N2 - Magnetic resonance (MR) and positron emission tomography (PET) are promising non-invasive techniques for imaging the cardiovascular system. In the current clinical practice, MR is considered the gold standard for the assessment of cardiac anatomy, ventricular function, and myocardial viability from late gadolinium enhancement (LGE) images, while PET remains the reference modality for quantitative assessment of myocardial perfusion. The versatility of MR has enabled the development of quantitative techniques, which have shown encouraging results for early detection of cardiac disease through accurate tissue characterization. In addition, advances in motion compensation and acceleration of data acquisition have paved the way toward free-breathing whole-heart MR imaging for various clinical applications. Furthermore, the introduction of hybrid PET-MR scanners and the development of targeted PET radiotracers has opened new exciting possibilities for the assessment of coronary atherosclerosis and inflammatory cardiac diseases, promising a more comprehensive assessment from the complementary information that can be obtained from both imaging modalities. This chapter reviews some of the recent innovations in cardiac MR and PET-MR imaging, focusing on the trends towards quantitative and efficient whole-heart MR imaging and novel technical developments in cardiac PET-MR.
