This repository contains in vitro and in vivo MRI data acquired on a 3T clinical system (MAGNETOM Prismafit, Siemens Healthcare, Erlangen, Germany) using a commercially available 18-channel body coil. All data includes both magnitude and phase information in DICOM format. Data was collected and used in a study untitled "SPARCQ: A new approach for fat fraction mapping using asymmetries in the phase-cycled bSSFP signal profile" by Rossi et. al. (2023). The detailed contents of the repository are listed below: /PHANTOM: 3D acquisitions of a custom fat-water phantom with 6 vials of different peanut oil and water concentrations /PCbSSFP NPC=37 Phase-Cycled bSSFP acquisitions with phase increments [0°:10°:360°] /MEGRE MultiEcho GRE acquisition with 13 monopolar echoes TE1/\(\Delta\)TE=1.34/1.98 ms /V1 to /V6: 3D knee acquisitions from n=6 healthy volunteers /Scan NPC=37 Phase-Cycled bSSFP acquisitions with phase increments [0°:10°:360°] /Rescan NPC=37 Phase-Cycled bSSFP acquisitions with phase increments [0°:10°:360°] after volunteer repositioning (repeatability experiment) /Dixon In-phase, out-of-phase, fat-only and water-only images reconstructed from a Turbo Spin Echo Dixon sequence /V7 and /V8: 3D knee acquisitions from n=2 healthy volunteers /Scan NPC=37 Phase-Cycled bSSFP acquisitions with phase increments [0°:10°:360°] /MEGRE MultiEcho GRE acquisition with 13 monopolar echoes TE1/\(\Delta\)TE=1.34/1.98 ms ************************************************************************************************************************************************************************************************************************************************************ Link to publication: https://onlinelibrary.wiley.com/doi/full/10.1002/mrm.29813 ************************************************************************************************************************************************************************************************************************************************************ Data was collected and approved for sharing according to institutional rules (Ethics Commitee, CHUV, Lausanne, Switzerland).
