Myocardial T2 mapping using wideband T2 preparation gradient echo readout for patients with implantable cardiac devices at 1.5T [PDF]

Journal of Cardiovascular Magnetic Resonance
Background: Myocardial T2 mapping enables non-invasive assessment of inflammation and edema. However, in patients with implantable cardiac devices, such as pacemakers or defibrillators (ICDs), off-resonance effects often cause severe image artifacts and ...
