{"doi":"10.1002/nbm.70006","title":"B<sub>0</sub> Magnetic Field Conditions in the Human Heart at 3 T Across One Thousand Subjects: A Numerical Simulation Study","abstract":"ABSTRACT Functional scans in cardiovascular magnetic resonance (CMR) adopting bSSFP sequences suffer from dark band artifacts due to B 0 inhomogeneity. The best remedy to mitigate this issue is through cardiac B 0 shimming. The development of an optimal B 0 shim strategy for the human heart is hindered by a limited understanding of B 0 conditions in clinical diagnostic orientations of CMR. Here, we present high‐resolution B 0 distributions in cardiac imaging planes, derived from simulations utilizing high‐resolution computed tomography (CT) images from 1008 subjects, and present an oblique slicing method to derive such B 0 distributions. This study also presents a theoretical analysis of spherical harmonic B 0 shimming at 3 T using a static global approach and slice‐specific dynamic shim updating in the short‐axis view of human hearts. The characteristics of cardiac B 0 conditions along with spherical harmonic shimming were correlated with the subjects' demographic parameters, with weak or no correlations, suggesting limited demographic commonality and predominantly subject‐specific characteristics in cardiac B 0 . The segmented lung volume shows more significant associations and relatively higher correlations with B 0 conditions, indicating that B 0 conditions in the heart rely on the anatomy surrounding the heart more than overall body shape and size. This research provides a basis for the development of optimized cardiac B 0 shim strategies.","journal":"NMR in Biomedicine","year":2025,"id":543082,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9538,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":385457,"name":"Sebastian Theilenberg","orcid":"0000-0003-3439-5111","position":1,"is_corresponding":false},{"id":1432480,"name":"Boyu Peng","orcid":"0000-0002-2487-877X","position":2,"is_corresponding":false},{"id":1432481,"name":"Wolfgang Schreiber","orcid":"0000-0002-8827-1838","position":3,"is_corresponding":false},{"id":279049,"name":"Andrew J.
