Description
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
