Based on the provided reference, there is no mention of a "hydra scan." The reference details a HIDA scan, which is a medical imaging procedure for evaluating the gallbladder. Thus, the original question might contain a misspelling or be confused with something else. It is possible you meant to ask, "What is a HIDA scan?" If that is the case, let's explore what a HIDA scan is:
A HIDA scan is an imaging procedure that utilizes a radioactive tracer and a scanning camera to assess the function of your gallbladder. It's used to identify problems with the gallbladder and bile ducts.
Here's a more detailed breakdown:
HIDA Scan Details
| Aspect | Description |
|---|---|
| Full Name | Hepatobiliary iminodiacetic acid scan |
| Purpose | To evaluate the gallbladder and bile ducts |
| Procedure | A radioactive tracer (radiotracer) is injected into the bloodstream. This tracer is then absorbed by the liver and secreted into the bile ducts. A special camera (gamma camera) is used to track the tracer's movement and capture images. |
| Department | Typically performed in the nuclear medicine department of radiology. |
How the HIDA Scan Works:
- A small amount of radioactive tracer is injected.
- The tracer travels through the bloodstream and is taken up by the liver.
- The liver excretes the tracer into the bile, which then passes into the gallbladder and bile ducts.
- A gamma camera detects the radioactive tracer, producing images that show the flow of bile.
- The images are used to diagnose problems, such as blocked bile ducts or gallbladder dysfunction.
What a HIDA scan can reveal
- Gallbladder Function: Evaluates how well the gallbladder is emptying.
- Bile Duct Obstruction: Helps identify blockages in the bile ducts.
- Biliary Atresia: Helps diagnose biliary atresia in newborns.
- Bile Leaks: Checks for bile leaks after surgery.
This more detailed description should clear up any confusion about what a HIDA scan, not a hydra scan, is. It is important to remember that a HIDA scan and the term "hydra scan" are two entirely different things. The former is a real medical procedure while the latter likely does not exist.
