What does Dacryocystography mean?

Dacryocystography (DCG) is a diagnostic test for imaging the lacrimal apparatus. Contrast is injected into the lacrimal system, outlining the canaliculi and sac, and thereby identifying the site of obstruction. Dilation of the lacrimal sac often indicates a complete obstruction of the nasolacrimal duct.

When is Dacryocystography used?

Dacryocystography is used to diagnose the condition causing problems with your tear duct. This is a minimally invasive procedure that is performed on an out-patient basis. You will receive an injection of contrast medium, which will allow the interventional radiologist to clearly visualise the lacrimal sac under X-ray.

What is CT Dacryocystography?

CT-dacryocystography for nasolacrimal duct obstruction following paranasal sinus surgery.

Which method is used for Dacryocystography?

Current standard dacryocystography technique includes the injection of a water-soluble agent and the use of topical anesthesia. In this article the dacryocystogram of the normal lacrimal system and those with various types of obstruction are presented.

Which is the correct definition of the term dacryocystography?

plural dacryocystographies. : radiographic visualization of the lacrimal sacs and associated structures after injection of a contrast medium.

Is the dacryocystography performed under local anesthesia?

CT dacryocystography, performed under sterile technique and following local anesthesia, is well tolerated by patients.

How is Mr dacryocystography performed in Milwaukee?

MR imaging was performed with a 1.5T system (Signa Excite; GE Healthcare, Milwaukee, Wisconsin). The gradient system operates with a maximum gradient strength of 33 mT/m and a slew rate of 120 T/m/s. The 3D FSPGR sequence was used to obtain images in the axial and coronal planes.

What is an X ray of the nasolacrimal drainage?

Radiographic examination of the nasolacrimal drainage system after introduction of a contrast agent. X-ray examination of the lacrimal drainage system using a radio-opaque fluid to delineate the interior. An x ray of the tear duct after injection of a dye that is used to help locate a blockage in the duct. Gale Encyclopedia of Medicine.
