Validation of Intravoxel Incoherent Motion MRI using Perfused Explanted Human Livers. Magn Reson Med. 2025 Nov 14. DOI: 10.1002/mrm.70184. Epub ahead of print. **Contents and Details** Folder: MRData For each donor, 9 IVIM datasets are provided: 4 acquired using a conventional monopolar IVIM acquisition and 5 acquired using a b-M1-optimized IVIM acquisition. For both IVIM acquisitions, datasets were acquired sequentially at total volumetric flow rates of 0, 600, 900, and 1200 mL/min. For the b-M1-optimized acquisition, data was also re-acquired at a flow rate = 0 at the end of the MR exam (i.e., 0end). Data was acquired on a 3T Signa Premier MRI system (GE Healthcare). Data is stored as 5D Matlab arrays (x-dim, y-dim, b-M1-pair, slices, diffusion directions). b-values and M1 values associated with the third dimension are also provided as separate 1D arrays. All datasets contain 27 b-M1-pairs and 3 orthogonal diffusion encoding directions (i.e., 81 total volumes). File: Supporting_Information_Measurements.xlsx Excel file containing donor information for each explanted liver (sex, age, BMI, fibrosis stage, type of death, cause of death, reason not transplanted, and preservation time before imaging) and ultrasonic flowmeter measurements performed during perfusion setup to confirm target total volumetric flow rates of 0.6, 0.9, and 1.2 L/min. It also contains MR estimates of the preservation solution for vials collected immediately before and after each explanted liver MR exam, as well as STEAM-MRS, T1-weighted volumetric, and IVIM estimates obtained at total volumetric flow rates of 0start, 0.6, 0.9, 1.2, and 0end L/min for each explanted liver. File: bM1opt_Acquisition_Waveforms.mat Matlab data file containing the b-M1-optimized diffusion and flow encoding gradient waveforms designed to realize the b-M1-optimized IVIM data acquisition. Waveforms are saved as a 2D array (b-M1-pair, time) with units of T/m and a temporal resolution of dt=0.5 ms (note: echo readout time after gradient waveform not included). b-values and M1 values associated with each waveform are also provided as separate 1D arrays.","journal":"Zenodo (CERN European Organization for Nuclear Research)","year":2025,"id":586073,"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":0.0,"corpus_rank":10062,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.9386,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"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":715713,"name":"Gregory Simchick","orcid":"0000-0001-9326-7203","position":0,"is_corresponding":true}],"reference_count":0,"raw_metadata":null,"created_at":"2026-07-19T02:59:28.666390Z","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":[]}
