Magnetic resonance dacryocystography: Its role in the diagnosis and treatment plan of lacrimal drainage system obstructions
Journal Title: Dicle Tıp Dergisi - Year 2014, Vol 41, Issue 1
Abstract
Objective: To evaluate the role of magnetic resonance dacryocystography (MR-DCG) technique in patients with obstruction of lacrimal drainage system. Methods: A total of 40 patients who had presented to the ophthalmology clinic were suspected to have obstruction of lacrimal drainage system, were evaluated with MR-DCG after instillation of 0.5% Gd-DTPA conjunctival contrast medium. Dacryocystorhinostomy (DCR) was performed in patients who were found to have lacrimal drainage system obstruction on either side on MR-DCG. Results: Obstruction of lacrimal drainage system was successfully detected in a total of 49 eyes of 40 patients undergoing examination with MR-DCG. The MR-DCG findings of 29 nasolacrimal systems were compared with the intraoperative findings in 28 out of 40 patients who had undergone the DCR operation. The sensitivity of MRDCG was determined as 100% and specificity as 96.7% for identification of nasolacrimal system obstruction when compared with the intraoperative findings, and MR-DCG was found to detect obstruction with high accuracy. Conclusion: MR-DCG has a high success rate in detection of lacrimal drainage system obstructions and the level and cause of the obstruction. Key words: Dacryocystorhinostomy, lacrimal stenosis, MR-dacryocystography
