Comparative Study Of0.2T And Magnetic Resonance Imaging (MRI) In The Diagnosis Of Knee Joint Synovial Plica Syndrome

Purpose: To address the evaluation of low field density MagneticResonance Imaging (MRI) with0.2Tesla (T) or1.5T in diagnosing synovialplica syndrome of knee, and provide the basic theory in studying therelationship between synovial plica and other knee disorder by low fielddensity MRI with0.2T.Methods: All the patients, who were scanned by MRI with0.2T or1.5Tfrom Jan.2011to Dec.2012, were collected in the First Hospital of JilinUniversity, retrospetctively. The knees diagnosed of synovial plica wereincluded for the further research. The age, gender of patients and thepathological sites of knee were analyzed for statistics. The detection rate andsensitivity of low field desity MRI were convinced ultimately.Results: From Jan.2011to Dec.2011,5569patients accepted MRIexamination, including4874cases for0.2T and695cases for1.5T in the FirstHospital of Jilin University. By low field density MRI,611knees werediagnosed for synovial plica syndrome, while96cases were diagnosed by highfield density MRI. Compared with the detection rate of13.8%in high field density MRI, no significant difference was shown in the rate,12.5%, by thelow field density MRI (p>0.05).Conclusion: There is no significant difference of the detection rate betweenlow or high field density with0.2T or1.5T in diagnosing synovial plicasyndrome of knees. Compared to the high field intensity MRI, a low cost willbe paid by the patients in MRI with0.2T. The present study provided atheoretical basis of MRI with0.2T in research of synovial plica syndrome andother knee dysfuction.
