  • Title: [Dacryocystography using CT and MRI. Comparative study apropos of 13 clinical cases].
    Author: Helies P, Cosnard G, Pharaboz C, Maille M, Maurin JF.
    Journal: J Fr Ophtalmol; 1995; 18(12):763-70. PubMed ID: 8745709.
    Abstract:
    Magnetic Resonance Imaging of a dacryocystography and a watersoluble computed tomographic dacryocystography were compared in 13 prospective cases after facial traumas, infections or without previous history. All had either watering eyes, ephiphora or dacryocystitis. This study demonstrated the superiority of computed tomography which must be used in first intention for complexe problems of the lacrimal drainage system. Only tumoral pathology (very rare) requires Magnetic Resonance Imaging. Combined computed tomography and dacryocystography in the same time provide diagnostic precision and less radiation. Confortable for the patient by helicoidal acquisition, computed tomography is cheaper than a Magnetic Resonance Imaging.
