Description
CT DCG (Dacryocystography) is a specialized imaging technique used to evaluate the lacrimal drainage system, which is responsible for tear drainage. This procedure involves injecting a contrast medium into the tear ducts, followed by a CT scan. It provides detailed images of the tear drainage pathway, including the lacrimal sac and nasolacrimal duct. CT DCG is particularly useful in diagnosing and locating obstructions or abnormalities in the tear drainage system. It helps in planning surgical interventions for conditions like chronic tearing or recurrent eye infections due to blocked tear ducts.
