Since its approval for clinical use in mid 1988, Gd DTPA has found widespread application as a contrast agent in MRI. This paramagnetic metal ion chelate is used primarily for enhancement of head and spine lesions. Indications for contrast agent use in MRI are summarized drawing upon experience in more than 600 patients and a review of the literature. Enhancement improves both lesion detection and categorization. In head examinations, we recommend use of Gd DTPA for studies of the internal auditory canal, metastatic disease, infarction, infection, meningeal disease, and primary neoplastic disease. In spine examinations, contrast enhancement is employed both for detection of neoplastic disease and in the postoperative back for the differentiation of scar from recurrent disk herniation. Gd DOTA and Gd DO3A-R are new agents within this same class of contrast media.
