Patients with gallbladder polyps need to understand the examination methods of gallbladder polyps, so that they can choose the economically appropriate examination methods and also better cooperate with physicians for treatment. Ultrasound examination is the first choice for gallbladder polyps, which is simple, accurate, non-invasive, inexpensive and easily accepted by many patients, and can accurately show the size, location, number and wall of the polyps. The typical ultrasound of gallbladder polyps shows strong or slightly strong echogenic clusters in the wall of the gallbladder in the form of points, small pieces or sheets, followed by no acoustic shadow, spherical, mulberry, papillary and nodular prominence of the wall of the gallbladder, and even the tip of the polyp can be shown. It can clearly show the location, size, number and local changes of gallbladder polyps, which is a simple and reliable diagnostic method. In addition, ultrasound color Doppler ultrasonography can identify benign polyps or gallbladder cancer by observing high-speed arterial blood flow signals within the gallbladder polyp mass. For gallbladder polyps, CT plain scan examination has a low detection rate and is not a routine screening tool. If the gallbladder polyp is large and malignant gallbladder polyp is suspected or highly suspected on ultrasonography. Further enhancement CT examination is required. Enhanced CT can distinguish tumor from non-tumor gallbladder polyps and can reliably screen for tumorigenic lesions that should be removed.
