Objective To analyze the diagnostic values of ultrasonography and computed tomography ( CT) for gallbladder adenomyomatosis.Methods The ultrasound and CT findings of 28 cases of pathologically confirmed gallbladder adenomyomatosis in our hospital were retrospectively analyzed. The diagnostic values of the two imaging tools for gallbladder adenomyomatosis were analyzed with the pathological diagnosis as the gold standard. Comparison of rates was made by chi- square test; multiple comparisons of rates were made by partition of chi- square. Results Before operation, among the 28 patients, 15 were diagnosed with gallbladder adenomyomatosis by ultrasonography, and 9 were diagnosed by CT; the diagnostic rate of CT was 32. 14%, and the diagnostic rate of ultrasonography was 53. 57%. The chi- square test showed no difference between the diagnostic rates of ultrasonography and CT for gallbladder adenomyomatosis ( χ2=2. 63, P = 0. 10 >0. 05) . In addition, the statistical results showed no differences between the diagnostic rates of ultrasonography and CT for various types of gallbladder adenomyomatosis ( segmental type: χ2=0, P=0. 11 >0. 0125; diffuse type: χ2=2. 57, P =1. 00 > 0. 0125; focal type: χ2= 1. 42, P = 0. 23 > 0. 0125) . Conclusion CT and ultrasonography are two important imaging methods for the diagnosis of gallbladder adenomyomatosis. The detection rate of gallbladder adenomyomatosis can be increased through the combination of convex array probe and linear array probe in ultrasonography.
