Abstract:
Objective To study the clinial application value of MR dispersion arthrography in meniscus tear of knee.Methods The conventional MR scans of 24 knee joints in 24 patients who were considered to have meniscus tear were performed and followed by MR dispersion arthrography.All cases were approved by arthroscope or operation.The results of both convention MR scan and MR arthrography were compared with arthroscope and operation.The sensitivity and the specificity of plain MR scan and MR dispersion scan were evaluated respectively.Results The signal intensity in the area of meniscus tear was obiously highen on MR dispersion scan than that of MR plain scan.The sensitivity was improved from 74.2% to 94.3% ,and the specificity improved from 88% to 94.3%.Conclusion MR dispersion scan is superior to convention MR scan in image quality and sensitivity in detecting meniscus tear.
