Although the 3T MR-PET system has been used clinically for the whole body, PET/CT still has advantages over this technique when evaluating the pulmonary region. Ultrashort TE with 3D variable-TE stack-of-spirals sampling has been used for pulmonary nodule detection in MR examination1, which allows for shorter scanning times using an undersampling technique in combination with iterative self-consistent parallel imaging reconstruction (SPIRiT). The goal of this study was to investigate the feasibility of this technique for detecting pulmonary nodules in the 3T MR-PET scanner, which has fewer coil elements compared with most other MR-only scanners, to achieve minimum PET attenuation.
