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.
对13例面部创伤、感染后或无既往病史的前瞻性病例进行了磁共振成像泪囊造影和水溶性计算机断层扫描泪囊造影的比较。所有患者均有流泪、溢泪或泪囊炎症状。本研究证明了计算机断层扫描的优越性，对于泪道系统的复杂问题，应首选计算机断层扫描。只有肿瘤性病变（非常罕见）需要磁共振成像。计算机断层扫描和泪囊造影同时进行可提高诊断准确性并减少辐射剂量。计算机断层扫描通过螺旋采集对患者来说更舒适，且比磁共振成像便宜。
