What tests are done to check for gallstones?

The main methods for examining gallstones include ultrasound, CT scans, and magnetic resonance imaging. Ultrasound is the most commonly used initial screening method because it is non-invasive and relatively inexpensive. CT scans and magnetic resonance imaging can observe the size and location of the stones in more detail, providing a basis for further treatment. Choosing the right examination method can help to make an accurate diagnosis and take appropriate treatment measures in a timely manner.

1. Ultrasound examination

Ultrasound is the preferred method for diagnosing gallstones. It uses sound waves to create images. Its advantages are that it does not involve radiation, is non-invasive, and can clearly show whether there are stones in the gallbladder. This examination method is very suitable for determining the size, shape, and number of gallstones. Ultrasound can also evaluate the condition of the gallbladder wall and whether there are other lesions.

2. CT scan

CT scan is an X-ray imaging technology that can provide higher resolution for gallstone images, especially in difficult cases. In the case of complications of gallstones such as cholangitis or pancreatitis, CT scans can help doctors quickly and accurately evaluate the condition. Although the radiation dose of CT scans is higher than that of ultrasound, its detailed image information is irreplaceable when diagnosing complex cases.

3. Magnetic resonance imaging (MRI)

Magnetic resonance imaging is a procedure that uses a magnetic field and radiofrequency waves to produce detailed images of the body's interior. MRI is particularly useful for more complex gallstone cases, such as difficult-to-diagnose common bile duct stones. Because MRI uses no radiation, it is well suited for patients who require multiple imaging procedures. MRI can provide clear images of the biliary system, helping doctors make more precise assessments when planning surgery or other interventions.

After a gallstone test, your doctor may recommend different treatment options based on the results. For example, small gallstones may not require immediate treatment, but only require regular monitoring. Larger gallstones or patients with severe symptoms may require medical lithotripsy, extracorporeal shock wave lithotripsy, or surgery.

Although scientific and technological means have provided guarantees for the accurate diagnosis and effective treatment of gallstones, it is equally important to maintain a healthy lifestyle. A balanced diet, moderate exercise and regular physical examinations are key measures to prevent gallstones. If gallstones have been diagnosed, close cooperation with the doctor's treatment plan and regular checkups will help reduce complications and improve the quality of life. While seeking professional examinations and treatments, we should not ignore the comprehensive adjustment of all aspects of life, maintain a positive attitude and scientific self-management.
