Medical uses

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.{{cite web |title=Clinical pharmacology and biopharmaceutics review |url=https://www.accessdata.fda.gov/drugsatfda_docs/nda/2008/022090s000_ClinPharmR.pdf |publisher=Center for drug evaluation and research |access-date=15 December 2022 |archive-url=https://web.archive.org/web/20210512143335/https://www.accessdata.fda.gov/drugsatfda_docs/nda/2008/022090s000_ClinPharmR.pdf |archive-date=12 May 2021}}

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.
