Physiologic MR Imaging of Salivary Gland Tumors

You are being asked to complete one research MRI scan with and without contrast since your most recent clinical evaluation and/or prior imaging has shown the presence of a suspicious salivary gland tumor, prior to your scheduled upcoming surgery. MRI contrast agents act like a dye to make MRI pictures brighter and easier to read. During each MRI scan, you will have an intravenous line (IV line) placed. The IV line allows the contrast agent to be injected into your vein. If you have a history of renal disease you may be asked to complete a blood draw of approximately 2.5cc (½ teaspoon), for glomerular filtration rate (GFR) assessment for participation into the study.
