Correlation of PET and MRI for comparing assessments on myocardial viability

Spatially correlating images from different imaging modalities could provide complementary information of physiopathology of the heart. In this study, a surface-based registration technique, relied on integrating morphological information extracted from image datasets, was employed to co-register the functional and anatomical information from positron emission tomography (PET) and magnetic resonance imaging (MRI), respectively. We also evaluated the system performance based on external fiducial marker and concluded that the overall registration accuracy is close to intrinsic system limitation. Therefore, comprehensive image information could be performed for comparing assessments on myocardial viability.
