Hello,
The NIfTI file format is a popular format for storing neuroimaging data, such as MRI, fMRI, and PET scans, in a way that is easy to share and analyze using various neuroimaging software tools.
DICOM stands for “Digital Imaging and Communications in Medicine”. It is a standard for handling, storing, and transmitting medical images, as well as associated metadata, such as patient information and imaging parameters.
Yes, it is possible for differences to occur when converting DICOM images from different MRI vendors into NIfTI format using “niftiwrite”. This is because different vendors often have different DICOM implementation standards and image formats.
To ensure accuracy and consistency in the conversion process, you can try the following steps:
1.Check the DICOM tags: Before converting your DICOM images to NIfTI format, confirm that the DICOM tags (especially the image orientation and pixel spacing) are correct and consistent across all images.
2.Use a DICOM to NIfTI conversion software: Another approach is to use a DICOM to NIfTI conversion software that is designed to handle different DICOM implementations and image formats
3.Adjust the image orientation: In some cases, you may need to adjust the image orientation manually before converting to NIfTI format using niftiwrite. You can use the flip, fliplr, or flipud functions to flip images along different axes.

Hope this helps!
