Hepatobiliary Scan with CCK. Before we go into the process of the scan, CCK or cholecystokinin a substance is injected through an IV to contract your gallbladder and assist in accurate capturing of gallbladder functioning. Hence, HIDA scans are also referred to as cholecystokinin hepatobiliary scans.
What is a hepatobiliary scan?
Overview. A hepatobiliary (HIDA) scan is an imaging procedure used to diagnose problems of the liver, gallbladder and bile ducts.

CCK (Cholecystokinin) is an enzyme that causes the gallbladder to contract and empty (and thus push the radiopharmaceutical down the biliary tree to the bowel) A HIDA examine conveys just a couple of dangers. They include: Hypersensitive response to prescriptions containing radioactive tracers utilized for the sweep What is a HIDA scan?
How is CCK administered during liver and gallbladder imaging?
• When the liver and gallbladder are visualized, approximately one hour into imaging, the technologist will administer CCK through your IV. The CCK enzyme causes the gallbladder to contract.
Is a CCK HIDA scan painful?
Pain - If using a HIDA scan with CCK, patients should be warned that the test will likely bring on very similar pain to what they felt previously, especially in the setting of calculus. The test may be very painful.
How long does a CCK HIDA scan take?
The whole scan may last up to 60 minutes as the tracer passes through your liver and into your gallbladder and small intestine. Several more pictures, each lasting a few minutes, may be taken over the next 2 to 4 hours. Each picture will take only a few minutes, but you will have to lie still for the whole test.
What does CCK test for?
CCK increases pancreatic enzyme output and causes gallbladder contraction. Therefore, the CCK test can help to diagnose biliary tract diseases. Cholecystokinin-cholescintigraphy (CCK-HIDA) is the gold standard test for evaluating patients for obstructive cholecystitis or biliary dyskinesia.
Are you put to sleep for a HIDA scan?

Be sure to have a written copy of the order your Physician wrote in case the facility you're calling hasn't yet received the order yet.
What is a HIDA scan?
A HIDA scan is a nuclear medicine procedure in which you will be injected with a radiopharmaceutical (drug that has a radioactive molecule attached to it). This particular radiopharmaceutical is almost completely extracted from the blood by the liver and put into the bile and, therefore, the gallbladder. Thus the gallbladder and biliary tree can be visualized and assessed for obstruction (by, for example, stone or inflammation or mass). CCK (Cholecystokinin) is an enzyme that causes the gallbladder to contract and empty (and thus push the radiopharmaceutical down the biliary tree to the bowel). In some cholecystitis, the gallbladder is weakened and cannot contract effectively and the images after CCK can show this with some calculations.

What is the difference between MRI and CT?
So, from this, you should be able to note one big difference between MRI and CT. CT only gives you one parameter: density. MRI tells you a lot more . It's looking at hydrogen in different contexts and different tissue environments, and we have multiple ways to probe tissue properties, hydrogen density being only one of at least a half dozen properties you can look at, and some of these properties give you interesting multidimensional information.
How does CT work?
CT does use x-rays and the way x-rays interact with tissue is simple as far as imaging is concerned. x-rays pass through tissue and get attenuated as x-ray photons are scattered or absorbed by tissue atoms. The denser the tissue along the x-ray path, the more photons are scattered. So, we send the x-ray through the sample and measure what comes out on the other side. The attenuation measured at the receiver is the total attenuation along the entire line of the x-ray beam.
Can a CT scan cause cancer?
At the base line, what would I say is, there is no evident proof that CT causes cancer. And the studies that have linked-radiation to cancer have many flaws. These should not be used to give cancer risks to people undergoing CT scans. That being said, no one should undergo CT scans (or any scans) without doctor's approval or need.
Is a CT scanner more common in India?
In India and in a lot of developing nations, CT scanners are a lot more common than MRI machines ( partly due to MRI being expensive).The last data recorded in India was 3000 CT scanners and 600 MRI machines.
