Functional Magnetic Resonance Imaging in Lacrimal Duct Disorders with Conjunctival Application of a Paramagnetic Contrast Agent
نویسندگان
چکیده
Purpose: In epiphora, dacryocystography (DCG) is established for localization of underlying dacryostenosis. DCG is of limited value concerning the depiction of periductal structures, and does not provide functional information e.g. in dysfunction of the canalicular muscle pump or relative stenoses for reasons of active instillation of the contrast agent. Dacryoszintigraphy provides sufficient functional, but no morphological information about lacrimal drainage. Therefore, high resolution magnetic resonance imaging (MRI) of the lacrimal drainage system with Gadolinium-Dimeglumine (Gd-DTPA) eyedrops was evaluated.

متن کاملDynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
