Change DICOM Header without reading and writing the whole file

Hello guys!

I'm having problems renaming my DICOM headers. I am able to read the headers (dicominfo()) and then change them to whatever I want. Then I want to save the DICOM file with the new header. At the moment im reading the file (dicomread()) and then save it with dicomwrite(). This works fine but unfortunatly it takes a lot of time to change the headers of a complete CT scan. Is there a faster way?

Since I am only changing the headers, not the file itself I would like to avoid reading the file ...

Thank you!

edit: I already tried movefile, which is fast. But this function doesn't include the header information

I'm not sure if this is suitable for your purpose but I have found https://www.mathworks.com/matlabcentral/fileexchange/29145-dicom-tags-read-and-write very useful for editing DICOM tags and writing to file.
