title: [Nuclear magnetic resonance tomography of the orbits. Initial experiences using the paramagnetic contrast medium gadolinium-DTPA].
abstract: In 21 patients with orbital mass lesions MRI was performed before and after administration of paramagnetic contrast medium, Gadolinium-DTPA. In comparison to the plain scan the differentiation of the tumorous tissue against the surrounding structures was improved after application of contrast medium despite a partially moderate increase in signal intensity. Especially highly vascular tumors and vessel diseases show a significant contrast enhancement. With increasing experience in larger number of patients a tissue differentiation seems to be possible.
