Answer

Answer

In general, the available gadolinium-based intravascular contrast agents have virtually identical pharmacokinetics and contrast-enhancement characteristics. They are equally suitable for breast MRI. All of these agents shorten T1 and increase tissue relaxation rates, increasing the signal intensity on T1W or spoiled GRE images. Suitable agents include gadolinium dimeglumine, gadoteric acid, gadoteridol, gadodiamide, and gadobenate dimeglumine.
