This dataset provides various acquisitions for T2 mapping of the MnCl2 array of the NIST phantom at 1.5T. Data were acquired on a MAGNETOM Sola (Siemens Healthcare, Erlangen, Germany), with an 18-channel body coil and a 32-channel spine coil (12 elements used). It gathers original acquisitions from Lajous H. et al. (2020) T2 Mapping from Super-Resolution-Reconstructed Clinical Fast Spin Echo Magnetic Resonance Acquisitions. In: Martel A.L. et al. (eds) Medical Image Computing and Computer Assisted Intervention – MICCAI 2020. MICCAI 2020. Lecture Notes in Computer Science, vol 12262. Springer, Cham. https://doi.org/10.1007/978-3-030-59713-9_12.

The dataset is composed of DICOM images from:

i) Gold-standard single-echo spin echo (SE) sequences acquired at variable TE;

ii) Alternative reference multi-echo spin echo (MESE) acquisitions;

iii) Half-Fourier Acquisition Single-shot Turbo spin Echo (HASTE) images at variable TE in three orthogonal orientations.

The acquisition parameters are further detailed in the ReadMe.txt file provided along with the images.

These acquisitions were repeated independently on three different days during the month of January 2020.

These data are made publicly available as a support for further reproducibility studies as well as for the validation of new T2 relaxometry strategies.
