The most common tests for diagnosing gallstones are

The diagnosis of gallstones usually relies on a variety of tests, with ultrasound being the most common initial diagnostic tool. These tests help doctors confirm the presence, size, and location of the stones, providing the necessary information for developing a treatment plan. Other common tests include CT scans, MRIs, and endoscopic retrograde cholangiopancreatography. Understanding the details of these tests can help patients better cope with the diagnostic process.

1. Ultrasound examination: Ultrasound examination is widely used because it is non-invasive, convenient and does not involve radiation. This method uses sound waves to generate images of the liver and gallbladder area, which can effectively detect the presence and size of gallstones. Ultrasound examination is usually used as a preliminary screening tool for gallstones, especially for gallbladder stones with clear images.

2. CT scan: In some cases, CT scan can provide more detailed abdominal imaging data. This method is helpful to check whether the bile duct is blocked, and it can also find smaller or more complex stones. However, CT scan involves low-dose radiation and should be used with caution in pregnant women and certain special populations.

3. Magnetic resonance pancreatobiliary imaging (MRCP): MRCP is a special MRI technique that provides accurate images of the pancreaticobiliary system without the need for contrast agents. This method carries a low risk of bleeding and is ideal for situations where a detailed bile duct assessment is required, especially when a surgical evaluation is planned.

4. Endoscopic retrograde cholangiopancreatography (ERCP): ERCP is a technique that combines endoscopy with X-rays and is used for both diagnosis and treatment. This method inserts an endoscope into the small intestine through the mouth, and then injects contrast agent through the catheter to clearly show the bile duct and pancreatic duct structure. For patients with concurrent bile duct stones, ERCP can also be used directly for stone removal and related treatment.

Regular physical examinations and health management can effectively reduce the risk of gallstone formation. Maintaining a healthy diet and moderate exercise are essential for the smooth functioning of the digestive system. For patients with gallstones, early attention to symptoms and timely diagnosis and treatment can effectively avoid serious complications. If you have symptoms of gallstones or suspect a history of stones, please seek medical attention in time to obtain professional diagnosis and advice to protect your health.
