Motion correction in simultaneous PET/MR brain imaging using sparsely sampled MR navigators: a clinically feasible tool
BACKGROUND We present a study performing motion correction (MC) of PET using MR navigators sampled between other protocolled MR sequences during simultaneous PET/MR brain scanning with the purpose of evaluating its clinical feasibility and the potential improvement of image quality. FINDINGS Twenty-nine human subjects had a 30-min [(11)C]-PiB PET scan with simultaneous MR including 3D navigat...

متن کاملSparsely sampled MR navigators as a practical tool for quality control and correction of head motion in simultaneous PET/MR
Dept. of Clinical Physiology, Nuclear Medicine and PET, Rigshospitalet (Copenhagen University Hospital), Denmark We present a study using MR navigators sampled between other protocolled MR sequences during PET/MR brain scanning, to make motion-QC and motion correction (MC) feasible in clinical simultaneous PET/MR, obviating the need for special MR sequences with interleaved (dense) navigators. ...
متن کاملGRAPPA navigators: motion correction with parallel imaging
Introduction: Typically, spatial encoding in MRI is performed entirely with gradient fields, while the use of multiple RF coils is primarily to extend anatomical coverage and boost SNR. However, signals acquired by different coils, with localized sensitivities, inherently contain spatial information. Partially parallel imaging (PPI) in MRI makes use of this built-in redundant spatial informatio...
متن کاملRespiratory motion correction in oncologic PET using T1-weighted MR imaging on a simultaneous whole-body PET/MR system.
UNLABELLED Hybrid PET/MR combines the exceptional molecular sensitivity of PET with the high resolution and versatility of MR imaging. Simultaneous data acquisition additionally promises the use of MR to enhance the quality of PET images, for example, by respiratory motion correction. This advantage is especially relevant in thoracic and abdominal areas to improve the visibility of small lesion...
