Objective To compare the efficiency of 3D-T2WI scanning sequence with thin layer and SS-TSE scanning sequence with thick layer for the gallbladder triangle shows before Laparoscopic cholecystectomy. Methods The patients with laparoscopic cholecystectomy were collected from June 2012 to June 2014 in our hospital. Before surgery all the patients were examined by MR cholangiopancreatography (3D-T2WI scanning sequence with thin layer and SS-TSE scanning sequence with thick layer). A total of 166 patients of information was collected. The actual time for scanning and images of the gallbladder triangle was statistically compared. Results The average times of 166 cases of patients with 3D-T2WI scanning were 8 minutes 22 seconds, the standard deviation were 2 minutes 8 seconds; SS-TSE thick layer scanning for five layers were 20 seconds. Both by T test, P＜0.01. The display rate of gallbladder triangle with 3DT2WI thin layer scanning and SS-TSE thick layer scanning was 88.6% (147/166), 84.3% (140/166)respectively; Both by chi-square test, chi-square=1.26, P＞0.01. The findings of Laparoscopic surgery was taken as the gold standard, coincidence rate of 3D-T2WI thin layer scanning and SS-TSE thick layer scanning in the diagnosis of gallbladder triangle was 82.2% (134/163), 77.9% (127/163)respectively, both by the chi-square test, chi-square=0.94, P＞0.01. Conclusion To show gallbladder triangle, the efficiency of SS-TSE thick layer scanning sequence is better than that of 3D-T2WI thin layer scanning
