Cardiac motion and spillover correction for quantitative PET imaging using dynamic MRI

Abstract: Purpose Cardiac positron emission tomography/magnetic resonance imaging (PET/MRI) acquisition presents novel clinical applications thanks to the combination of viability and metabolic imaging (PET) and functional and structural imaging (MRI). However, the resolution of PET, as well as cardiac and respiratory motion in nongated cardiac imaging acquisition protocols, leads to a reduction in image quality and severe quantitative bias. Respiratory or cardiac motion is customarily addressed with gated reconstructio… Show more

“…Motion correction in cardiovascular imaging has been proven to be beneficial. In PET-MRI cardiac studies correcting for cardiac contraction only was able to provide an increase of up to 50% in the SNR compared to the non-corrected images [ 80 ]. Robson et al used RTA to resolve motion in PET-MRI data of patients with cardiac sarcoidosis.…”
