The diagnostic reliability of DSG is limited by the lack of standardization, poor anatomical resolution, poor quality of images, intra- and interobserver variability, low specificity, insufficient correlation with clinical findings, the inability to distinguish stenosis from obstructions, and the inability to assess the results of lacrimal surgery. These limitations raise concerns regarding any justification for its use in everyday lacrimal practice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>DSG is not routinely used by the vast majority of lacrimal surgeons worldwide given that in most cases, it does not profoundly impact clinical decision-making.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/iop.0000000000003003","type":"journal-article","created":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T15:00:08Z","timestamp":1752505208000},"page":"245-252","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["A Comprehensive Review of Dacryoscintigraphy: Part I\u2014Indications, Techniques, and Utility"],"prefix":"10.1097","volume":"42","author":[{"given":"Hatem A.","family":"Tawfik","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Ain Shams University, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhupendra C.
