I am trying to write custom DICOM tags to some images I have generated in matlab. I added the tags to the dicom dictionary, "set" the dicom dictionary, then wrote the dicom image using dicomwrite with 'WritePrivate' set to true. Unfortunately, the dicom file that is written does not have the field set. What am I missing?

Although a custom dictionary is being utilized, it is not being passed into the "dicomwrite" function. Consequently, the function defaults to using the "dicom-dict.mat" file, which is the cause of this issue. To resolve this, you can specify the custom dictionary when calling "dicomwrite" by including the "Dictionary" name-value pair argument in the function call:
dicomwrite(img, out_file, write_meta_struct, CreateMode="Copy", WritePrivate=true, Dictionary=custom_dict);

Note that using Name=value syntax was not valid in 2012 when this question was first asked.
