Whether gallstones need to do CT should be analyzed according to the patient’s specific situation. Generally, patients with gallstones do not need to undergo CT examination, but CT examination can be performed when it is necessary to exclude the thickening of the gallbladder wall, gallbladder cancer and other conditions. Ultrasound has the advantages of high sensitivity to gallstones, no radiation, affordable, non-invasive, fast, etc. Therefore, patients with gallstones usually prefer abdominal ultrasound.CT is not as sensitive as ultrasound in detecting gallstones, and it is expensive and radioactive, so it is not necessary to have a CT examination for gallstones in general. However, when gallstones lead to gallbladder perforation, thickening of the gallbladder wall, cholecystitis and other complications, or when it is necessary to exclude gallbladder cancer and other diseases, it is necessary to perform abdominal CT examination. Abdominal CT examination can exclude the interference of intra-abdominal gas, and the scope of the examination is larger, which can help to find more subtle lesions and determine the condition. Patients with gallstones should choose the appropriate examination method according to the doctor’s advice and guidance, and go to the hospital in time for regular treatment under the doctor’s guidance.
