Abstract

We developed MR-dacryocystography as a non-invasive, safer imaging technique for canaliculi, the nasolacrimal duct and lacrimal sac by dropping saline solution and diluted GdDTPA solution into the eye. The diluted Gd-DTPA solution was found to create no local irritation in the eyes of rabbits and normal volunteers. Lacrimal sacs and ducts were well visualized in all of 10 normal volunteers by using the saline solution or the diluted GdDTPA solution. Canaliculi were visualized in 4-7 cases on thin-slice axial images. MR-dacryocystography was suggested to be a useful screening examination for lacrimal outflow disorders.
