Abstract: Objective To study the value of dual-phase enhanced multi-slice computed tomography (MSCT)scan in combination with the reconstruction technique for distinguishing gallbladder adenomyomatosis (GBA)from gallbladder cancer.Methods We ret-rospectively reviewed the CT features (including dual-phase and reconstructed images)of 36 patients with GBA (Group A,1 6 pa-tients)or gallbladder cancer (Group B,20 patients)proved by pathology.Fisher exact test was used to compare the CT findings be-tween the two groups.Results The occurrence rates of RAS,gallbladder wall smoothing,clear gallbladder border,uniform en-hancement of serous layer and thickening of the gallbladder wall were statistically significantly different between Group A and B. When using the Rokitansky-Aschoff sinuses as a parameter for the differential diagnosis of the two groups,the diagnostic accuracy reached to 92.85%.Conclusion Dual-phase enhanced MSCT scan in combination with the reconstruction technique is a valuable ima-ging technique for distinguishing GBA from gallbladder cancer.
