‡88.6% MR examinations were performed with gadodiamide (Ominscan), 11.4% were performed with Multihance, Magnevist,etc.
‡‡76% received gadoterate
†Seven types of GBCAs were used in MR examinations
* Five types of GBCAs
¶ Gadodiamide, gadopentetate dimeglumine, gadobutrol, etc.
**Seven types of GBCAs
$ Positive association was found between GBCAs and NSF
♯ Insufficiency evidence showed GBCAs was associated with the development of NSF.
