Which of the following is not true about gadolinium-based contrast material?

Question

Quizplus · Accepted Answer

Gadolinium-based contrast agents are used in MRI, not CT. Some very ill patients with renal failure who had large doses or multiple doses of gadolinium-based contrast material within a short time frame develop a systemic illness called nephrogenic systemic fibrosis. The degree of contrast enhancement usually varies with the vascularity of tissues. As a general principle, hypervascular tissue displays more intense enhancement than other tissues in both CT and MRI. The neovascularity of many tumors results in their detection with contrast enhanced imaging. One can also differentiate viable tissue from necrotic debris by whether or not a tissue enhances.
