Methods 40 cases with suspected meniscus tear were performed with MRI, by sequences of T1WI, T2WI-FS and SWI. The sensitivities, specificity, accuracy and effect of T1WI, T2WI-FS and SWI were analyzed as compared to the golden standard of arthroscopy. Results The sensitivities, specificity and accuracy of T1WI were 76.3%, 50% and 75%, respectively; those of T2WI-FS were 71.1%, 100% and 72.5%, respectively; and those of SWI were 94.7%, 50% and 92.5%, respectively. There were significant differences between T1WI and SWI (P0.05) on the diagnosis of meniscus tear, with bad conformity (κ=0.391). There were significant differences between T2WI-FS and SWI (P0.05) on the diagnosis of meniscus tear too, with bad conformity (κ=0.288). Conclusion The sequence of SWI can be used into diagnosis of meniscus tear, with better sensitivity and accuracy than the sequences of T1WI and T2WI-FS.
