Hepatobiliary imaging in nuclear medicine
Hepatobiliary imaging in nuclear medicine can be accomplished with multiple different radiotracers to help evaluate the liver, gallbladder and the biliary ducts. The choice of tracer depends on the clinical question.
Common tracers include:
Tc-99m IDA (iminodiacetic acid) analogs: most commonl...

Tc99m IDA (iminodiacetic acid) analogs
Tc99m IDA (iminodiacetic acid) analogs are hepatobiliary agents in nuclear medicine, used in cholescintigraphy.
These include:
Tc99m-DISIDA: diisopropyl IDA, also known as Hepatolite
Tc99m-Mebrofenin: trimethyl bromo IDA, Choletec TM
Tc99m-PIPIDA: paraisopropyl iminodiacetic acid

Cholescintigraphy
Cholescintigraphy is the use of radiotracers to assess the anatomy and function of the biliary system (and the liver indirectly). Currently, this is most commonly performed with Tc-99m-IDA analogs 1, and "hepatic IDA" imaging gave rise to the more common term "HIDA scan."
Indications
Cholescin...

Couinaud classification of hepatic segments (mnemonic)
Pauli et al published a "handy" way to remember the Couinaud classification of hepatic segments 1.
Make a fist with your right hand. The fingers should be wrapped around the flexed thumb and the fist should face you. The segments are represented by the following:
segment 1: (caudate): the thum...

Congenital portosystemic shunt
Congenital portosystemic shunts are rare, extrahepatic or intrahepatic, anatomical abnormalities shunting blood from the portal venous system to the systemic venous system and, thus, avoiding passage through the hepatic acinus.
Terminology
The term “portosystemic shunt” can be used to refer t...

Congenital intrahepatic portosystemic shunt classification
This congenital intrahepatic portosystemic shunt classification was proposed by Park et al. in 1990 1:
type 1: single large vessel of constant diameter connecting the right portal vein to the inferior vena cava
type 2: localized, peripheral shunt with one or more communications in a single hep...

Serum ascites albumin gradient
The serum–ascites albumin gradient (SAAG) is the difference between the concurrently obtained serum albumin concentration and the albumin concentration of the ascitic fluid obtained during paracentesis.
Pathology
A difference ≥1.1 grams/deciliter (g/dL) indicates portal hypertension as the li...
