The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. [1] [2] Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system.

A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay , it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from ...
Tc99m-HIDA (Hepatic iminodiacetic acid) Functional biliary system imaging IV In-vivo: Imaging Tc99m-Denatured (heat damaged) red blood cells Red cell volume. Spleen imaging IV In-vitro: Non-imaging Tc99m-Whole red blood cells GI bleeding. Cardiac blood pool imaging Peripheral vascular imaging IV In-vivo: Imaging Tc99m-MAG3 ...
Nuclear medicine myocardial perfusion scan with thallium-201 for the rest images (bottom rows) and Tc-Sestamibi for the stress images (top rows). The nuclear medicine myocardial perfusion scan plays a pivotal role in the non-invasive evaluation of coronary artery disease. The study not only identifies patients with coronary artery disease; it ...
For a bone scan, the patient is injected with a small amount of radioactive material, such as 700–1,100 MBq (19–30 mCi) of 99m Tc-medronic acid and then scanned with a gamma camera. Medronic acid is a phosphate derivative which can exchange places with bone phosphate in regions of active bone growth, so anchoring the radioisotope to that ...
Type II included patients with biliary-type abdominal pain associated with at least one of the following: altered liver enzymes on blood testing, dilated biliary ducts on imaging tests, and delayed bile clearance on HIDA scan. Biliary-type pain in the absence of any sign of biliary or pancreatic alteration was the so-called Type III biliary SOD.
