isdicom

The ISDICOM function takes a filename or a cell array of filenames and returns true for DICOM files.

ISDICOM detects if the four byte string starting at position 128 of the file is equal to 'DICM', which indicates that the file is a DICOM file.

This is not a very robust method, since other file types might also accidentally contain the string DICM at position 128, and non-standard DICOM files might not contain this string.
