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...

D-SPECT
D-SPECT represents the next step in the evolution of SPECT technology and is based on a unique acquisition geometry. It has nine arrays of cadmium zinc telluride (CZT) detectors, each of which rotates around its central axis with programmable angular rotation 1. The detectors are very compact al...

Indium-111 oxine labeled white blood cell scan
Indium-111 oxine labeled white blood cell (WBC) scan (or In-111 oxine labeled white blood cell scan) is a nuclear medicine test which attempts to localize infection and/or inflammation by injecting the patient's previously extracted and radioactively-labeled white blood cells.

PET radiotracers
A PET radiotracer (also known as PET tracer) is a positron-emitting radiopharmaceutical used in positron emission tomography (PET). Each tracer consists of a positron-emitting isotope (radioactive tag) bound to an organic ligand (targeting agent). The ligand component of each tracer interacts wi...

Krenning score of neuroendocrine tumor uptake
The Krenning score is a proposed semi-quantitative method of assessing the degree of tracer uptake on octreotide scintigraphy.
Parameters
Initially designed for assessment of 111In-DTPA on planar imaging, the Krenning score is applicable to SPECT or PET-CT using various radiopharmaceuticals.

F-18 fluorodeoxyglucose (FDG) embolism
F-18 fluorodeoxyglucose (FDG) embolism is a condition which results in a uniform intense FDG-avid pulmonary focus without any underlying structural CT correlate with an unremarkable follow-up PET-CT scan 1. It is thought to occur as a result of clumping of FDG with blood when the blood is withdr...
