What are the common methods for diagnosing gallstones?

Common methods for diagnosing gallstones include ultrasound, CT scan and MRCP (magnetic resonance cholangiopancreatography).

Ultrasound is a non-invasive, fast and efficient method that forms images on a screen by reflecting sound waves, which can clearly show stones in the gallbladder and pancreatic duct. In most cases, ultrasound is the preferred method to identify the presence of gallstones. CT scan is also an accurate imaging method that can provide detailed location, size and impact of stones on surrounding tissues. MRCP uses magnetic resonance imaging technology to display detailed images of the biliary system in a non-invasive way, which can not only detect stones, but also evaluate abnormalities in the bile duct.

In addition to these main imaging methods, there are some auxiliary diagnostic tests. For example, blood tests can help identify inflammation and bile duct damage and determine whether the stones will cause complications. Oral cholecystography is a less commonly used method. It takes an oral contrast agent and then takes an X-ray to show the stones in the gallbladder. Endoscopic retrograde cholangiopancreatography (ERCP) is not only a diagnostic method, but also can remove bile duct stones during the procedure.

An early and accurate diagnosis not only helps choose the most appropriate treatment plan, but also prevents potential complications. If you experience symptoms such as right upper abdominal pain, jaundice, or fever, you should see a doctor as soon as possible for relevant examinations. Maintaining a healthy diet and proper exercise can reduce the risk of gallstones. When faced with diagnosis and treatment options, fully communicating with your doctor and understanding the pros and cons of each method is an important step in making the best decision. Please be sure to pay attention to your own health, prevention is better than cure.
