How can I determine the number of frames in very large DICOM files?

In my research, I am dealing with large DICOM files (>10GB) with thousands of frames. These files are too big to load or read as a whole in Matlab, so I want to read them in parts of 1000 frames. On beforehand, I would like to know the total number of frames in the file, but I cannot use dicominfo because of the file size (memory issues). Is there a workaround in Matlab?

Thanks in advance!
