It is used to increase the T1 signal intensity while imaging the liver lesions such as benign cysts, hemangioma, and liver cancer. It is excreted into bile by active secretion. [6]

Pharmacokinetics

In those with end-stage renal failure, the clearance rate is only 17% with terminal half-life of 12 times longer than those with normal renal function. [6]
