[Insight-users] DICOM Header Info

[TienGarry]

Thank you for your answer, this is the
DictionaryType::ConstIterator end = dictionary.End();
I am curious why I can get the patient weight correctly, but the following code can not
get Radiopharmaceutical Start Time.
entryId = "0018|1072";
tagItr = dictionary.Find( entryId );
You mentioned that 0018,1072 is part of the sequence, and not part of the root element. 
How can I get the value of this key entry, I need the information to calculate the SUV 
value of PET.
Thank you again.
