Change: Dacrocystogaphy is often performed in conjunction with a radionuclide lacrimal study (Lacrimal dacryoscintigraphy). This is the same patient as shown above. When the findings of the two studies correlate well, there can be additional confidence in the results.Technique NotesThe radiologist may choose to View changes from previous version.
