Dear Dr. @fedorov , and Dr. @pieper , Is there any way to import 4D perfusion NIFTI image to DSCMRIAnalysis? I understand that currently, only DICOM images can be imported as input to DSCMRIAnalysis module. However, I want to make some preprocessing (e.g. motion correction, registration) of DICOM i…

Dear Dr. @fedorov , Thanks to your help, I’ve already tried @pieper ’s python code, and it was successful in saving NIFTI files in NRRD files. However, when I enter these NRRD files as inputs to DSCMRIAnalysis module, then it does not recognize frame identifying DICOM tag (error msg below). [image…

In the NRRD file you sent me, the attributes that are needed for the analysis are not initialized. You should specify the following (this is how they are initialized if the DICOM series is imported directly from DICOM for the dataset you shared): MultiVolume.FrameIdentifyingDICOMTagName:=Time Mult…

Dear Dr. @fedorov , Thank you so much for your kind information. I managed to add some lines for the code, and the following result is acquired. import os import slicer import MultiVolumeImporter path1 = “/home/cndl/DSC/test/4d_nifti/” path2 = “/home/cndl/DSC/test/nrrd/” #os.mkdir(path2) lis…

You should also initialize frame labels: https://github.com/fedorov/MultiVolumeImporter/blob/master/MultiVolumeImporter.py#L223-L229 https://github.com/fedorov/MultiVolumeImporter/blob/master/MultiVolumeImporter.py#L274-L277 All of this metainformation is not populated when importing 4d NIFTI. If…
