By Mayo Clinic staffThe doctor who interprets the HIDA scan images (radiologist) may tell you the results of your scan right away. In other cases the radiologist will send the results to your doctor, who will discuss them with you.
HIDA scan images, as seen on a monitor, appear as regions of dark color and lighter or white areas. The more dark color there is on the image, the greater amount of radioactive tracer was absorbed in that area. Dark color throughout the series of HIDA scan images indicates that the radioactive tracer was able to move freely through your liver, bile ducts, gallbladder and small intestine. If the radioactive tracer wasn't seen in certain HIDA scan images, there may be a blockage or other problem.
Results of a HIDA scan might include:
- Normal. A normal result means that the radioactive tracer moved freely along with the bile from your liver to your small intestine. No problems were detected.
- Slow movement of radioactive tracer. If the radioactive tracer moves through your bile ducts very slowly, this may indicate a blockage or obstruction. Or it may indicate a problem in your liver.
- No radioactive tracer seen in the gallbladder. If the radioactive tracer isn't seen in your gallbladder, this may indicate inflammation (cholecystitis).
- Radioactive tracer detected in other areas. If the radioactive tracer is found outside of your biliary system, this may indicate a leak.
Your doctor will discuss your specific results with you.
