This study aimed to compare the visibility of a formalin-fixed heart using various 3D MRI sequences as well as to determine the optimal sequence for computational modeling of congenital heart diseases. Our results demonstrated that MPRAGE showed the best contrast with good image quality for imaging of the myocardium and the vascular structure when surrounded by normal saline in a plastic container. We believe that computational cardiac modeling of human autopsied heart specimens using MPRAGE plays a critical role in education and/or research.
