I’ll have a look when review.source.kitware.com comes back up. It would be OK to replaces the [] operator with using the iterator directly. The only reason I can think of not to is that even with a DICOM file, the time spent in writing and reading the MetaDataDictionary is not going to have a significant computational cost, since it only happens when you read or write a DICOM file. It’s not something done in the inner loop of a big computation.
