Correlation between MRI knee and arthroscopy in knee joint injuries
Dr. Devaraja SM and Dr. Ashwin Kumar Patil
In absence of joint effusion, meniscal degeneration and tears may actually decrease in SI on T2 WI. On T2* GRE images however, intrasubstance degeneration and tears generate increased SI. Hence GRE sequence is extremely sensitive to the spectrum of meniscal degeneration and tears. The FSE may underestimate the extent or Grades of MR SI thus mask the tears, which is because of a ghosting artifact or an increase in magnetization transfer as described by Rubin and colleagues. To understand the significance of increased SI in meniscal abnormalities, Stoller et al. developed a MR grading system of meniscal abnormalities and correlated with pathological model. Purposive random technique was used to select minimum of Thirty cases with history of knee trauma which are referred for MRI to Department of Radiodiagnosis; Medical College. MRI (Hitachi Aperto 0.4 Tesla) study has been done using Tl, T2, PD, fat suppression and gradient echo sequences in various planes. Images were studied for meniscal, cruciate ligament, collateral ligaments tear, fluid collections in and around the joint and also for any signal changes in the surrounding bones, muscles and tendons. Then these cases were subjected to arthroscopy.
