YR 1976 UL http://tech.snmjournals.org/content/4/2/74.abstract AB The technical details of a dacryocystoscintigraphic procedure, using a standard pinhole collimator, are presented. Fourteen patients were studied and there were no incorrect interpretations of the results. Standard pinhole collimator seems to be satisfactory for scintigraphic studies of the lacrimal system.
