abstract = {This study aims to integrate an ultra-high-strength
gradient coil system on a clinical 3 T magnet and
demonstrate its preclinical imaging capabilities. Dedicated
phantoms were used to qualitatively and quantitatively
assess the performance of the gradient system. Advanced MR
imaging sequences, including diffusion tensor imaging (DTI)
and quantitative susceptibility mapping (QSM), were
implemented and executed on an ex vivo specimen as well as
in vivo rats. The DTI and QSM results on the phantom agreed
well with those in the literature. Furthermore, studies on
ex vivo specimens have demonstrated the applicability of DTI
and QSM on our system to probe microstructural changes in a
mild traumatic brain injury rat model. The feasibility of in
vivo rat DTI was also demonstrated. We showed that the
inserted ultra-high-strength gradient coil was successfully
integrated on a clinically used magnet. After careful tuning
and calibration, we verified the accuracy and quantitative
preclinical imaging capability of the integrated system in
phantom and in vivo rat brain experiments. This study can be
essential to establish dedicated animal MRI platform on
clinical MRI scanners and facilitate translational studies
at clinical settings.},
