Objective To investigate the application value and imaging findings of CT and MRI in diagnosing ACL. Methods A total of 63 cases with knee ligaments injuries in our hospital were selected as study objects,and the CT and MRI data were analyzed retrospectively. Compared the evaluation results and imaging findings. Results Arthroscope was regarded as golden standard, accurate rate of MRI in diagnosing ACL was 95.23%, obviously higher than that of CT (82.54%), the difference was statistically significant (P<0.05). The CT manifestation of ACL injury was the contracture and broadening of the ligament, with the low density of the breaking point. The MRI manifestation of ACL acute injury was T1WI low signal andT2WI high signal of the ligament. Chronic phase was T1WI low signal andT2WI high signal, ligament thickening, twisted and with blurry broken edge. Conclusion Accurate rate of MRI in diagnosing ACL injury was higher than that of CT, it can provide more plentiful information.
