Extended MRI-based PET motion correction for cardiac PET/MRI.

ABSTRACT:

Purpose

A 2D image navigator (iNAV) based 3D whole-heart sequence has been used to perform MRI and PET non-rigid respiratory motion correction for hybrid PET/MRI. However, only the PET data acquired during the acquisition of the 3D whole-heart MRI is corrected for respiratory motion. This study introduces and evaluates an MRI-based respiratory motion correction method of the complete PET data.

Methods

Twelve oncology patients scheduled for an additional cardiac ¹⁸F-Fluorodeoxyglucose (¹⁸F-FDG) PET/MRI and 15 patients with coronary artery disease (CAD) scheduled for cardiac ¹⁸F-Choline (¹⁸F-FCH) PET/MRI were included. A 2D iNAV recorded the respiratory motion of the myocardium during the 3D whole-heart coronary MR angiography (CMRA)
