{"doi":"10.1002/nbm.4608","title":"A radially interleaved sodium and proton coil array for brain MRI at 7 T","abstract":"The objective of the current study was to design and build a dual‐tuned coil array for simultaneous 23 Na/ 1 H MRI of the human brain at 7 T. Quality factor, experimental B 1 + measurements, and electromagnetic simulations in prototypes showed that setups consisting of geometrically interleaved 1 H and 23 Na loops performed better than or similar to 1 H or 23 Na loops in isolation. Based on these preliminary findings, we built a transmit/receive eight‐channel 23 Na loop array that was geometrically interleaved with a transmit/receive eight‐channel 1 H loop array. We assessed the performance of the manufactured array with mononuclear signal‐to‐noise ratio (SNR) and B 1 + measurements, along with multinuclear magnetic resonance fingerprinting maps and images. The 23 Na array within the developed dual‐tuned device provided more than 50% gain in peripheral SNR and similar B 1 + uniformity and coverage as a reference birdcage coil of similar size. The 1 H array provided good B 1 + uniformity in the brain, excluding the cerebellum and brain stem. The integrated 23 Na and 1 H arrays were used to demonstrate truly simultaneous quantitative 1 H mapping and 23 Na imaging.","journal":"NMR in Biomedicine","year":2021,"id":178724,"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":19,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9573,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":528775,"name":"Bei Zhang","orcid":"0000-0002-9718-1594","position":1,"is_corresponding":false},{"id":724698,"name":"Zidan Yu","orcid":"0000-0003-3405-7227","position":2,"is_corresponding":false},{"id":697811,"name":"Carlotta Ianniello","orcid":"0000-0003-1749-6842","position":3,"is_corresponding":false},{"id":489168,"name":"Karthik Lakshmanan","orcid":"0000-0003-0187-495X","position":4,"is_corresponding":false},{"id":474096,"name":"Jan Paška","orcid":null,"position":5,"is_corresponding":false},{"id":697814,"name":"Guillaume Madelin","orcid":"0000-0002-5556-5792","position":6,"is_corresponding":false},{"id":475584,"name":"Martijn A.
