platforms is solved with
the construction of an animal scanner based on clinical
hard- and software.MethodsA small animal magnet and gradient
system were connected to a clinical MR system. Several
hardware components were either modified or built in-house
to achieve compatibility. The clinical software was modified
to account for the different field-of-view of a preclinical
MR system. The established scanner was evaluated using
clinical QA protocols, and platform compatibility for
translational research was verified against clinical
scanners of different field strength.ResultsThe constructed
animal scanner operates with the majority of clinical
imaging sequences. Translational research is greatly
facilitated as protocols can be shared between preclinical
and clinical platforms. Hence, when maintaining sequences
parameters, maximum similarity between pulses played out on
a human or an animal system is maintained.ConclusionCoupling
of a small animal magnet with a clinical MR system is a
flexible, easy to use way to establish and advance
translational imaging capability. It provides cost and labor
efficient translational capability as no tedious sequence
reprogramming between moieties is required and
cross-platform compatibility of sequences facilitates
multi-center studies.},
