Simultaneous dacryocystography and dacryoscintigraphy using SPECT/CT in the diagnosis of nasolacrimal duct obstruction

Clin Nucl Med. 2012 Jun;37(6):609-10. doi: 10.1097/RLU.0b013e31824d2751.

Abstract

Epiphora, an abnormal overflow of tears, is commonly caused by tear drainage system anomalies including nasolacrimal duct obstruction. To assess morphologic abnormalities, dacryocystography by CT is used when CT contrast material is syringed into the lacrimal drainage system. To evaluate the function of the system, dacryoscintigraphy is the most readily available noninvasive method. In the case presented, a 43-year-old man was referred to our clinic with an 8 months' history of indefinite left side epiphora. After performing dacryoscintigraphy, we acquired SPECT/CT images during dacryocystography by CT to establish the surgical indication.
