The TDICOMIODItem class has the following Read-Only properties:

Internally LEADTOOLS maintains a tree structure, referred to as the IOD Structure, of available Information Object Definitions (IODs). These IODs can include default IODs available in DICOM, as well as user defined IODs. You can access any of this information, add to the IOD Structure, or delete items from the IOD Structure using the xxxIOD and xxxIODxx methods.

Note: The CurrentIOD property is read only, except that you can explicitly set it to Nil in Pascal or NULL in C++.
