Abstract:
Objective To explore the diagnostic value of indirect magnetic resonance(MR) arthrography in detecting meniscus tears of the knees.Methods Routine plain MR of the knees followed by indirect MR arthrography was performed in 56 knees with suspected meniscal tears clinically.All cases had subsequently arthroscopic examination or operation.The sensitivity and diagnostic accordance of routine plain MR and indirect MR arthrography were compared based on the result of arthroscopic examination or operation. Results The signal intensity in the area of meniscal tears on image of indirect MR arthrography was obviously higher than that of routine plain MR.The diagnostic accordance rate of indirect MR arthrography was 78.67% while the routine plain MR was 52.20%,and the difference was statistically significant(?~2=21.066,P
