dictionary help| contrast | medical dictionary |
A dye injected intravenously during X-ray studies, for example CT, to enhance the image of a tumour. In MR studies, the contrast is called gadolinium. The use of contrast may rarely result in some adverse effects: it also increases the cost (but also accuracy in many cases) of the scan.
