Matching contrasts

Hi there.
I want to use the brain dataset. How can I match different contrasts? I want to match different contrast images from the same cross-section of the same subjects? The file names are different.

Hello @Ridvan_Yesiloglu, I don’t think this is possible. In order to fit the examinations into a clinical window, only one sequence for each patient was fully-sampled.

But how are the dicom files generated? There are multiple contrasts per subjects.

Ah yes. The DICOM files are completely separate. Those are all normal cases acquired with subsampling. So you can match contrasts there - would be interesting if you were to develop a model there that might transfer to the raw data.
