Data from: T1-weighted in vivo human whole brain MRI dataset with an ultrahigh isotropic resolution of 250 μm

We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T1-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucasian subject and was recorded using prospective motion correction. The raw data amounts to approximately 1.2 TB and was acquired in eight hours total scan time. The resolution of this dataset is far beyond any previously published in vivo structural whole brain dataset. Its potential use is to build an in vivo MR brain atlas. Methods for image reconstruction and image restoration can be improved as the raw data is made available. Pre-processing and segmentation procedures can possibly be enhanced for high magnetic field strength and ultrahigh resolution data. Furthermore, potential resolution induced changes in quantitative data analysis can be assessed, e.g., cortical thickness or volumetric measures, as high quality images with an isotropic resolution of 1 and 0.5 mm of the same subject are included in the repository as well.Averaged T1-weighted MPRAGE with an isotropic resolution of 250 µmThis folder contains structural data of a single young healthy Caucasian subject in NIfTI file format. This dataset has been build by registering eight single T1-weighted MPRAGE volumes with a native isotropic resolution of 250 µm and the average to increase the SNR.MPRAGE_250um.tarAll averages of T1-weighted MPRAGE with an isotropic resolution of 250 µmThis folder contains all prior averages of the registration process to build the final T1-weighted MPRAGE volume with an isotropic resolution of 250 µm.averages.tarPre-Processed T1-weighted MPRAGE volumesThis folder contains all eight single pre-processed T1-weighted MPRAGE volumes used to generate the average with an isotropic resolution of 250 µm. Additionally, 1 and 0.5 mm pre-processed data of the same subject are included in the folder. Pre-processing consists of AC-PC alignment and bias field correction. Details can be found in the readme.derivatives.tarSourcedata of T1-weighted MPRAGE volumesThis folder contains all eight single unprocessed T1-weighted MPRAGE volumes used to generate the average with an isotropic resolution of 250 µm. Additionally, 1 and 0.5 mm unprocessed data of the same subject and motion tracking information of all acquisitions is included in the archive.sourcedata.ta
