Tc99m IDA (iminodiacetic acid) analogs are hepatobiliary agents in nuclear medicine, used in cholescintigraphy.
- Tc99m-DISIDA: diisopropyl IDA, also known as Hepatolite
- Tc99m-Mebrofenin: trimethyl bromo IDA, Choletec TM
- Tc99m-PIPIDA: paraisopropyl iminodiacetic acid
The use of IDA alone (Tc99m-IDA) is an older technique and "H"epatic "IDA" scan resulted in the term "HIDA" scan. Tc99m-IDA is seldom used anymore, but the term "HIDA scan" remains.
