Here we describe application of this method for magnetic relaxation measurements in the living human brain. We report values of the longitudinal relaxation time T1 for brain tissues, measured in vivo for the first time at microtesla fields. The experiments were performed at 46 muT field using a seven-channel SQUID system designed for microtesla MRI and MEG. Values of T1, measured for different tissues at this field, are found to be close (within 5%) to the corresponding values of the transverse relaxation time T2 at the same field. Implications of this result for imaging contrast in microtesla MRI are discussed.","is_dataset_classified":null,"base_score":3.970291913552122,"endowment":3.970291913552122,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26207759","pmcid":null,"openalex_id":"https://openalex.org/W2123926457","authors":[],"funders":[{"funder_name":"National Institutes of Health","grant_id":"5R01EB006456-03","title":"Simultaneous MEG and ULF MRI for Functional Imaging"}],"total_grants":1,"fwci":1.9048,"citation_percentile":0.8526916,"influential_citations":0,"citation_trend":[{"year":2012,"count":4},{"year":2013,"count":11},{"year":2014,"count":4},{"year":2015,"count":2},{"year":2016,"count":1},{"year":2017,"count":2},{"year":2018,"count":4},{"year":2019,"count":7},{"year":2020,"count":4},{"year":2021,"count":2},{"year":2022,"count":2},{"year":2023,"count":5}],"oa_status":"green","license":"IEEE Copyright","oa_locations":[{"url":"https://arxiv.org/pdf/0811.0389","host_type":"repository"},{"url":"https://arxiv.org/pdf/0811.0389","host_type":"repository"},{"url":"http://xplorestaging.ieee.org/ielx5/77/5166641/05067146.pdf?arnumber=5067146","host_type":"publisher"},{"url":"http://arxiv.org/abs/0811.0389","host_type":"repository"},{"url":"https://doi.org/10.1109/tasc.2009.2018764","host_type":"journal"},{"url":"http://arxiv.org/pdf/0811.0389","host_type":""},{"url":"https://dx.doi.org/10.48550/arxiv.0811.0389","host_type":""},{"url":"https://dx.doi.org/10.1109/tasc.2009.2018764","host_type":""}],"fields_of_study":["Advanced MRI Techniques and Applications","Advanced Neuroimaging Techniques and Applications","NMR spectroscopy and applications","03 medical and health sciences","0302 clinical medicine"],"mesh_terms":[],"keywords":["Relaxometry","Nuclear magnetic resonance","Squid","Magnetic resonance imaging","Human brain","Materials science","In vivo","Astrocytosis","Biomedical engineering","Medicine","Neuroscience","Radiology","Pathology","Spin echo","Biology","Physics","Physics - Instrumentation and Detectors","FOS: Physical sciences","Medical Physics (physics.med-ph)","Instrumentation and Detectors (physics.ins-det)","Physics - Medical Physics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T16:14:34.716651Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
